Balancing cleaner air with rising incomes is not a luxury question for developing countries. It is a real-world, and real-life, policy problem that shapes health, jobs, and the future of their cities.



A new <a href="https://www.worldscientific.com/doi/10.1142/S0217590825500304" target="_blank" rel="noreferrer noopener">study</a> lays out when zero emissions can go hand in hand with steady <a href="https://www.earth.com/news/rising-temperatures-will-cut-world-gdp-by-a-staggering-40-percent-if-nothing-changes/">growth</a>, even when governments rely on foreign aid.



<h2 class="wp-block-heading" id="h-zero-emissions-and-economic-growth">Zero emissions and economic growth</h2>



The work comes from <a href="https://tus.elsevierpure.com/en/persons/hideo-noda" target="_blank" rel="noreferrer noopener">Hideo Noda</a> at the Tokyo University of Science (<a href="https://www.tus.ac.jp/en/" target="_blank" rel="noreferrer noopener">TUS</a>) with coauthor Fengqi Fang, a Ph.D. candidate in Business Administration from the Graduate School of Business Administration at TUS. 



The team builds a simple but testable way to check if a country can hit zero net <a href="https://www.earth.com/news/global-trade-is-fueling-a-dangerous-rise-in-methane-emissions/">emissions</a> while its economy keeps expanding.



They also verify the model numerically using real world style parameters so it is not just a chalkboard exercise. 



The paper connects theory to a specific United Nations target on decoupling growth from <a href="https://www.earth.com/news/limiting-global-warming-to-1-5c-is-almost-certainly-out-of-reach/">environmental damage</a>.



<h2 class="wp-block-heading" id="h-zero-emissions-models">Zero emissions models</h2>



First, the authors define a zero-emissions <a href="https://www.un.org/en/climatechange/net-zero-coalition" target="_blank" rel="noreferrer noopener">policy</a> as keeping net pollution at zero at every point in time, by matching abatement to emissions. That requires money, technology, and clear rules to assign who pays.



They run two versions of the economy. 



One is a public goods <a href="https://scholar.harvard.edu/files/stantcheva/files/lecture8.pdf" target="_blank" rel="noreferrer noopener">model</a> where government services like roads or schools lift private production for everyone at once, a standard growth <a href="https://www.journals.uchicago.edu/doi/10.1086/261726" target="_blank" rel="noreferrer noopener">model</a> introduced by Robert Barro in 1990. 



The second adds <a href="https://www.earth.com/news/where-will-climate-change-hit-hardest-global-index-reveals-vulnerability/">congestion</a>, where more people share the same public services so the boost per person shrinks.



<h2 class="wp-block-heading" id="h-minimum-income-rule">Minimum income rule</h2>



The key test is whether gross domestic product (<a href="https://data.worldbank.org/indicator/NY.GDP.PCAP.CD" target="_blank" rel="noreferrer noopener">GDP</a>) per capita rises above a minimum income threshold so a country can fully clean what it emits. 



The authors call this the kindergarten rule level of abatement, as in: “clean-up what you make dirty.”



"Following the Kindergarten rule means implementing zero emission technologies in either finite time or asymptotically," noted M. Scott Taylor and William Brock in their related <a href="https://www.nber.org/papers/w9597" target="_blank" rel="noreferrer noopener">study</a>. 



This frame anchors the new threshold concept for developing countries.



<h2 class="wp-block-heading" id="h-aid-supports-clean-income-growth">Aid supports clean income growth</h2>



Many low income governments fund services with official development assistance (<a href="https://www.oecd.org/en/topics/policy-issues/official-development-assistance-oda.html" target="_blank" rel="noreferrer noopener">ODA</a>), so the model lets outside aid pay for both cleaning and public services. 



That design reflects classic work showing how aid aimed at productive public services can shift long run growth.



In related <a href="https://www.sciencedirect.com/science/article/abs/pii/S0304387806000290" target="_blank" rel="noreferrer noopener">theory</a>, flexible labor and aid tied to public capital influence the path of output and welfare. The new paper extends this logic to pollution control that must be paid for every year.



<h2 class="wp-block-heading" id="h-changing-income-threshold">Changing income threshold</h2>



The threshold depends on clean technology, population size, and how much aid is fixed to environmental <a href="https://www.earth.com/news/expanding-oil-and-gas-fields-threaten-global-climate-goals/">uses</a>. Better abatement technology lowers the income bar because each dollar of cleanup removes more pollution.



Population matters differently across the two models. In the public goods case, a larger labor force can raise growth because services scale with the economy, while in the congestion case that scale effect drops out as services get diluted.



<h2 class="wp-block-heading" id="h-taxes-and-zero-emissions-targets">Taxes and zero emissions targets</h2>



The model also looks at tax policy, focusing on a labor income tax that finances services. 



There is a tax rate that maximizes the growth of income per person, and under both models governments can reach the needed income threshold in finite time if they choose that growth maximizing rate.



Public services that complement private capital are the link. When governments tax and spend on those services efficiently, private firms produce more and the <a href="https://www.earth.com/news/climate-action-economies-can-grow-while-cutting-emissions/">economy climbs</a> to the income level that makes full abatement feasible.



"Both models indicate that implementing the zero-emissions policy is compatible with sustainable economic growth," wrote Noda. 



They also show the kindergarten rule threshold is higher with congestion than without it, so crowding of public services slows the crossing.



"We call this threshold the kindergarten rule level of pollution abatement in terms of GDP per capita," wrote Noda. The result gives policymakers a clear income target, not just a slogan about decoupling.



<h2 class="wp-block-heading" id="h-income-growth-and-sdgs">Income growth and SDGs</h2>



Target 8.4 of the Sustainable Development Goals (<a href="https://www.undp.org/sustainable-development-goals" target="_blank" rel="noreferrer noopener">SDGs</a>) asks countries to decouple growth from environmental degradation. 



The authors argue their framework helps explain when that is possible in practice, and how policy levers change the timing.



The UN defines the <a href="https://metadata.un.org/sdg/8.4" target="_blank" rel="noreferrer noopener">target</a> as improving resource efficiency and decoupling growth from environmental harm through 2030. The paper’s threshold view fits that mandate with a concrete yardstick.



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



Earlier <a href="https://www.sciencedirect.com/science/article/abs/pii/S0959652621009112" target="_blank" rel="noreferrer noopener">work</a> in the same research stream focused on developed, innovation-driven economies and showed that zero emissions could be achieved alongside continued growth. 



That study examined whether sustained economic expansion could occur while also maintaining <a href="https://www.earth.com/news/a-net-zero-world-will-require-75-trillion-of-investment-and-1-billion-electric-cars/">zero net pollution emissions</a>.



The new paper shows the same compatibility can hold in aid dependent settings where innovation is not the main growth engine. 



That extension fills a real gap, because many low income countries face tighter fiscal and technological limits.



Build or buy cleaner technology so the threshold falls. Treat tied aid for environmental programs as a growth tool and not just a cost center.



Set tax policy to raise the growth rate of income per person, then sustain it long enough to pass the threshold. Guard against congestion by scaling services with population, so gains are not diluted.



The study is published in <a href="https://www.worldscientific.com/doi/10.1142/S0217590825500304" target="_blank" rel="noreferrer noopener">The Singapore Economic Review</a>.

Food Industry CEOs Call For <a href="https://www.bing.com/search?q=climate&amp;cvid=f3b80f2934dc40ecb5a0ac9f83350268&amp;FORM=ANAB01&amp;PC=HCTS">Climate</a> Change Deal. The CEOs of several major food and beverage companies are calling on world leaders to push for a meaningful agreement at the United Nation's conference on climate change later this year in Paris.
The 10 companies, including cereal maker General Mills and candy maker Mars Inc., will run an open letter as a full-page ad in the Financial Times and Washington Post on Thursday. They say they will "re-energize" their own efforts to make their supply chains more sustainable as well.
"We are asking you to embrace the opportunity presented to you in <a href="https://www.earth.com/news/inconsistent-paris-agreement-pledges/">Paris</a>, and to come back with a sound agreement, properly financed, that can affect real change," the open letter reads.

EPA Sets Toxic Pollution Limits For Waterways. The Environmental Protection Agency on Wednesday imposed new standards for mercury, lead and other <a href="https://www.bing.com/search?q=toxic&amp;cvid=9a03b90642464f0b80c2ae680e25b294&amp;FORM=ANAB01&amp;PC=HCTS">toxic</a> pollutants that are discharged into the nation's rivers and streams from steam electric power plants.
If exposed at high levels, the pollutants can cause neurological damage in children, lead to cancer and damage the circulatory system, kidneys and livers. EPA Sets Toxic Pollution Limits For Waterways
EPA Administrator Gina McCarthy said the rules, the first national limits on <a href="https://www.earth.com/news/honey-trace-environmental-pollutants/">pollutants</a> from coal-fired steam electricity plants, "will provide significant protections for our children and communities across the country, including minority and low-income communities, from exposure to pollutants that can cause ... serious health problems."
The rule will remove 1.4 billion pounds a year of toxic metals discharged nationwide, including mercury, arsenic, lead and selenium, the EPA said.
The EPA said most of the nation's 1,080 steam electric power plants already meet the requirements. About 12 percent, or 134 plants, will have to make new investments to meet the new rules, including dozens of plants across the South and Midwest.
More than 23,000 miles of rivers and streams across the country are polluted by steam electric discharges, which occur close to 100 public drinking water intakes and nearly 2,000 public wells across the nation, the EPA said.
Toxic metals do not break down in the environment and can contaminate sediment in waterways and harm aquatic life and wildlife, including killing large numbers of fish. Steam electric power plants account for about 30 percent of all toxic pollutants discharged into streams, rivers and lakes from U.S. industrial facilities.
The new standards come as Duke Energy agreed Tuesday to pay North Carolina regulators $7 million to settle allegations of groundwater pollution at its coal ash pits and to perform accelerated cleanups costing millions of dollars at four sites. Coal ash is the waste left after coal is burned to generate electricity and contains toxic heavy metals including arsenic and mercury.
Duke agreed in May to plead guilty to nine criminal violations of the federal Clean Water Act and pay more than $102 million in fines and restitution for failing to contain water contaminated by coal residues at five North Carolina coal-burning plants. A massive spill at a Duke coal ash pond in Eden, N.C., coated 70 miles of the Dan River in gray sludge in 2014.
The wastewater rule is one of three major actions expected this week as the EPA announces a flurry of new rules intended to reduce air and water pollution.
On Tuesday, the agency set new rules to reduce toxic air pollution from oil refineries by forcing operators to adopt new technology that better monitors and controls emissions. The rules will require for the first time that refineries install air monitors along "fence lines" where benzene and other toxic emissions enter neighboring communities.
The EPA faces a court-ordered deadline of Thursday to set a new limit on smog-forming pollution linked to asthma and respiratory illness. Officials are expected to set an ozone limit of 70 parts per billion or less in the atmosphere, down from the existing standard of 75.

Officials: California Is Meeting Water Conservation Targets. A state water official said Californians have met a water conservation target for a third consecutive month during the grinding drought.
The State Water Resources Control Board on Thursday will release statewide conservation figures for August.
Max Gomberg, a senior climate scientist for the board, declined to provide specific figures ahead of the announcement but said he expects the results to meet the 25 percent savings goal set by Gov. Jerry Brown. Officials: California Is Meeting Water Conservation Targets
However, Gomberg warned that Californians can't allow themselves to be distracted by the hype of a coming El Nino weather pattern that has raised hopes that it will break California's four-year drought.
He said an El Nino doesn't guarantee a wet winter for<a href="https://www.bing.com/search?q=california&amp;cvid=6eed2d58f00e47cda9420ca2a2028cde&amp;FORM=ANAB01&amp;PC=HCTS"> California</a> and urged people to keep saving water.
"We need to continue the conservation efforts," he said. "People need to keep on doing what they've been doing."
The state reported savings of 27 percent in June and 31 percent in July.
The board also is expected to release figures for August showing how each community is performing. The mandate by Brown gave each city an individual conservation target based on water use in the same month of 2013, the year before Brown declared a drought emergency.
Some of the state's largest cities contacted independently reported meeting their mandates.
Officials in Los Angeles said the city saw savings of 17 percent in August, beating its target of 16 percent. Fresno reported a 28 percent drop, hitting its requirement. Water use in San Diego was 21 percent lower, exceeding its mandated cutback of 16 percent.
State officials said they are working with cities and water districts that have failed to meet targeted cuts.
Gomberg said climate change - signaled by warmer temperatures, a low snowpack and intense wildfires - has made water conservation an ongoing effort.
"Climate change is not something that's happening in the future," Gomberg said. "California is already dealing with the impacts."

India Pledges To Slash Carbon Emissions By 35 Percent. As the last major economy to submit a target for a global climate pact, India is pledging to reduce the intensity of its carbon emissions and boost the share of electricity produced from sources other than fossil fuels to 40 percent by 2030.
The world's third-largest carbon polluter filed its climate action plan to the <a href="https://www.bing.com/search?q=germany&amp;cvid=16f93c49322b4d40b31515606b375c86&amp;FORM=ANAB01&amp;PC=HCTS">Germany</a>-based U.N. climate secretariat late Thursday, the deadline for pledges before a December conference in Paris, where governments are supposed to adopt a landmark deal to fight climate change.
In a 38-page submission citing Mahatma Gandhi, the Indian government said it would slash the rate of emissions relative to gross domestic product by 33-35 percent by 2030 from 2005 levels.
It said India has already reduced its carbon intensity by 12 percent since 2005.
The carbon intensity goal will allow India's emissions to grow as its economy expands, but at a lower rate than now.
"It is estimated that more than half of India of 2030 is yet to be built," the government said.
Environmental groups following the U.N. climate talks welcomed India's pledge.
"India now has positioned itself as a global leader in clean energy, and is poised to play an active and influential role in the international climate negotiations this December," said Rhea Suh, president of the Natural Resources Defense Council, an environmental think tank based in New York.
India plans a fivefold boost in renewable energy capacity in the next five years to 175 gigawatts, including solar power, wind, biomass and small hydropower dams.
Even with a major boost of renewable energy, India is also planning to expand coal power - the biggest source of emissions - to satisfy its energy needs. Coal-fired power plants account for about 60 percent of India's installed power capacity.
By 2030, the government said its installed capacity from "non-fossil fuel based energy resources" would grow to 40 percent. It wasn't immediately clear whether that would also include nuclear power.
India said boosting its renewables to that level would require help with transfer of clean technology and financing - two of the crunch issues before the Paris deal, which is supposed to apply to all countries but also include provisions for rich countries to help poor countries fight climate change and adapt to its consequences.
Scientists say the heat-trapping carbon emissions released by the burning of fossil fuels - coal, oil and gas - are a key driver of rising temperatures that could lead to potentially catastrophic impacts, including flooding of island nations and intensifying droughts.
China and the U.S. are the only countries with higher emissions than India. As a bloc, the 28-nation European Union's emissions are also higher.
Like other developed countries, the U.S. and the EU committed to absolute reduction targets, while China pledged that its emissions would stop growing by 2030. India, with more than 300 million people living in poverty, wasn't expected to offer a peak year because its emissions are projected to increase for decades as energy demand rises along with economic growth.
Indian Environment Minister Prakash Javadekar last week told The Associated Press that developed countries should "vacate the carbon space" to allow India's emissions to increase. "That <a href="http://www.earth.com/news/study-reveals-carbon-cycle-trends-of-the-past-50-million-years/">carbon</a> space demand is climate justice," he said.
Two climate research groups this week said that the pledges put forth before the Paris conference would slow down global warming but projected that temperatures would still rise by 2.7 and 3.5 degrees C (4.9 and 6.3 degrees F), respectively. India Pledges To Slash Carbon Emissions By 35 Percent

Without those cuts, the group calculated that there would be an additional 0.5-1.1 C (0.9-2.0 F) of warming. A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O₃). Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F). The atmospheres of Venus, Mars and Titan also contain greenhouse gases.
Currently, temperatures are about 1.8 C (3.2 F) warmer than in pre-industrial times.

Currently, temperatures are about 1.8 C (3.2 F) warmer than in pre-industrial times. Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. Three isotopes occur naturally, ¹²C and ¹³C being stable, while ¹⁴C is a radionuclide, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.

EPA Sets New Ozone Pollution Standard. The Obama administration on Thursday established stricter limits on the smog-causing pollution linked to asthma and respiratory illness, drawing swift condemnation from business leaders and Republicans who warned of damage to the economy.
The Environmental Protection Agency said the new standard of 70 parts per billion will reduce exposure to dangerous ozone pollution and prevent thousands of <a href="http://www.earth.com/news/fine-particle-pollution-may-cause-children-to-develop-asthma/">asthma</a> attacks and emergency room visits and hundreds of premature deaths each year.
Environmental and health groups argued that the rules fall short. The new standard is below the current standard of 75 parts per billion but at the high end of a range announced by the EPA last fall.
The move fulfills a long-delayed campaign promise by President Barack Obama as he works to cement a legacy on climate change and other environmental policies before leaving office in January 2017. After pledging during his first presidential campaign to tighten ozone limits, Obama backtracked in 2011 by yanking the EPA's proposed ozone limits amid intense pressure from industry and the GOP.
White House spokesman Josh Earnest said Thursday the new ozone rule fits into Obama's strategy to cut pollution while promoting economic growth.
Still, the EPA's long-awaited action set up a fresh confrontation with Republicans already angry about the administration's plans to curb carbon pollution from coal-fired power plants and regulate small streams and wetlands.
Business groups said a new ozone standard is unnecessary and could jeopardize jobs. Environmental and public health groups said the new standard was a step in the right direction but did not go far enough.
EPA Administrator Gina McCarthy acknowledged the intense criticism from all sides, but said her job was to set science-backed standards that protect the health of the American people, not take actions "based on popularity."
In a lengthy statement to reporters, McCarthy said the best available clinical data show that 72 parts per billion "is the lowest ozone exposure that causes adverse health effects in healthy, exercising adults."
From there, she decided to add in a "margin of safety" to protect vulnerable populations, including children, the elderly and those suffering from heart and lung ailments. Setting the level at 70 parts per billion "will essentially eliminate exposures to the levels that clinical studies clearly show are harmful," McCarthy said.
McCarthy said the final judgment was hers, and she aimed to set a standard that was "not too high and not too low. It's very challenging. There's no bright line."
Harold Wimmer, president and CEO of the American Lung Association, said the new standard "simply does not reflect what the science shows is necessary to truly protect public health."
The lung association and other groups have pushed for an ozone limit of 60 parts per billion, saying it would have given Americans much greater health protections. The stricter standard would prevent thousands of premature deaths and nearly 2 million asthma attacks per year, the lung association said.
Business groups also reacted harshly. The National Association of Manufacturers and other groups had lobbied the White House in recent months and spent millions on a TV ad campaign decrying the pending ozone rule as an overreach and a job killer.
"We know that this regulation could have been worse, but it still feels like a punch in the gut," said Tom Riordan, president and CEO of the Wisconsin-based Neenah Enterprises Inc. and task force leader for the manufacturers group.
Riordan said the EPA rule put "politics above job creation" and said manufacturers across the country, especially smaller ones, "will be forced to choose between navigating this rule and hiring new workers, between complying with Washington's mandates and giving raises to their employees."
The rule issued Thursday meets a court-ordered deadline set after public health groups sued in the wake of the administration's 2011 withdrawal of ozone rules.
At least one environmental group vowed to challenge the new standard in court, and business groups said they also were considering a legal challenge.
Cutting ozone emissions to 70 parts per billion would cost industry about $1.4 billion in 2025, the EPA said, far below benefits estimated at $2.9 billion to $5.9 billion annually.
Aiming to smooth the transition, the EPA plans to give states that have the most ozone up to 2037 to come into compliance. But McCarthy said most of the U.S. won't have to take any action, thanks to existing pollution programs and previous EPA limits on pollutants such as mercury and carbon dioxide that have the side benefit of reducing ozone.
The EPA said only 14 U.S. counties would likely fail to meet a standard of 70 parts per billion in 2025, a figure challenged by business groups and Republicans.
The new rules could affect job growth in nearly one-third of the nation's 3,000 counties, said Jack Gerard, president of the American Petroleum Institute, the oil industry's top lobbying group. That's up from 217 counties affected at the current ozone standard, he said.

EPA Sets New Ozone Pollution Standard

EPA Sets New Ozone Pollution Standard. The Obama administration on...

EPA Sets New Ozone Pollution Standard. The Obama administration on Thursday established stricter limits on the smog-causing pollution linked to asthma and respiratory illness, drawing swift condemnation from business leaders and Republicans who warned of damage to the economy.
The Environmental Protection Agency said the new standard of 70 parts per billion will reduce exposure to dangerous ozone pollution and prevent thousands of asthma attacks and emergency room visits and hundreds of premature deaths each year.
Environmental and health groups argued that the rules fall short. The new standard is below the current standard of 75 parts per billion but at the high end of a range announced by the EPA last fall.
The move fulfills a long-delayed campaign promise by President Barack Obama as he works to cement a legacy on climate change and other environmental policies before leaving office in January 2017. After pledging during his first presidential campaign to tighten ozone limits, Obama backtracked in 2011 by yanking the EPA's proposed ozone limits amid intense pressure from industry and the GOP.

India Pledges To Slash Carbon Emissions By 35 Percent. As the last major economy to submit a target for a global climate pact, India is pledging to reduce the intensity of its carbon emissions and boost the share of electricity produced from sources other than fossil fuels to 40 percent by 2030.
The world's third-largest carbon polluter filed its climate action plan to the <a href="https://www.bing.com/search?q=germany&amp;cvid=59ffa7f4d12f4d5e852c6e0459c40a0a&amp;FORM=ANAB01&amp;PC=HCTS">Germany</a>-based U.N. climate secretariat late Thursday, the deadline for pledges before a December conference in Paris, where governments are supposed to adopt a landmark deal to fight climate change.
In a 38-page submission citing Mahatma Gandhi, the <a href="http://www.earth.com/video/indian-ocean-tsunami-reshaped-the-coast-of-sumatra/">Indian</a> government said it would slash the rate of emissions relative to gross domestic product by 33-35 percent by 2030 from 2005 levels.
It said India has already reduced its carbon intensity by 12 percent since 2005.
The carbon intensity goal will allow India's emissions to grow as its economy expands, but at a lower rate than now.
"It is estimated that more than half of India of 2030 is yet to be built," the government said.
Environmental groups following the U.N. climate talks welcomed India's pledge.
"India now has positioned itself as a global leader in clean energy, and is poised to play an active and influential role in the international climate negotiations this December," said Rhea Suh, president of the Natural Resources Defense Council, an environmental think tank based in New York.
India plans a fivefold boost in renewable energy capacity in the next five years to 175 gigawatts, including solar power, wind, biomass and small hydropower dams.
Even with a major boost of renewable energy, India is also planning to expand coal power - the biggest source of emissions - to satisfy its energy needs. Coal-fired power plants account for about 60 percent of India's installed power capacity.
By 2030, the government said its installed capacity from "non-fossil fuel based energy resources" would grow to 40 percent. It wasn't immediately clear whether that would also include nuclear power.
India said boosting its renewables to that level would require help with transfer of clean technology and financing - two of the crunch issues before the Paris deal, which is supposed to apply to all countries but also include provisions for rich countries to help poor countries fight climate change and adapt to its consequences.
Scientists say the heat-trapping carbon emissions released by the burning of fossil fuels - coal, oil and gas - are a key driver of rising temperatures that could lead to potentially catastrophic impacts, including flooding of island nations and intensifying droughts.
China and the U.S. are the only countries with higher emissions than India. As a bloc, the 28-nation European Union's emissions are also higher.
Like other developed countries, the U.S. and the EU committed to absolute reduction targets, while China pledged that its emissions would stop growing by 2030. India, with more than 300 million people living in poverty, wasn't expected to offer a peak year because its emissions are projected to increase for decades as energy demand rises along with economic growth.
Indian Environment Minister Prakash Javadekar last week told The Associated Press that developed countries should "vacate the carbon space" to allow India's emissions to increase. "That carbon space demand is climate justice," he said.
Two climate research groups this week said that the pledges put forth before the Paris conference would slow down global warming but projected that temperatures would still rise by 2.7 and 3.5 degrees C (4.9 and 6.3 degrees F), respectively.

<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.

<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.

Wildlife tunnels save millions of amphibians

https://youtu.be/XYgiPzmNBTU?si=eFYY7gPHU1JznLvU A new long-term study in Monkton, Vermont, reveals that...

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">

</div></figure>



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 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."

Today’s Video of the Day from <a href="http://www.ntu.edu.sg/">NTU Singapore</a> reveals that some plants can remove toxic heavy metals from soil.&nbsp;



The researchers analyzed samples of various tropical plant species to test for levels of heavy metals and metalloids. The study showed that there are existing plants with high levels of these contaminants, which means that these species are great candidates for drawing pollutants out of the soil.&nbsp;



Among the plants examined in the study, 12 species had accumulated several types of heavy metals and metalloids. These plants are widely available, including species that are native to Singapore.



“In a small nation like Singapore, land may be repurposed to support new development plans, so it is important that we have a green and sustainable way to remediate land that is contaminated," said Professor Lam Yeng Ming.



"We set out to uncover how to better make use of tropical plants to do phytoremediation and through advanced characterization techniques, we showed how some of these tropical plant species can be an environmentally friendly and literally a 'green' way to remove contaminants in soil."&nbsp;



"Phytoremediation also has benefits of cost effectiveness, simplicity of management, aesthetic advantages, and long-term applicability and sustainability. The strategy prevents erosion and metal leaching by stabilizing or accumulating heavy metals, so that helps reduce the risk of contaminant spread.”

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes why herbicides are not as effective in killing weeds anymore. In the 20th century, chemical companies developed thousands of herbicides. The most commonly used herbicide was glyphosate, which was introduced in 1974.



Over the past few decades, dozens of species of weeds have evolved resistance to glyphosate. Depending on the site of action, the part of the plant that an herbicide interacts with, weeds may even be resistant to herbicides that have not been developed yet.&nbsp;



With increasing resistance to glyphosate and other herbicides, weeds are - once again - becoming a major concern for farmers.&nbsp;

Today’s Video of the Day from the <a href="https://www.jpl.nasa.gov/">NASA Jet Propulsion Laboratory</a> (JPL) describes a dust storm on Mars that was nearly twice the size of the United States. As the storm covered the southern hemisphere of the planet, some of NASA’s explorers had to delay their normal activities.



NASA’s Insight lander put itself in a "safe mode" for 11 days to conserve battery power because solar power was disrupted by the dust. The Ingenuity Mars Helicopter postponed flights until conditions improved.



"A fleet of NASA orbiters monitor Martian dust storms like this one and serve as lifelines to Earth by relaying data from the rovers and lander on the ground back to the team. This includes the Mars Reconnaissance Orbiter, MAVEN, and Odyssey," reports JPL.



"Dust storms like this recent one start close to the ground and are spread by wind as they rise – warming the cold Martian atmosphere."



The images in the video were captured by NASA’s Curiosity as the dust rolled in. A fleet of orbiters monitored the dust storm from above, relaying data from Mars’ explorers back to scientists on Earth.
