A mountain the size of a major Rocky Mountain peak is sitting under the Pacific Ocean north of Palau, and we finally have a map of it. The top rests about 800 feet below the surface, yet the whole <a href="https://www.earth.com/news/hidden-plastic-graveyard-uncovered-in-the-deep-mediterranean-sea/">structure</a> climbs roughly 2.6 miles from the deep seafloor.



The discovery comes from a NOAA Ocean Exploration cruise that focused on a rarely mapped stretch of ocean. The team put time on task, swept the area with high resolution acoustics, and confirmed the feature’s size and shape.



<h2 class="wp-block-heading" id="h-hidden-ocean-mountain-discovered">Hidden ocean mountain discovered</h2>



The first public look at this feature appeared in a field <a href="https://oceanexplorer.noaa.gov/expedition-feature/live-from-the-field-updates-from-garret/" target="_blank" rel="noreferrer noopener">log</a> posted on September 2, 2025, which described the mountain about 250 miles north of Palau and noted its summit depth and scale. That early report also set the stage for future dives and sampling.



This account comes from <a href="https://oceanexplorer.noaa.gov/multimedia/garret-odonnell-with-noaa-ship-okeanos-explorer/" target="_blank" rel="noreferrer noopener">Garret O’Donnell</a> of NOAA Ocean Exploration, a 2025 <a href="https://seagrant.noaa.gov/communities/students/graduate-fellows/knauss-fellowship-program/" target="_blank" rel="noreferrer noopener">John A. Knauss</a> fellow aboard NOAA Ship <a href="https://oceanexplorer.noaa.gov/okeanos/" target="_blank" rel="noreferrer noopener">Okeanos</a> Explorer. He is part of the mapping team that turned raw sonar pings into a usable chart of the seamount.



“It’s funny to me that were we not actively mapping these features, we would have no idea that a mountain half the height of Mount Everest lies directly beneath us," O'Donnell enthused. 



"Maybe one day the map we made of this behemoth will be used to navigate the feature with a remotely operated vehicle to get a closer look."



The numbers are straightforward and worth stating clearly. The peak sits about 800 feet down, and the full height from the abyssal plain to the summit is about 2.6 miles.

<h2 class="wp-block-heading" id="h-why-seamounts-matter">Why seamounts matter</h2>



A seamount is an <a href="https://oceanexplorer.noaa.gov/ocean-fact/seamounts/" target="_blank" rel="noreferrer noopener">underwater mountain</a>, most often the remains of an extinct volcano that never broke the surface or later sank below the waves. 



Less than one tenth of a percent of the world’s seamounts have been explored, a figure that captures how much frontier still exists in the deep <a href="https://www.earth.com/news/world-turtle-day-2025-ancient-creatures-with-modern-challenges/">ocean</a>.



Scientists estimate there are more than 100,000 large seamounts on Earth when you count those taller than about 3,280 feet. That global count was formalized in a 2010 <a href="https://topex.ucsd.edu/sandwell/publications/127.pdf" target="_blank" rel="noreferrer noopener">study</a> that combined satellite and ship data to build a census.



Why do these mountains matter for life in the ocean? Their shape changes currents, concentrates food, and creates habitats that attract fish, corals, and marine mammals.



This point was underscored by NOAA’s national marine sanctuaries team in a 2025 <a href="https://sanctuaries.noaa.gov/news/2025/reasons-seamounts-matter.html" target="_blank" rel="noreferrer noopener">explainer</a> on why seamounts matter.



The new map north of Palau gives researchers a fixed target for future biological work. It also gives navigators and managers a better picture of the seafloor in a region where charts can still be sparse.



<h2 class="wp-block-heading" id="h-mapping-the-new-ocean-mountain">Mapping the new ocean mountain</h2>



The workhorse tool was <a href="https://oceanexplorer.noaa.gov/technology/sonar-multibeam/" target="_blank" rel="noreferrer noopener">multibeam sonar</a>, an array that sends out many sound beams and times their echoes to build a detailed picture of the seafloor. 



Each pass traces a swath under the ship, and careful overlapping tracks stitch those swaths into a complete map.



Teams call the survey <a href="https://www.earth.com/news/unprecedented-collapse-panamas-ocean-upwelling-fails-for-the-first-time-in-40-years/">pattern</a> “mowing the lawn,” because it is an even, methodical sweep that favors coverage and consistency. 



That approach is slow, but it is the way to find steep slopes, ledges, and summit shapes that single passes can miss.



Precision matters, so crews run regular checks to keep the data within tight error limits. When the seas cooperate, this produces clean coverage that captures the real outline of a feature rather than a guess based on sparse lines.



<h2 class="wp-block-heading" id="h-palau-sanctuary-setting">Palau sanctuary setting</h2>



The mountain rises inside waters tied to the <a href="https://marine-conservation.org/blue-sparks/projects/palau-nms/" target="_blank" rel="noreferrer noopener">Palau National Marine Sanctuary</a>, a <a href="https://picrc.org/work/palau-national-marine-sanctuary/" target="_blank" rel="noreferrer noopener">policy</a> that closed about 80 percent of the nation’s exclusive economic zone to extractive activity on January 1, 2020. 



This makes the area a natural lab for documenting geology and life with less pressure from fishing.



Palau’s sanctuary sits near deep water that drops quickly from the island shelf. That geography lets research ships reach study sites in hours rather than days, which helps when a weather window appears.



Protected status also changes the kinds of questions teams can ask. With a baseline in place, future work can track how untouched seamount habitats function over time.



<h2 class="wp-block-heading" id="h-explaining-the-size">Explaining the size</h2>



The summit at roughly 800 feet makes this feature accessible to surface ship sensors and, with the right systems, to human tended or autonomous vehicles. 



The full height of about 2.6 miles shows it is not a small bump, but a major structure that would not look out of place among prominent continental <a href="https://www.earth.com/news/national-dolphin-day-2025-honoring-the-oceans-most-playful-minds/">peaks</a>.



For context, that height is in the same league as well known mountains on land. The comparison helps illustrate how much topography is hiding in plain sight beneath open water.

<h2 class="wp-block-heading" id="h-ocean-mountain-maps-matter">Ocean mountain maps matter</h2>



A remotely operated vehicle (ROV) can now be guided to interesting ledges and slopes rather than wandering. 



Targeted transects can record sponge and coral communities, fish schools, and any signs of mineral crusts that often coat old volcanic rock.



Water sampling can pair with environmental DNA (<a href="http://edna/" target="_blank" rel="noreferrer noopener">eDNA</a>) analysis to list species without seeing them directly. Those data can set a baseline for the site, which is essential for tracking change.



Good <a href="https://oceanservice.noaa.gov/facts/bathymetry.html" target="_blank" rel="noreferrer noopener">bathymetry</a> improves navigation by reducing the chance of surprise shallows or pinnacles near shipping routes. 



It also makes tsunami and circulation models more accurate, since seafloor shape affects how waves and currents move energy.



For research planning, a complete map is the difference between blind searching and directed work. It saves days of ship time and compresses campaigns into focused operations.



<h2 class="wp-block-heading" id="h-future-seamount-mapping">Future seamount mapping</h2>



The expedition that produced this map connects to a larger push to chart and understand Palau’s deeper waters. 



<a href="https://www.noaa.gov" target="_blank" rel="noreferrer noopener">NOAA</a> has outlined a multi-cruise <a href="https://www.aoml.noaa.gov/3-research-cruises-depart-to-improve-understanding-of-atlantic-and-southern-ocean/" target="_blank" rel="noreferrer noopener">plan</a> in the region, working with local partners to collect high resolution mapping data across the sanctuary.



Each new map reduces uncertainty and opens the door to more detailed work. It is a steady build toward a fuller view of the Pacific floor near Palau.



The global picture still frames the task. A widely cited census estimated more than 100,000 large seamounts worldwide, which shows how much there is left to find and study.

Massive underwater mountain discovered that is larger than some peaks in the Rockies

A mountain the size of a major Rocky Mountain peak is sitting under the Pacific Ocean north of Palau, and we finally have a map of it. The top rests about 800 feet below the surface, yet the whole structure climbs roughly 2.6 miles from the deep seafloor.

In an interview with Piers Morgan for British television station <a href="https://www.itv.com/">ITV</a>, President Donald Trump once again reminds the world that he does not take climate change seriously. 

When asked about the existence of <a href="https://www.earth.com/news/humans-driving-climate-change/">climate change</a>, the President said: “There is a cooling, and there’s a heating. I mean, look, it used to not be climate change, it used to be global warming. That wasn’t working too well because it was getting too cold all over the place.”

President Trump, who often accuses the media of sharing fake news, does not seem to have his own facts straight on the subject of climate change, which is a regional or global change in climate patterns that is largely attributed to carbon dioxide emissions. 

While the President suggests that climate change and global warming are interchangeable terms, they are not. According to the <a href="http://www.noaa.gov/">National Oceanic and Atmospheric Administration</a> (NOAA), “global warming is one symptom of the much larger problem of human-caused climate change.”

Another reality that the President seems to be confused about is that Arctic sea ice reached record lows in 2016 and 2017. Trump said in the interview: “The ice caps were going to melt, they were going to be gone by now, but now they’re setting records. They’re at a record level.”

Last month, the Trump administration removed climate change from the country's National Security Strategy (NSS), claiming that it does not pose a threat to the United States. Prior to this, President Trump’s withdrawal from the Paris Accord shocked leaders and activists across the globe.

President Trump told Piers Morgan that the Paris Agreement would have been a disaster for the United States. However, the President did admit that there could be a way back for the United States.

“I believe in clean air. I believe in crystal-clear, beautiful… I believe in just having good cleanliness in all. Now, with that being said, if somebody said go back into the Paris accord, it would have to be a completely different deal because we had a horrible deal,” said Trump.

President Trump: The Piers Morgan Interview was produced by ITV Studios Daytime and also by Morgan's company, Ferret Productions.

Trump confuses climate change facts in new interview

In an interview with Piers Morgan for British television station...

A team of researchers led by <a href="https://www.stanford.edu/">Stanford University</a> has taken a closer look into what actually happens after influential companies make zero-deforestation pledges. The study revealed that such promises often fall short of having a positive impact, and the experts have some recommendations for policy solutions.

“The time is ripe to increase the scope and impact of zero-deforestation commitments by transnational companies,” said study lead author Eric Lambin. “They align with a growing availability of monitoring data from satellites and other sources as well as a proliferation of national and international public policies aimed at conserving forests to reduce greenhouse gas emissions.”


Hundreds of corporations have made public pledges to help end <a href="https://www.earth.com/news/deforestation-amazon-fish-yields/">deforestation</a> in response to increased expectations from customers and pressure from environmental groups. The researchers are explaining why some of these promises are more dependable than others.

They say that many companies use vague language in stating their goals or have widely varying targets across many different sectors. Some companies have aligned to make collective public pledges, but they rarely specify who will be accountable for the transformation. 

The study co-authors refer to previous studies which revealed that less than 50 percent of sustainability pledges have been implemented among companies in the Sustainability Consortium, a non-profit organization with members including General Mills, Mars, and Walmart.

The experts say that a private zero-deforestation initiative can be undermined by many external factors, regardless of the approach. For example, when an intervention restricts the production of commodities in one place, it can simply encourage displacement of production to other locations.

The researchers highlight several policy approaches to making sustainability projects more effective, verifiable, and customized for each particular region. They suggest that policy makers endorse and reinforce company standards in order to complement the new regulations.

“These companies stand poised to break the link between commodity production and deforestation,” said coauthor Holly Gibbs. “To do that, more immediate action is needed to demonstrate commitment to change and to clear the haze surrounding these efforts.”

The study is published in <a href="http://www.nature.com/nclimate">Nature Climate Change</a>.

Large companies are falling short of zero-deforestation promises

A team of researchers led by Stanford University has taken...

Researchers from the <a href="https://www.ubc.ca/">University of British Columbia</a> are reporting that warm-blooded animals have a better chance of adapting to <a href="https://www.earth.com/news/climate-change-california-vegetation/">climate change</a> than cold-blooded animals. The research was based on over 270 million years of data on animals such as birds, mammals, reptiles, and amphibians.

“We see that mammals and birds are better able to stretch out and extend their habitats, meaning they adapt and shift much easier,” said lead author Jonathan Rolland. “This could have a deep impact on extinction rates and what our world looks like in the future.”


The researchers compared data from the current distribution of animals with fossil records and phylogenetic information for 11,465 species. The team reconstructed where animals have lived over the past 270 million years and analyzed what temperatures they needed to survive in these regions.

The study revealed that the Earth's changing climate throughout history significantly impacted where animals resided. For example, warm and tropical conditions 40 million years ago made the planet suitable for many species to thrive. 

Birds and mammals were able to adapt during the subsequent cooling phase of the planet, which enabled them to move into extreme northern and southern regions.

“It might explain why we see so few reptiles and amphibians in the Antarctic or even temperate habitats,” said Rolland. “It's possible that they will eventually adapt and could move into these regions but it takes longer for them to change.”

According to Rolland, animals that can regulate their body temperatures might be better able to survive in these places because they can keep their embryos warm and take care of their offspring.

“These strategies help them adapt to cold weather but we rarely see them in the ectotherms or cold-blooded animals,” said Rolland.

The research team believes that understanding the past evolution and adaptations of species can provide important insight into how future climate change may impact Earth’s biodiversity.

The study is published in <a href="https://www.nature.com/natecolevol/">Nature Ecology</a>.

Birds and mammals are the most likely to survive climate change

Researchers from the University of British Columbia are reporting that...

Greenhouse gas emissions and warmer temperatures have brought the Earth to a point of no return as far the impacts of global warming are concerned. 

But even though the effects of climate change are being felt with increasing severity, reducing emissions is vital to the preservation and conservation of resources as well the biodiversity of ecosystems. 

Now, new research has found that unless emissions are reduced to meet the same goals at the Paris Accord, almost half of all California’s natural vegetation will be at risk from climate stress, and that’s excluding factors like increased wildfires or insect attacks. 

The study was conducted by researchers from the<a href="https://www.ucdavis.edu/"> University of California, Davis</a> and published in the journal Ecosphere. 

The results show that if <a href="https://www.earth.com/news/california-water-conservation-benefits/">California</a> were to cut carbon emissions to meet the projected goals set by the Paris Accord, the amount of vegetation at risk would be cut in half. The Paris Accord aimed to halt global temperatures from increasing past two degrees. 

“At current rates of emissions, about 45-56 percent of all the natural vegetation in the state is at risk, or from 61,190 to 75,866 square miles," said James Thorne, the lead author of the study. “If we reduce the rate to Paris accord targets, those numbers are lowered to between 21 and 28 percent of the lands at climatic risk.” 

The researchers created maps of California under different climate scenarios, and each map highlights the risk to the state’s wide range of vegetation. 

The business-as-usual map shows that over half of all vegetation in southwestern California, the Central Valley, and the Sierra Nevada is at risk. 

The maps were commissioned by the <a href="https://www.dfg.ca.gov/">California Department of Fish and Wildlife </a>and is helping aid policymakers, state agencies, and land managers in creating a plan for mitigating the effects of climate change and persevering California’s natural resources. 

“In California, we have good information on the vulnerability of fish and wildlife to climate change,” said Whitney Albright, a project manager with the California Department of Fish and Wildlife. “But we were missing this crucial piece of climate risks to underlying habitat. This study helped fill the information gap. We've already started to use its data in our conservation planning efforts.”

Climate change puts half of California vegetation at risk

Greenhouse gas emissions and warmer temperatures have brought the Earth...

Experts at the <a href="https://www.utexas.edu/">University of Texas at Austin</a> have discovered that changes in the circulation of the Atlantic Ocean have influenced rainfall in the Western Hemisphere for thousands of years. This is a significant breakthrough that will help scientists understand how the interaction of these systems affected Earth’s climate in the past, leading to better predictions for the future.

“The mechanisms that seem to be driving this correlation [in the past] are the same that are at play in modern data as well,” said lead author Kaustubh Thirumalai. “The Atlantic Ocean surface circulation, and however that changes, has implications for how the rainfall changes on continents.”

The changing currents in the <a href="https://www.earth.com/news/sea-snakes-atlantic-ocean/">Atlantic Ocean</a> are a key component of Earth’s climate, shifting warm water from the tropics toward the poles. 

The research team took a detailed approach to tracking ocean circulation changes by studying three sediment cores extracted from the seafloor of the Gulf of Mexico. The cores provided the researchers with insight into factors which affected the strength of the Atlantic Ocean current over the past 4,400 years in 30-year increments.


“If we go back in increments of 30, we're well positioned to understand things on the order of centuries,” said Thirumalai. “And the question we decided to ask was what can those reconstructions of temperature and salinity tell us about the greater Atlantic Ocean surface circulation.”

The study revealed that the Atlantic Ocean surface circulation was much weaker during the Little Ice Age compared to how it is today. 

Next, the researchers set out to determine if ocean currents in the Atlantic corresponded with rainfall in the Western Hemisphere, and how this association may have changed over time. The experts found that Atlantic Ocean surface currents correlated with rainfall patterns both in the past and the present.

“It was remarkable,” said Thirumalai. “These patterns that are based on decadal analysis of modern data, and then the hydroclimate proxies that give the salinity in the oceans and the rainfall on land seem to show the same picture.”

The findings of this research highlight a strong association between activity in the Atlantic Ocean and rainfall patterns, as well as the far-reaching impacts of this interaction.

“The study demonstrates a robust century-scale link between ocean circulation changes in the Atlantic basin and rainfall in the adjacent continents during the past 4,000 years,” said study co-author Terry Quinn. “And hence it provides a baseline for predictions on how that part of the climate system may behave in the future.”

The research is published in the journal <a href="https://www.nature.com/ncomms/">Nature Communications</a>.

Atlantic Ocean currents influence rainfall patterns

Experts at the University of Texas at Austin have discovered...

On Thursday, the <a href="https://www.epa.gov/">Environmental Protection Agency</a> announced it would roll back a 1995 regulation on major polluters known as the “once in, always in” policy.

The change would allow companies identified as “major sources” of hazardous air pollution to be reclassified as “area sources” once they’ve limited their air pollution emissions below a certain threshold. 

Under the 1995 policy, once a company fell on the list of major polluters it would always be subject to “major source” air pollution standards, whether or not it addressed its pollution problems.

“This guidance is based on a plain language reading of the statute that is in line with EPA’s guidance for other provisions of the Clean Air Act,” said Bill Wehrum, assistant administrator of the EPA’s Office of Air and Radiation, in a news release. “It will reduce regulatory burden for industries and the states, while continuing to ensure stringent and effective controls on hazardous air pollutants.”

The change will reduce “unnecessary regulatory burdens” on businesses that may deter businesses from attempting to reduce pollution, the EPA news release said. A number of states, organizations and industries requested the change, the agency said.

But some conservationists are criticizing the change. 

“This is among the most dangerous actions that the Trump EPA has taken yet against public health,” John Walke, the <a href="https://www.nrdc.org/media/2018/180125-0">Natural Resource Defense Council</a>’s clean air director, said in a statement. “Rolling back longstanding protections to allow the greatest increase in hazardous air pollutants in our nation’s history is unconscionable.”

The change will “drastically weaken” regulations meant to protect people from health problems like cancer, brain damage and infertility linked to mercury, lead, arsenic and other toxins that released into the air by major polluters, Walke said.

The rollback is an “appalling attack” on public health, John Coequyt, the global climate policy director for the environmental group Sierra Club, told <a href="https://www.cnn.com/">CNN</a>.

The <a href="https://www.epa.gov/laws-regulations/summary-clean-air-act">Clean Air Act</a> defines a “major source” of pollution as a company or facility that emits 10 tons per year of any single hazardous air pollutant, or 25 tons per year or more of a combination of hazardous air pollutants. Facilities that have the potential to emit air pollution at those levels can also be defined as major sources.

According to Thursday’s announcement, the EPA determined that it didn’t have the authority to ban facilities from being reclassified as “area sources” once their hazardous emissions fall below the major source threshold.

EPA rolls back 'once in, always in' regulation on major polluters

It’s eclipse time again! This week, a total lunar eclipse will be visible during the early hours of January 31st. 

Lunar eclipses are only possible when the moon is full, and January 2018 will be one of the rare months with two full moons, also known as a blue moon. 

Unlike the <a href="https://www.earth.com/image/great-american-total-solar-eclipse/">solar eclipse</a> of 2017, you can safely watch the lunar eclipse without eye protection, and the lunar eclipse will be visible to anyone who gets up early enough to see it if skies are clear. 

According to <a href="https://www.jpl.nasa.gov/edu/news/2018/1/18/how-to-watch-a-total-lunar-eclipse-and-get-students-observing-the-moon/?utm_source=iContact&amp;utm_medium=email&amp;utm_campaign=NASA/JPL%20Edu&amp;utm_content=edunews_20180124">NASA’s Jet Propulsion Laboratory</a> (JPL) at the <a href="http://www.caltech.edu/">California Institute of Technology</a>, for those in North America, the coming lunar eclipse will be the only total lunar eclipse event visible this year. 

“For the (continental) U.S., the viewing will be best in the West,” said Gordon Johnston, a program executive and lunar blogger. “Set your alarm early and go out and take a look.”

Eclipses are only possible when the stars and planets align in a specific way. For a solar eclipse, it happens when the moon moves between the Earth and sun during its orbit around the Earth. The moon casts a shadow as it blocks the light and moves in front of the sun. 

A lunar eclipse occurs when the sun, moon, and Earth are on the same plane with the sun and moon on opposite sides of the Earth, and the Earth casts a shadow over the moon. 

The coming eclipse is noteworthy for three reasons. It’s a supermoon as the moon will be brighter than usual, it’s a blue moon because it’s the second full moon in the same month, and during the actual eclipse the moon will turn a reddish color making it a blood moon. 

The “Super Blue Blood Moon” will begin on January 31st in the middle of the night, and the total lunar eclipse will start just before dawn 

For those lucky enough to be graced with clear skies, the total lunar eclipse will be a site not to be missed.

It’s well known that <a href="https://www.earth.com/news/climate-change-sea-turtles/">climate change</a> will be having a major impact on coastal regions around the world as glaciers and ice sheets melt, causing sea level to rise globally. But now this isn’t just a concern for the future, as for the first time an international research team has discovered evidence that sea-level rise is already affecting high and low tides in both the Chesapeake and Delaware bays. 

Through combining a computer model with 100 years of observations, the researchers found that global sea-level rise is increasing the tidal range — which is the distance between high and low tides — in many areas throughout each bay. 

In 2015, Andrew Ross, a meteorology doctoral student at <a href="http://www.psu.edu/">Penn State</a>, noticed a bizarre pattern occurring while testing a numerical computer model for tidal research. A distinct pattern of changes to the high and low tides of Chesapeake Bay would result upon adding one meter of sea-level rise. “We weren’t sure why it was there, but it was unique enough that we thought it should show up in observations, too, if it was actually real,” says Ross, now a postdoctoral research associate, Princeton University. “So we started looking at the observations, doing more comparisons.”

Together with a team of researchers, Ross began working to pinpoint the precise effects of sea-level rise through subtracting other forces that affect changes to the tidal range. These forces include predictable ones such as the orbit of the moon around Earth, as well as less predictable ones like the effect of dredging a bay. They also analyzed tidal gauge records from 15 locations in the Delaware and Chesapeake bays, the oldest of which dated back to 1901.

The researchers paired information from isolated data of the influence of sea-level rise on tides to a computer model that could adjust the overall sea level, simulating the effects of either the past or future. They found that both the tide gauge data and the model generally agreed on the main effects of sea-level rise on tides. Analysis showed that one meter of sea-level rise increased the tidal range by up to 20 percent in some areas. Based on the physical characteristics of the bay, sea-level rise varied. “In the Delaware Bay, as you go upstream toward Philadelphia, the shore lines are converging in a sort of funnel shape, and so we see that amplifies sea-level rise’s effects on the tides,” said Ross. “That amplification gets magnified the farther you go upstream.”

For the Chesapeake Bay, the shape resulted in a different pattern of effects – in some cases slightly decreasing the tidal range. The shape of the bay is longer and less of a funnel, compared to the Delaware Bay. When a wave enters the Chesapeake Bay from the ocean, it hits the end of the bay and reflects back towards the ocean, either adding to or subtracting from the size of the waves it hits. Waves travel faster in deeper water, so a higher sea level leads to faster wave speed. This changes where incoming and outgoing waves meet, which can have a cascading effect on tide patterns throughout the bay.

“When people think about flooding associated with sea-level rise, they often think everything will just go up, including the tides, but the reality is that in some cases, the tidal range may stay the same or decrease,” explains Raymond Najjar, a professor of oceanography at <a href="http://www.psu.edu/">Penn State</a>. “It all depends on the geometry of the bay and the speed of waves, which we know are affected by rising sea levels.”

Climate change has already altered the Delaware, Chesapeake bays

It’s well known that climate change will be having a...

Last summer I travelled with my partner Erin throughout the state of Colorado.  Most of our trip was climbing mountains but we also hiked to alpine lakes, camped in the woods, wandered Great Sand Dunes National Monument.  

At first I thought it was an isolated incident, someone hiking a 14er (mountain of 14,000 ft +) with a wireless speaker playing their music.  I cringed, myself preferring the sound of squeaking Pikas and Marmots to music while in the mountains.  

Then it happened again.  As I was descending Mt. Massive above tree line, a man playing loud rock music stopped me to ask how far it was to the summit.  I was polite but inwardly angry.  How is it this man’s right to impose his music on other hikers, much less wildlife, especially in a wilderness area?  Wandering on the sand dunes at night near the trickle of a stream, Erin and I went looking for stars and a place to lay on the sand and watch them.  Tourists played their music as they wandered on the dunes near us, shattering any illusion of solitude, destroying the remnant of quiet nature.

Finishing up with a bouldering session near Tucson this winter, a man with blonde dreadlocks asked us if it was ok to play music while he and his partner climbed on the other side of the boulder.  I felt a little better that at least I was being asked for my permission.  Erin and I were leaving anyway and said that music was ok, we were heading out.

Running through parks or even hiking on trails, headphones are omnipresent and they give an easy excuse for ignoring other people around you.  Headphones are a poor substitute for solitude though, they only create a wall, not a place of self-reflection or connection to the Earth.  I watched a woman moving up a mountain in Colorado, listening to her headphones; as the woman hiked quickly uphill, clouds gathered and thunder rumbled ominously.  Thunder is a dangerous situation at that elevation, especially when moving up the mountain.  I wondered if the woman was fool hardy, inexperienced or perhaps tuned out of her immediate environment by music, not being fully present on a mountain full of hazard.

The last time I went into REI to price and compare different climbing rope, something clicked.  It wasn’t that hundreds of people decided on their own that wireless speakers and music were good to carry into the outdoors.  Wireless speakers were being marketed for outdoor recreation.  I understand some music, especially if you’re out in a remote location for months, it can be comforting.  The main problem is when we never turn off our music and listen to our surroundings or connect to each other.  A mountain is NOT a gym, it is a sacred place, listen to it.  A fellow hiker is NOT a distraction or annoyance but a person with whom you might share more than you suspect.  Wildlife should be respected, watched, loved at a distance and not disturbed by your inconsiderate music. Can you imagine a world where music is always playing?  Would you replace bird song with Bob Marley’s Three Little Birds?  I love both and both have their place but bird song lives deeper within us than human music.

Some would argue that at least people listening to music are getting outside.  Isn’t what we want is more people outdoors?  I would argue that more people aren’t getting outside because of portable music, instead it’s changing the reality for people who already get outside.  

Stats from the National Parks Service suggest that in <a href="https://www.earth.com/news/national-parks-trump-ghost-teddy-roosevelt/">National Parks</a> at least, a smaller percentage of the population is recreating out of doors.  I don’t think access to an iPod is going make a person take to a mountain trail instead of a gym treadmill but even if it does it highlights the problem.  Using portable music creates the illusion that you are in an environment, let’s say a gym, that is under human control.  As more and more people learn to rock climb not on a cliff face but inside of a gym, it’s ever more important to emphasize the difference between the two.  Climbing in a gym can be a real challenge and the hardest climbs are much harder than the easiest outdoor climbs but the outdoors offers so much more.  You aren’t likely to be surprised by an encounter with a wild animal or caught in a rainstorm inside of a gym.  

Cacti, trees, clouds, rattlesnakes and dirt are all minimized inside gyms.  A gym also has one major difference from outside, a gym can be anywhere.  A climbing gym in Rapid City South Dakota looks very similar to a climbing wall in Grand Junction, Colorado but the outside climbing is radically different.  In South Dakota you’d be climbing dark granitic rock surrounded by ponderosa pine.  In Grand Junction it’d be light colored sandstone surrounded by high desert piñon-juniper woodlands.  It’s the natural environment and the unobstructed, wild freedom that goes with it which is threatened, not a trip to the gym and not your music.  

Further down the line, I worry that people absorbed in their own music will miss wildlife.  In missing wildlife, there may be no awareness when the forests, mountains and deserts are bereft of wild creatures.  The scariest thing of all is a loss of a wild environment without anyone even noticing.

A new study has revealed that sandwiches are having a substantial impact on <a href="https://www.earth.com/news/oceans-buffer-greenhouse-gas/">greenhouse gas emissions</a>. In the first study of its kind, researchers at <a href="http://www.manchester.ac.uk/">The University of Manchester</a> have tracked the carbon footprint of a sandwich by examining its entire life cycle including production, packaging, and food waste.

The research team focused on 40 sandwich recipes for their investigation. The highest carbon footprints were found in sandwiches that contained bacon, ham, or sausage, as well those made with cheese or prawns. 

The most carbon intensive process was discovered in sandwiches served on all-day breakfast menus that include eggs, bacon, and sausage. The study revealed that the production of just one of these sandwiches generates a carbon dioxide equivalent (CO2 eq.) that is comparable to driving a car for 12 miles.

The lowest carbon footprint was found in a sandwich made at home with ham and cheese. Furthermore, the study demonstrated that sandwiches made at home could reduce carbon emissions in half compared to eating out.

According to the British Sandwich Association (BSA), more than 11.5 billion sandwiches are consumed each year in the UK. Around half of those are made at home and the other half are bought in shops, supermarkets, and service stations.

“Given that sandwiches are a staple of the British diet as well as their significant market share in the food sector, it is important to understand the contribution from this sector to the emissions of greenhouse gases,” said study co-author Adisa Azapagic.

“For example, consuming 11.5 billion sandwiches annually in the UK generates, on average, 9.5 million tonnes of CO2 eq., equivalent to the annual use of 8.6 million cars.”

The researchers established that the biggest contributor to the carbon footprint of a sandwich is the agricultural production and processing of the ingredients, which generates up to 67 percent of the CO2 eq. for fast food sandwiches. In addition, the refrigeration of sandwiches in the supermarket can account for up to 25 percent of their overall contribution to emissions.

“We need to change the labelling of food to increase the use-by date as these are usually quite conservative,” said Professor Azapagic. “Commercial sandwiches undergo rigorous shelf-life testing and are normally safe for consumption beyond the use-by date stated on the label.”

The study authors pointed out that reducing certain ingredients that have a higher carbon footprint such as cheese and meat would not only help to cut back on greenhouse gas emissions, but would also contribute to healthier diets with less calories.

The research is published in the <a href="https://www.journals.elsevier.com/sustainable-production-and-consumption/">Journal of Sustainable Production and Consumption</a>.

The severe <a href="https://www.earth.com/news/smoke-toxic-gases-wildfires/">wildfires</a> that plagued California during the summer and fall of 2017 cost millions in damages was just another indication of the increasing effect of climate change. 

As temperature increase and droughts become more and more frequent, the risk of fires will also increase. 

<a href="https://www.nasa.gov/">NASA</a> satellite instruments can detect wildfires and can send vital data about the size and location to land managers. These satellites and technology are crucial to understanding how wildfires spread, the range and direction of the smoke direction, and how the fires impact the ecosystems. 

“NASA's satellite, airborne and field research capture the full impact of fires in the Earth system, from rapid detection of actively burning fires, transport of smoke and changes in ecosystems in the days to decades following fire,” said Doug Morton, a research scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Satellites collect data across the globe several times throughout the day, some as frequently as every five to fifteen minutes.

There are two different types of satellites that monitor the Earth and send data back. First is the polar orbiters that can take detailed looks of views and smoke around the world, and second are the geostationary satellites. 

There are dozens of instruments that help specifically with monitoring and analyzing fires, and this data is critical to disaster response efforts. 

The Atmospheric Infrared Sounder (AIRS) instrument collects data on carbon monoxide concentrations and pollution from burning fires. 

The Multi-angle Imaging Spectroradiometer (MISR) instrument focuses on smoke plumes, as measuring their height can then dictate how far the smoke will travel in the atmosphere. 

Other instruments can provide both visible imageries during the day and infrared imagery at night, with thermal detectors that reveal fire hotspots that are actively burning, their smoke plumes, and heat signatures from the fires. 

Temperature, smoke plumage, pollution from smoke particles, location, and the extent of damage are all necessary to understanding, combating, and preventing fires across the globe, and NASA instruments provide crucial data to accomplish this task.

The world’s coral reefs are facing critical challenges from the growing threat of climate change and bleaching. But now, a new study from <a href="https://www.cornell.edu/">Cornell University</a> has revealed that plastic trash is further distressing corals by making them 20 times more susceptible to tissue loss and disease.

“Plastic debris acts like a marine motorhome for microbes,” said study lead author Joleah Lamb. “Plastics make ideal vessels for colonizing microscopic organisms that could trigger disease if they come into contact with corals.”

“Plastic items - commonly made of polypropylene, such as bottle caps and toothbrushes - have been shown to become heavily inhabited by bacteria. This is associated with the globally devastating group of coral diseases known as white syndromes.”

The researchers have found that the likelihood of disease increases from four to 89 percent when <a href="https://www.earth.com/news/theresa-may-plastic-plan/">plastic</a> debris meets coral. According to the experts, around 11.1 billion plastic items are entangled on reefs across the Asia-Pacific region. They predicted that this amount will increase by 40 percent over the next seven years.

Corals are essentially animals with living tissue that build upon one another and form reefs. Plastics contain bacterial pathogens  that disrupt fragile coral tissues and their microbiome.

“What's troubling about coral disease is that once the coral tissue loss occurs, it's not coming back,” explained Lamb. “It's like getting gangrene on your foot and there is nothing you can do to stop it from affecting your whole body.”

The study was focused on 159 coral reefs in Indonesia, Australia, Myanmar, and Thailand. The researchers visually monitored the reefs to look for tissue loss and disease lesions. The presence of plastic debris ranged from 0.4 items per 100 square meters in Australia to 25.6 items per 100 square meters in Indonesia. 

Lamb pointed out that approximately 4.8 to 12.7 million metric tons of plastic waste ends up in the ocean every year. According to the researchers, the amount of plastic waste on coral reefs will increase to around 15.7 billion items by 2025. This amount of debris has the potential to cause skeletal eroding band disease, white syndromes, and black band disease.

“Our work shows that plastic pollution is killing corals,” said senior author Drew Harvell. “Our goal is to focus less on measuring things dying and more on finding solutions. While we can't stop the huge impact of global warming on coral health in the short term, this new work should drive policy toward reducing plastic pollution.”

The study is published in the journal <a href="http://www.sciencemag.org/">Science</a>.

<h2 class="wp-block-heading" id="h-invisible-threat-in-urban-air">Invisible threat in urban air</h2>



City dwellers face an unseen danger with every breath. New findings from Emory University researchers suggest that fine particulate matter from <a href="http://earth.com/news/traffic-related-air-pollution-might-increase-alzheimers-risk/" target="_blank" rel="noreferrer noopener">vehicle emissions may significantly elevate the risk of developing Alzheimer's disease</a>. The study examined brain tissue samples from 224 individuals who had confirmed diagnoses and volunteered their brains for scientific research.



<h2 class="wp-block-heading" id="h-disturbing-connections-emerge">Disturbing connections emerge</h2>



Scientists analyzed neuritic plaques — protein clusters that characterize Alzheimer's — while mapping each participant's exposure to PM2.5 particles based on residential location and surrounding traffic density. The correlation proved more alarming than anticipated. Individuals experiencing higher pollution exposure showed nearly double the likelihood of elevated plaque accumulation in brain tissue.



<h2 class="wp-block-heading" id="h-timing-matters">Timing matters</h2>



The research team discovered that pollution exposure during the final year before death demonstrated the strongest association with brain changes. This timeline suggests relatively rapid impacts from environmental toxins on neural health. The connection remained robust even after accounting for various demographic and health factors.



<h2 class="wp-block-heading" id="h-genetic-vulnerability-patterns">Genetic vulnerability patterns</h2>



Perhaps most concerning, people lacking the APOE gene—which naturally predisposes individuals to Alzheimer's — exhibited more than twice the susceptibility to pollution-related brain damage. Study author Dr. Anke Huels noted this indicates environmental elements like air contamination could trigger the disease in cases where hereditary factors don't explain.



<h2 class="wp-block-heading" id="h-public-health-implications">Public health implications</h2>



These findings, published in <a href="https://www.neurology.org/" target="_blank" rel="noreferrer noopener">Neurology</a>, underscore the critical importance of air quality regulations in urban planning. The research suggests that implementing stricter emission controls and promoting alternative transportation could serve as powerful tools in Alzheimer's prevention.



As cities worldwide grapple with growing traffic congestion and aging populations, this study highlights an urgent need for comprehensive approaches to environmental health that protect both our lungs and our minds.

<h2 class="wp-block-heading" id="h-hidden-waters-beneath-ancient-craters">Hidden waters beneath ancient craters</h2>



Scientists have made a startling discovery that challenges everything we thought we knew about <a href="https://www.earth.com/news/saturn-moon-mimas-has-remarkably-young-ocean/" target="_blank" rel="noreferrer noopener">Saturn's moon Mimas</a>. Beneath the heavily cratered surface that earned it the nickname "Death Star" lies a global ocean that formed just 5 to 15 million years ago—a remarkably young age by cosmic standards.



<h2 class="wp-block-heading" id="h-cassini-data-reveals-orbital-secrets">Cassini data reveals orbital secrets</h2>



The discovery, led by Dr. Valéry Lainey of the <a href="https://observatoiredeparis.psl.eu/" target="_blank" rel="noreferrer noopener">Observatoire de Paris</a>, emerged from careful analysis of <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>'s Cassini spacecraft data. By studying subtle irregularities in Mimas's orbit around Saturn, researchers detected the gravitational signature of liquid water hidden 20 to 30 kilometers beneath the moon's icy shell.



<h2 class="wp-block-heading" id="h-an-unlikely-ocean-world">An unlikely ocean world</h2>



At only 400 kilometers in diameter, Mimas seemed like the least likely candidate to harbor a subsurface ocean. Unlike other ocean moons such as Europa and Enceladus, which show clear surface signs of internal activity, Mimas displays no obvious hints of the liquid water beneath its ancient, crater-scarred exterior.



"Mimas is a small moon, and its heavily cratered surface gave no hint of the hidden ocean beneath," explained Dr. Nick Cooper from <a href="https://www.qmul.ac.uk/" target="_blank" rel="noreferrer noopener">Queen Mary University of London</a>, a study co-author.



<h2 class="wp-block-heading" id="h-implications-for-astrobiology">Implications for astrobiology</h2>



The ocean's recent formation makes Mimas a prime target for studying how oceans develop and potentially support life. This discovery adds another member to the exclusive club of ocean worlds in our solar system, each offering unique insights into the conditions necessary for habitability.



The research, published in <a href="https://www.nature.com/" target="_blank" rel="noreferrer noopener">Nature</a> journal, demonstrates how advanced orbital analysis can reveal hidden features of celestial bodies, opening new possibilities for understanding ocean formation throughout the cosmos.

<h2 class="wp-block-heading" id="h-when-earth-became-a-frozen-wasteland">When Earth became a frozen wasteland</h2>



Imagine Earth as a giant snowball, frozen solid from the North Pole to the equator. This wasn't the plot of a science fiction movie – it was our planet's reality 700 million years ago during an extreme ice age that has puzzled scientists for decades.



<h2 class="wp-block-heading" id="h-the-discovery">The discovery</h2>



Australian researchers from the <a href="https://www.sydney.edu.au/" target="_blank" rel="noreferrer noopener">University of Sydney</a> have finally cracked one of geology's greatest mysteries: what caused the Sturtian glaciation and why it persisted for an unprecedented 57 million years. This period occurred long before dinosaurs roamed the Earth, when no complex plants or multicellular animals existed.



Dr. Adriana Dutkiewicz, the study's lead author, describes a world completely unlike today's climate. "Imagine the Earth almost completely frozen over," she explained. "The planet was blanketed in ice from poles to equator, and temperatures plunged."



<h2 class="wp-block-heading" id="h-the-combination-of-climate-factors">The combination of climate factors</h2>



The research team discovered that this massive freeze resulted from a "double whammy" of geological events. First, plate tectonic activity reduced volcanic carbon dioxide emissions to historically low levels. Volcanic activity typically releases CO2 into the atmosphere, creating a greenhouse effect that keeps Earth warm.



Simultaneously, weathering of volcanic rocks in what is now Canada actively absorbed atmospheric CO2, further reducing greenhouse gas concentrations. When atmospheric carbon dioxide levels dropped below 200 parts per million – less than half of today's levels – glaciation engulfed the entire planet.



<h2 class="wp-block-heading" id="h-modern-climate-implications">Modern climate implications</h2>



Published in the journal <a href="https://pubs.geoscienceworld.org/geology" target="_blank" rel="noreferrer noopener">Geology</a>, this research provides crucial insights into Earth's climate system. While geological climate changes occur over millions of years, the study emphasizes that human-induced climate change is happening at a pace ten times faster than previously observed natural changes, highlighting the urgent need to understand our planet's delicate climate balance.

<h2 class="wp-block-heading" id="h-a-contrasting-climate-response">A contrasting climate response</h2>



Most coastal towns are <a href="https://www.earth.com/news/sinking-land-will-intensify-the-effects-of-rising-sea-levels/" target="_blank" rel="noreferrer noopener">preparing for higher sea levels</a>, but <a href="https://www.earth.com/news/greenland-no-longer-has-to-worry-about-rising-sea-levels/" target="_blank" rel="noreferrer noopener">Greenland presents</a> a different scenario during climate change. The ground there is rising at a remarkable rate. Over the past decade, some areas have lifted about 20 centimeters, which translates to roughly 2 meters per century. This rate significantly exceeds current projections for sea level rise.



<h2 class="wp-block-heading" id="h-geological-rebound-process-through-climate-change">Geological rebound process through climate change</h2>



The mechanism behind this phenomenon is straightforward. As the ice sheet melts, the immense weight is removed from the bedrock, causing the land to rebound upward. This process resembles the way compressed material springs back when pressure is released.



<h2 class="wp-block-heading" id="h-scientific-monitoring-networks">Scientific monitoring networks</h2>



Researchers at the <a href="https://www.dtu.dk/english/" target="_blank" rel="noreferrer noopener">Technical University of Denmark</a> are documenting this uplift using the GNET network, consisting of 61 GPS stations positioned around Greenland's coast. These sensors can detect movement with millimeter precision, providing detailed measurements of the ongoing changes.



The data reveal that current uplift rates exceed the gradual rebound occurring since the last ice age ended approximately 12,000 years ago. This acceleration corresponds directly with increased ice sheet melting rates.



<h2 class="wp-block-heading" id="h-coastal-transformation">Coastal Transformation</h2>



This uplift is actively reshaping Greenland's coastline. New islands and rocky formations, called "skerries," are emerging as previously submerged land surfaces rise above the water level. This represents a notable contrast to global concerns about rising seas.



The study, published in Geophysical Research Letters, demonstrates the varied regional impacts of climate change. While many locations face rising water levels, Greenland's bedrock is literally rising above the surrounding seas.



The full study was recently published in <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2023GL104851" target="_blank" rel="noreferrer noopener">Geophysical Research Letters</a>.

<h2 class="wp-block-heading" id="h-ai-agent-training-transforms-the-workplace-fear-factor-into-a-competitive-advantage">AI agent training transforms the workplace 'fear factor' into a competitive advantage</h2>



Organizations that offer comprehensive artificial intelligence training to their workers find remarkable value that extends well beyond basic <a href="https://www.earth.com/news/mind-wandering-might-be-more-productive-than-you-think/" target="_blank" rel="noreferrer noopener">productivity improvements</a>. Emerging research demonstrates that carefully crafted AI training programs <a href="https://www.earth.com/news/ai-does-not-replace-human-creativity-but-enhances-it/" target="_blank" rel="noreferrer noopener">enhance</a> corporate performance, lower operational costs, and dramatically improve employee psychological well-being by turning workplace uncertainty into professional empowerment.



<h2 class="wp-block-heading" id="h-addressing-the-widespread-ai-anxiety-crisis-among-us">Addressing the widespread 'AI anxiety' crisis among us</h2>



A staggering 53% of employees expressed concern that the use of AI tools to automate work tasks could make them appear disposable to their employers, according to <a href="https://www.microsoft.com/" target="_blank" rel="noreferrer noopener">Microsoft</a>'s 2024 workplace survey. Such pervasive worry about being substituted by machines has caused what researchers have termed "AI technostress" – a psychological state that can result in occupational burnout and poorer mental well-being.



Data published in <a href="https://www.nature.com/palcomms/" target="_blank" rel="noreferrer noopener">Humanities and Social Sciences Communications</a> showed that belief in AI learning ability was a moderator in the link between technology adoption and work pressure, and higher confidence significantly lowered negative psychological responses. Workers provided ample training to become competent with AI software have significantly lower stress.



Companies like <a href="https://www.mindstudio.ai/" target="_blank" rel="noreferrer noopener">MindStudio</a> have platforms for building what are known as "AI Agents". In essence, AI Agents are simply tools that employees can build for themselves or their teams quickly and inexpensively. MindStudio will even train entire companies, from the CEO on down, at no cost. By letting MindStudio empower employees, companies avoid hiring more IT staff, buying more software, and implementing solutions to problems that do not exist.



MindStudio even has partners locally for companies, like <a href="http://www.dominnus.com" target="_blank" rel="noreferrer noopener">Dominnus</a> with offices in the Carolinas, California, and Denver, to help build AI Agents and support employees as they become resident AI experts for their organization. The training provided by MindStudio is applicable across other AI Agent building platforms as well.



<h2 class="wp-block-heading" id="h-revolutionary-productivity-through-focused-learning">Revolutionary productivity through focused learning</h2>



Organizations that implement large-scale AI training programs achieve dramatic outcomes. Employees performed tasks significantly better when they utilized AI support compared to when they didn't, according to <a href="https://www.nngroup.com/" target="_blank" rel="noreferrer noopener">Nielsen Norman Group</a> research findings. Their study documented productivity increases of 66% for a variety of professional tasks.



Federal Reserve Bank of St. Louis research finds workers record 33% higher productivity in time working with generative AI tools. The benefit is equivalent to 5.4% of work time savings for AI users – around 2.2 hours per week for full-time workers.



<h2 class="wp-block-heading" id="h-psychological-well-being-benefits-through-ai-competence">Psychological well-being benefits through AI competence</h2>



The emotional transformation when employees are provided with proper technology training is a fundamental transformation from fear to professional confidence. A survey of 600 employees across industries, carried out by ScienceDirect, proved that AI capabilities strengthen work environment commitment and improve job satisfaction.



A <a href="https://www.lut.fi/en" target="_blank" rel="noreferrer noopener">LUT University</a> study discovered that AI adoption has no direct effect on workers' well-being but does so indirectly through working conditions like task optimization and safety protocols. Strategically deployed AI that involves correct training can actually increase workplace mental well-being.



<h2 class="wp-block-heading" id="h-from-replacement-anxiety-to-partnership-confidence">From 'replacement anxiety' to 'partnership confidence'</h2>



Although 35% of those interviewed in recent McKinsey studies were concerned about workforce displacement, firms with large-scale training initiatives witness such fears dissipate quickly. The World Economic Forum found that two out of three respondents believe AI competencies will enhance their career prospects and job marketability.



This shift from fear to trust has measurable implications for job satisfaction. Applied Sciences research indicates AI can create tailored wellness programs based on individual employee requirements.



<h2 class="wp-block-heading" id="h-financial-benefits-of-increased-retention">Financial benefits of increased retention</h2>



The mental health advantages of AI learning have a direct impact on organizational bottom lines in the form of a positive feedback cycle with high retention of employees. Recent ROI research validates that artificial intelligence learning has a beneficial impact on employee turnover and satisfaction levels.



PriceWaterhouseCoopers' research documents 20% to 30% improvements in productivity, market speed, and revenue in organizations that attempt systematic AI adoption through comprehensive training.



<h2 class="wp-block-heading" id="h-environmental-advantages-of-ai-enabled-teams">Environmental advantages of AI-enabled teams</h2>



AI training has unforeseen environmental benefits as it makes the work environment more efficient. According to a study in Scientific Reports, the carbon footprint in writing and illustrating work is significantly lower when AI performs it compared to humans. AI software produces 130 to 1,500 times less CO2 equivalent per page of text created than human authors.



In addition, AI-driven remote work functionality significantly reduces environmental impact. Research by Cornell University and Microsoft indicates that remote workers reduce greenhouse gas emissions by up to 54% by not commuting daily to offices. Hybrid workers working remotely two to four days a week can reduce their carbon footprint by 11% to 29%.



<h2 class="wp-block-heading" id="h-cumulative-organizational-advantages">Cumulative organizational advantages</h2>



The compounding gains of better mental well-being, reduced turnover, increased productivity, and environmental benefits flow to enterprises from the pairing. McKinsey analysis estimates the long-term AI potential at $4.4 trillion in incremental productivity growth opportunity from business use cases.



As of now, 75% of knowledge workers globally utilize generative AI, mirroring widespread adoption patterns. Organizations that provide organized training and assistance see the most favorable results in productivity, worker satisfaction, and ecological sustainability.



The research overwhelmingly indicates that companies that invest in proper AI education, like that offered through <a href="https://www.mindstudio.ai" target="_blank" rel="noreferrer noopener">MindStudio</a>, establish win-win scenarios where employees are both more empowered and less stressed, and companies enjoy the gains of increased productivity, reduced turnover, and improved mental health outcomes throughout their workforce.

<h2 class="wp-block-heading" id="h-a-natural-solution-to-disease-through-crop-modification">A natural solution to disease through crop modification.</h2>



The agricultural industry stands at a crossroads between productivity and environmental responsibility, and crop modification often carries a negative connotation. While chemical pesticides have long been the go-to solution for crop protection, their harmful effects on ecosystems and human health have prompted scientists to seek alternatives. The recent breakthrough by <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> researchers offers a promising path forward through the precise manipulation of plant-associated microbial communities.



<h2 class="wp-block-heading" id="h-the-science-behind-microbial-partnerships">The science behind microbial partnerships</h2>



Plants naturally harbor diverse ecosystems of bacteria, fungi, and other microorganisms that function as biological allies. These microscopic partners contribute to disease resistance, nutrient absorption, and stress tolerance. However, until now, scientists lacked the tools to deliberately reshape these communities to enhance crop protection.



The Southampton team's approach centered on <a href="https://www.earth.com/news/engineered-plant-microbiomes-the-future-of-crop-protection/" target="_blank" rel="noreferrer noopener">modifying lignin biosynthesis genes in rice plants</a>. This strategic intervention altered the plant's metabolic output, creating conditions that favored beneficial bacterial populations while suppressing harmful ones. The result was a living defense system embedded within the plant itself.



<h2 class="wp-block-heading" id="h-implications-for-global-food-security">Implications for global food security</h2>



The successful demonstration against Xanthomonas oryzae, the pathogen responsible for bacterial blight in rice, represents more than a laboratory achievement. Rice feeds nearly half the world's population, and bacterial blight causes devastating crop losses annually. Traditional control methods rely heavily on pesticides that contaminate soil and water systems.



<h2 class="wp-block-heading" id="h-looking-beyond-disease-resistance">Looking Beyond Disease Resistance</h2>



While disease protection represents the immediate application, the research framework opens doors to broader agricultural improvements. Future developments could engineer microbiomes to enhance nutrient uptake, reducing dependence on synthetic fertilizers. This dual benefit addresses both crop productivity and environmental sustainability.



<h2 class="wp-block-heading" id="h-the-path-forward">The path forward</h2>



As this technology advances from laboratory to field applications, it promises to reshape sustainable agriculture. The ability to program plants with their own biological defense systems could herald a new era where crops protect themselves naturally, reducing chemical inputs while maintaining yields necessary for global food security.

<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?



The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.



<h2 class="wp-block-heading">What was acid rain?</h2>



Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.



<h2 class="wp-block-heading">The science behind it</h2>



Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.



While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.



<h2 class="wp-block-heading">The crisis at its peak</h2>



During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.



<h2 class="wp-block-heading">Environmental devastation</h2>



The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.



By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.



Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.



<h2 class="wp-block-heading">Economic impact</h2>



Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.



<h2 class="wp-block-heading">The solution: government action and technology</h2>



Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.



<h2 class="wp-block-heading">The Clean Air Act of 1990</h2>



The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.



<h2 class="wp-block-heading">Cap-and-trade success</h2>



Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.



The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.



<h2 class="wp-block-heading">Technology advances</h2>



Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.



The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today">Why we don't hear about it today</h2>



Why did acid rain disappear from headlines? Simple: the problem was largely solved.



<h2 class="wp-block-heading">Success doesn't make news</h2>



There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.



<h2 class="wp-block-heading">Mission accomplished</h2>



The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.



<h2 class="wp-block-heading" id="h-is-it-really-gone">Is it really gone?</h2>



The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.



EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.



<h2 class="wp-block-heading">What this teaches us</h2>



The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.



Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.



<h2 class="wp-block-heading">Conclusion</h2>



Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.



Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.



This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.



Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.

<h2 class="wp-block-heading">Frequently Asked Questions</h2>



1. Is acid rain completely gone? No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.



2. How long did solving take? Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.



3. What made the solution successful? Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.



4. Do other countries have acid rain problems? Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.



5. Could acid rain return? Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.



6. Can you recommend any teaching tools on the subject of "acid rain"? The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a>

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</a>.

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes how record-breaking heat expressed itself around the world in 2022.



Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes how Earth is unique in our solar system for its ability to sustain liquid water on its surface. But now, the water cycle is shifting as the climate warms, and scientists must find ways to predict how these changes will affect water availability.



Overall, 96 percent of Earth's water is saltwater, and nearly all of freshwater is found in ice and groundwater. These sources of water are linked as it passes through solid, liquid and gas phases.



In a warmer climate, the water cycle will be transformed. It will be easier for water to evaporate and form clouds, and storms will become more frequent and intense. Some regions will get too much water, while others will be left without enough water. In addition, soil moisture will be lost - which threatens food security.



Scientists are using satellite data from over the last 40 years to track changes that are happening in the water cycle. This will ultimately help us prepare for extreme events and better manage our water resources, according to ESA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard Space Flight Center</a> features images of Saturn from NASA’s Hubble Space Telescope. The photographs capture the start of the mysterious "spoke season" on Saturn - when unexplained features appear on its rings. 



According to NASA, both the cause of the spokes and their seasonal variability have yet to be fully explained by planetary scientists.



"Like Earth, Saturn is tilted on its axis and therefore has four seasons, though because of Saturn's much larger orbit, each season lasts approximately seven Earth years. Equinox occurs when the rings are tilted edge-on to the Sun," explains NASA.



"The spokes disappear when it is near summer or winter solstice on Saturn. (When the Sun appears to reach either its highest or lowest latitude in the northern or southern hemisphere of a planet.) As the autumnal equinox of Saturn's northern hemisphere on May 6, 2025, draws near, the spokes are expected to become increasingly prominent and observable."



Experts believe that the spokes may be a product of the planet's variable magnetic field. When magnetic fields interact with solar wind, an electrically charged environment is created. This phenomenon is visible on Earth as the northern lights.&nbsp;



"Scientists think that the smallest, dust-sized icy ring particles can become charged as well, which temporarily levitates those particles above the rest of the larger icy particles and boulders in the rings," says NASA.



The spokes were first observed in the early 1980s by NASA's Voyager mission. Depending on the angle of the rings, the spokes can appear dark or light.



"Thanks to Hubble's OPAL program, which is building an archive of data on the outer solar system planets, we will have longer dedicated time to study Saturn’s spokes this season than ever before," said NASA senior planetary scientist Amy Simon, head of the Hubble Outer Planet Atmospheres Legacy (OPAL) program.



"Despite years of excellent observations by the Cassini mission, the precise beginning and duration of the spoke season is still unpredictable, rather like predicting the first storm during hurricane season."
