In a setback for environmental protection efforts, recent UN talks failed to produce a concrete plan for addressing worldwide drought concerns. 



The extended discussions highlighted growing rifts between developed and developing nations on how to tackle the drought crisis.



At the United Nations Convention to Combat Desertification (UNCCD) COP16 meeting in Riyadh, delegates from 196 countries and the European Union worked through the night, pushing the talks a day beyond schedule. 



Ibrahim Thiaw, UNCCD Executive Secretary, had expressed high hopes at the start, stating that the world expected negotiators "to adopt a bold decision that can help turn the tide on the most pervasive and the most disruptive environmental disaster: drought."



However, as dawn approached after the night's efforts, Thiaw acknowledged that "parties need more time to agree on the best way forward."



<h2 class="wp-block-heading" id="h-a-pattern-of-failed-environmental-negotiations">A pattern of failed environmental negotiations</h2>



This latest setback follows several recent disappointments that have arisen in global environmental talks, including unsuccessful biodiversity discussions in Colombia and failed <a href="https://www.earth.com/news/how-can-we-combat-the-escalating-plastic-crisis/" target="_blank" rel="noreferrer noopener">plastic pollution</a> negotiations in South Korea.



Tom Mitchell from the <a href="https://www.iied.org/" target="_blank" rel="noreferrer noopener">International Institute for Environment and Development</a> noted that these outcomes have "highlighted the challenges facing global negotiations."



"More than ever, the fractured geopolitical landscape is proving to be a stumbling block to the COP process and some voices are being squeezed out," he added. 



<h2 class="wp-block-heading" id="h-the-real-cost-of-drought-inaction">The real cost of drought inaction</h2>



The stakes couldn't be higher. Droughts, already among the most devastating <a href="https://www.earth.com/news/natural-disasters-are-on-the-rise-but-hazard-plans-are-inadequate/" target="_blank" rel="noreferrer noopener">natural disasters</a>, are expected to intensify due to climate change - threatening both ecosystems and human livelihoods.



According to UN reports, drought-related economic losses currently exceed $300 billion annually, a figure that is likely to climb as water becomes more scarce.



Beyond financial tolls, the social and humanitarian impacts are staggering - droughts exacerbate <a href="https://www.earth.com/news/late-rainy-season-signals-upcoming-food-insecurity/" target="_blank" rel="noreferrer noopener">food insecurity</a>, force mass migrations, and heighten conflicts over dwindling resources.



<h2 class="wp-block-heading" id="h-the-growing-drought-crisis">The growing drought crisis</h2>



Projections for the future are even grimmer. By 2050, up to three-quarters of the global population could face drought conditions, placing unprecedented pressure on agriculture, water management systems, and urban planning. 



Regions already vulnerable will bear the brunt, but no part of the world will remain untouched. 



Rising temperatures, erratic rainfall patterns, and shrinking freshwater supplies are converging to create a perfect storm of challenges that require immediate and coordinated global action.



If no bold measures are taken, the ripple effects could jeopardize progress toward several UN Sustainable Development Goals, including ending poverty, ensuring food security, and promoting peace and justice. 



Addressing the drought crisis is not merely a matter of environmental stewardship - it is a necessity for global stability and resilience.



<h2 class="wp-block-heading" id="h-african-nations-push-for-stronger-measures">African nations push for stronger measures</h2>



African countries stood united in pushing for a binding agreement. 



One African delegate, speaking anonymously, shared the hope for mandatory drought preparation plans, stating: "It's the first time I've seen Africa so united, with a strong united front, with respect to the drought protocol."



The divide between nations became clear as developed countries preferred a looser "framework" approach rather than binding commitments. 



This position frustrated both African nations and Indigenous groups that were seeking stronger measures.



Praveena Sridhar of Save Soil suggested moving forward despite the lack of agreement.



"The absence of a protocol from COP16 shouldn't delay progress," said Sridhar, noting that governments can still support farmers through sustainable land management programs.



<h2 class="wp-block-heading" id="h-financial-commitments-and-future-plans">Financial commitments and future plans</h2>



The talks weren't without some progress. Various organizations, including the Arab Coordination Group and the Riyadh Global Drought Resilience Partnership, pledged over $12 billion toward <a href="https://www.earth.com/news/toilet-to-tap-california-approves-wastewater-recycling-amid-drought-crisis/" target="_blank" rel="noreferrer noopener">drought resilience efforts</a>.



However, this falls short of the UN's estimated need of $2.6 trillion for land restoration by 2030.



Saudi Environment Minister Abdulrahman AlFadley emphasized his country's commitment, stating they are dedicated "to working with all parties to preserve ecosystems, enhance international cooperation to combat desertification and land degradation, and address drought."



<h2 class="wp-block-heading" id="h-finding-common-ground">Finding common ground</h2>



The discussions revealed an interesting dynamic, as noted by Sridhar. Unlike climate talks that focus on controversial topics like fossil fuels, land preservation discussions offer more common ground.



"Attending to land, agriculture lands, farmers, livestock – it's not a contested subject. Nobody's going to say 'I don't want food.' The use of fossil fuels or not is a very polarizing subject. This is not," said Sridhar.



The next opportunity for progress will come at COP17 in Mongolia in 2026, where nations again hope to finalize a <a href="https://www.earth.com/news/formal-agreement-needed-to-define-the-current-level-of-global-warming/" target="_blank" rel="noreferrer noopener">global drought agreement</a>.

UN talks on the drought crisis end without agreement

In a setback for environmental protection efforts, recent UN talks failed to produce a concrete plan for addressing worldwide drought concerns.

Curbing Short-Lived Pollutants. Ozone, methane and aerosols (tiny pollutant particles) remain in the atmosphere for a shorter time than CO2, but can affect both the climate and air quality. Yet environmental policies tend to separate the two issues, with measures that fight air pollution not always bringing climate benefits and vice-versa. A new study looking into short-lived pollutants reveals measures governments could implement to substantially improve air quality as well as fight climate change. The results, by a team of scientists from around Europe and <a href="http://www.earth.com/image/historic-flooding-has-killed-hundreds-across-china/">China,</a> are published today (24 September) in Atmospheric Chemistry and Physics, an open access journal of the European Geosciences Union (EGU).

In the EU, the reduction in life expectancy due to air pollution was 7.5 months in 2010, and legislation already in place to improve air quality aims to reduce this loss to 5.2 months by 2030. The team says the new measures targeting short-lived pollutants could boost air quality and reduce loss of life expectancy even further: by a month in Europe, about two months in China and one year in India.

The new mitigation measures would also bring climate benefits, reducing global temperatures by about 0.22°C by 2050, relative to a scenario without these measures. The reduced warming in the Arctic would be even larger, close to half a degree, while in Southern Europe the measures would not only reduce temperatures but also increase rainfall by about 15 mm/year, or about 4% of the total precipitation. "This could help to alleviate expected future drought and water shortages in the Mediterranean region," says lead-author Andreas Stohl from the Norwegian Institute of Air Research.

Working within a European project called ECLIPSE, the international consortium of researchers considered short-lived substances that not only affect warming but are also air pollutants, or are transformed into air pollutants once in the atmosphere. Methane, for example, is the second strongest contributor to climate warming after CO2 and is also an ozone precursor: chemical reactions in the atmosphere involving methane produce ozone, a pollutant that presents significant health risks.

"We have found that the measures to reduce methane and other ozone precursors would significantly improve the ozone air quality, especially over northern continents. This would be good for human health and would improve crop yields, confirming the additional benefits of mitigation," says co-author William Collins from the University of Reading, UK. Overall, the new measures would lower global anthropogenic emissions of methane by 50% and of black carbon aerosols, also known as soot, by 80%.

The scientists say the most important measures concern the oil and gas industry. Preventing unintended leaks during the extraction of shale gas would diminish methane emissions, for example. Ending the flaring of gas produced during oil extraction, on the other hand, would lower emissions of black carbon.

"There are also other important measures to reduce methane emissions from coal mining, municipal waste treatment and gas distribution, for example, as well as black carbon emission reductions through elimination of high-emitting vehicles, use of cleaner biomass cooking and heating stoves, replacement of kerosene wick lamps with LED lamps and other measures," adds Zbigniew Klimont of the International Institute for Applied Systems Analysis, Austria, who also took part in the study.

"There is no doubt that the most important factor causing climate warming are CO2 emissions and this must be the prime target of our climate policies. Yet, there is merit in not completely ignoring other climate forcers, which could affect the rate of warming, particularly over the next few decades," says Stohl. "And what is probably even more important: targeting these substances would lead to large improvements in global air quality."

As detailed in the Atmospheric Chemistry and Physics study, the team looked into emission scenarios for various short-lived pollutants and into climate models to find out what the impact of specific emission reductions on climate would be. While methane and black carbon contribute to warming, other aerosols, like those formed from sulphur dioxide (released in volcanic emissions and from coal-fired power plants, for example), have a cooling effect. The team focused on emission reductions that resulted in win-win situations between climate policy and air quality policy.

While the researchers hope to see policymakers implement the ECLIPSE measures, they caution that short-lived pollutants are only a small part of the climate problem. "The project results clearly show that reductions in the emissions of short-lived species cannot replace CO2emission reductions, not even in the short term," warns Stohl.

Measuring Air Quality Data From California Wildfires. On Aug. 19, 2015, a team of scientists from NASA’s Ames Research Center organized the flight of an Alpha Jet to collect environmental data from two recent wildfires in California’s Southern Sierra <a href="http://www.earth.com/news/wildfire-danger-will-continue-to-increase-in-california-and-nevada/">Nevada</a> mountain range.

As part of the ongoing <a href="http://geo.arc.nasa.gov/ajax/ajax_index.html" target="_blank" rel="noopener noreferrer">Alpha Jet Atmospheric eXperiment (AJAX)</a> project, pilots of H211, LLC, a NASA partner, flew through plumes of smoke from the “Cabin Fire” and “Rough Fire” in Sequoia National Forest, California, measuring ozone and greenhouse gases from the fires to understand their effects on air quality. Measuring Air Quality Data From California Wildfires

“It gives us a more complete picture of wildfires,” said Warren Gore, chief of the Atmospheric Science Branch at Ames, based in Moffett Field, California. “It gives information on what is burned and what pollution is produced. Ozone can cause respiratory distress when people breathe it in, whether they have respiratory problems or not. It could affect their health, and it could have a long term effect.”

The California Department of Forestry and Fire Protection (CAL Fire) believes lightning ignited the “Cabin Fire,” which has consumed approximately 7,000 acres in the Golden Trout Wilderness, north of Glendora, since July 19. The “Rough Fire,” which started on July 31, also a result of lightning, has burned more than 100,000 acres in Kings Canyon, near Hume Lake. Twenty-five hundred people from the Hume Lake Christian Camp and surrounding area were evacuated.

“Smoke from wildfires can be lifted high into the atmosphere and transported long distances. It affects not only local air quality but can also have regional and even global impacts”, said Laura Iraci, AJAX Principal Investigator and research scientist at Ames. “For example, the smoke from these fires is impacting large areas of California and Nevada.”

“We’ve seen more methane for every molecule of carbon dioxide emitted from these particular fires than we’ve seen with previous fires,” said Emma Yates, a research scientist at NASA Ames. “We don’t know what’s causing this. Interactions between urban pollution and forest fires is a big challenge, the difficulty being how to identify how much each source contributes to measured concentrations within a mixed wildfire-urban plume. Some researchers speculate that could be playing a role.”

This flight was the 167th AJAX mission in the past five years, using onboard equipment to make measurements of the atmosphere. Results gathered from the 2013 Rim Fire in Stanislaus National Forest are being prepared for publication. Similarly data from this year's fires will be analyzed and shared with the science community and other stakeholders, like the California Air Resources Board and the San Joaquin Valley Air Pollution Control District. Information provided by AJAX can supplement the decision process of these regulatory agencies.

NASA enables studies that unravel the complexities of our planet from the highest reaches of Earth’s atmosphere to its core. NASA’s expertise in space and scientific exploration contributes to essential services provided to the American people by other federal agencies, such as weather forecasting and natural resource management. Scientists worldwide use NASA data to tackle some of the biggest questions about how our planet is changing. Earth science research at Ames features basic and applied research in atmospheric and biospheric sciences, and conducts airborne science campaigns.

90 Percent Of All Scientists Believe In Man-Made Climate Change. A Purdue University-led survey of nearly 700 scientists from non-climate disciplines shows that more than 90 percent believe in man-made climate change -- that average global temperatures are higher than pre-1800s levels and that human activity has significantly contributed to the rise.

The study is the first to show that consensus on human-caused climate change extends beyond climate scientists to the broader scientific community, said Linda Prokopy, a professor of natural resource social science.90 Percent Of All Scientists Believe In Man-Made Climate Change

"Our survey indicates that an overwhelming majority of scientists across disciplines believe in anthropogenic climate change, are highly certain of these beliefs and find climate science to be credible," Prokopy said. "Our results also suggest that scientists who are climate change skeptics are well in the minority."

Previous studies have shown that about 97 percent of actively publishing climate scientists believe in human-caused climate change, and a review of scientific literature on the existence of climate change indicated that about 97 percent of studies affirm climate change is happening.

However, no direct surveys had assessed whether the general agreement on the impact of human activities on the Earth's climate extended to scientists in other disciplines.

Prokopy and fellow researchers conducted a 2014 survey of scientists from more than 10 non-climate disciplines at Big Ten universities to determine the relative prevalence of belief in, and skepticism of, climate change in the scientific community.

Of 698 respondents, about 94 percent said they believe average global temperatures have "generally risen" compared with pre-1800 levels, and 92 percent said they believe "human activity is a significant contributing factor in changing mean global temperatures."

Nearly 79 percent said they "strongly agree" and about 15 percent "moderately agree" that climate science is credible. About 64 percent said climate science is a mature science compared with their own field, and about 63 percent rated climate science as "about equally trustworthy" compared to their discipline.

Disagreement about climate change is rarely a simple dispute about facts, Prokopy said. People's interpretation of information can also be influenced by their cultural and political values, worldview, and personal identity. Prokopy's research team found that division over climate change was linked to disagreement over science - such as the potential effects of carbon dioxide on the Earth's climate - but also differing cultural and political values, which the survey gauged in a section of questions on respondents' general worldviews.

While cultural values did not appear to influence scientists as much as previous studies have shown they influence the general public on a variety of issues, including climate change, the survey indicated that "when it comes to climate change, scientists are people, too," said lead author Stuart Carlton, a former postdoctoral research assistant in Prokopy's lab.

"While our study shows that a large majority of scientists believe in human-caused climate change, it also shows that their beliefs are influenced by the same types of things that influence the beliefs of regular people: cultural values, political ideologies and personal identity," he said.

Prokopy said she was "quite surprised to find cultural values influencing scientists as much as they are. This shows how strong these values are and how hard they are to change."

Respondents' certainty in their beliefs on climate change appeared to be linked to the source of their climate information. Certainty was correlated to how much of respondents' climate information came from scientific literature or mainstream media, Prokopy said. The more respondents relied on scientific studies for information on climate change, the greater their certainty that human activity is causing the Earth's temperatures to rise.

"Climate literature is very compelling and convincing," she said. "Scientists are not fabricating their data."

Nearly 60 percent of those who believe in climate change said they were "extremely sure" and about 31 percent said they were "very sure" average global temperatures have risen. Respondents who said they believe global temperatures have fallen or remained constant were "significantly less certain" in their beliefs, Prokopy said.

Carlton said the tendency of some media to portray climate change as more controversial among scientists than it actually is could decrease people's certainty in whether climate change is occurring and its potential causes.

"The media probably do this for good reasons: They want to give each side of a story to try to be balanced," said Carlton, now the healthy coastal ecosystems and social science specialist at Texas Sea Grant. "However, our study shows that there is very little disagreement among climate scientists or other scientists about the existence of climate change or the quality of climate science as a discipline. There are important questions about what we should do about climate change, but those are policy controversies, not science controversies."

The survey results did not reveal many strikingly different responses by discipline, Prokopy said, though among the fields of study represented, natural resource scientists showed the highest amount of skepticism that global temperatures have risen.

Respondents across disciplines nearly unanimously agreed that climate science is credible, but views on its maturity and trustworthiness compared with their own discipline varied. Physicists and chemists, for example, rated climate science as a highly credible discipline but gave it lower marks in trustworthiness and overall maturity compared with their own fields. Prokopy said this was "not surprising given that physics and chemistry are some of the oldest, most established scientific disciplines."

While previous studies showed that many prominent climate science skeptics were physicists, Carlton said this survey did not show similar evidence.

"The proportion of physicists and chemists who believed in climate change was right around average."

Using Blacklists To Protect The Rainforests. Brazil's public authorities regularly publish "blacklists" of municipalities with high illegal rainforest deforestation rates. This environmental policy tool is working: scientists at the Center for Development <a href="http://www.earth.com/news/biomedical-research-could-protect-humans-from-next-pandemic/">Research</a> (ZEF) and the Institute for Food and Resource Economics (ILR) at the University of Bonn have found that the public shaming strategy reduced Amazon forest loss in the blacklisted districts by 26% per year. Their findings have now been published in the journal PLOS ONE.Using Blacklists To Protect The Rainforests

Deforestation in the Brazilian Amazon has declined recently. While in 2004, trees were still being felled on more than 27,000 square kilometers of land, the area was reduced to fewer than 10,000 square kilometers starting in 2009. "There is a whole range of factors causing this," says Elías Cisneros, Junior Researcher at the Center for Development Research (ZEF) and an employee of the Institute for Food and Resource Economics (ILR) at the University of Bonn. For instance, demand for internationally traded agrarian and forestry products also dropped in response to the financial crisis in 2008. However, Brazil's environmental policy has played a key role in protecting the rainforest, as Cisneros has shown in his work with Sophie Lian Zhou (ILR) and Junior Professor Dr. Jan Börner (ZEF).

Public disclosure of districts with high deforestation rates

The researchers studied the effect of so-called blacklists - Brazilian authorities regularly publish the names of communities with the highest deforestation rates. "The media and non-governmental organizations can then increase pressure to hold responsible local actors accountable," reports Börner. According to the researchers' calculations, the "naming and shaming" policy has resulted in an approximately 26 percent drop in deforestation in recent years.

Brazil has used this political tool since 2008. Of the 771 districts in the Brazilian rainforest, "naming and shaming" was introduced in 50 areas with particularly high levels of deforestation. "Blacklisted municipalities may have been worried about economic penalties, among other things," says Cisneros. This fear of losing market opportunities apparently helped to significantly reduce illegal deforestation.

How much deforestation would be taking place without the blacklists?

Stricter controls by authorities are another important factor. Controls are facilitated by Brazil's modern satellite monitoring system. That makes it easier for inspectors to track down offenders of environmental laws on site. "However, our calculations showed that the blacklists are an important influencing factor in addition to the controls," reports Cisneros. The researchers compared the listed communities with comparable non-listed communities. "Between 2008 and 2012, many blacklisted districts have apparently witnessed a collective effort to safeguard their reputation. This effort seems to have been an important driver in protecting more than 4,000 square kilometers, about 40 times the area of the Black Forest National Park in Germany," says Börner in his summary of the findings.Brazil's public authorities regularly publish "blacklists" of municipalities with high illegal rainforest deforestation rates.

The study is based on a term paper by Sophie Lian Zhou, a doctoral student at the Agricultural Science Department of the University of Bonn. She discovered the blacklisting policy in Börner's master-level course on impact evaluation methods and started studying the policy in her final paper. "Börner and Cisneros were interested in the topic, so we pursued it further as a joint research project," says Zhou. The result is a successful example of research-based teaching.

California Regulators To Restore Unique Climate Change Program. California regulators are poised to restore a first-in-the-nation climate change program that requires a 10 percent cut in carbon emissions on transportation fuels sold in the state by 2020, despite <a href="http://www.earth.com/news/life-in-deep-ocean-sediments-can-survive-boiling-hot-temperatures/">oil</a> industry objections that it could drive up gas prices.
After the program survived a lengthy legal challenge from fuel makers, regulators are expected to vote Friday on the clean <a href="https://www.bing.com/search?q=fuel&amp;cvid=73d3c3dfaa6a41e78afa7996c05e2786&amp;FORM=ANAB01&amp;PC=HCTS">fuel</a> standard, which environmentalists and some business groups are hailing as one of California's most important moves to reduce greenhouse gas emissions. California Regulators To Restore Unique Climate Change Program
The California Air Resources Board estimates the economic impact to consumers would be a few cents per gallon, costing a typical commuter $5 to $21 extra in 2017, increasing to $12 to $48 annually in 2020.California Regulators To Restore Unique Climate Change Program
"It is giving clear direction to the fuel-producing sector that this is the direction of the state," said John Boesel, president and chief executive of CALSTART, a transportation business group that supports clean-energy technology.
The standard's expected passage was a boost for Gov. Jerry Brown, who has vowed to intensify his fight against climate change after the oil lobby helped kill a Democratic legislative proposal earlier this month to slash statewide petroleum use by half in 15 years.
Unlike other rules the state has adopted requiring cleaner-burning fuel or more fuel-efficient vehicles, the standard, first proposed in a 2007 executive order from then-Gov. Arnold Schwarzenegger, calls for counting all the pollution required to deliver gasoline, diesel or alternative fuels to in-state consumers - from drilling a new oil well or planting corn to delivering it to gas stations.
In addition to tailpipe emissions, it includes factors such as whether an ethanol factory uses coal or natural gas to power production or an oil rig uses diesel fuel to drill.
Oil producers say the standard will cost consumers much more in a state with some of the highest gas prices in the nation as the companies try to comply with the mandate or face being shut out of the market.
Supporters say that industry can afford to make it work. They believe the program will encourage greater use of cleaner biofuels and electric vehicles, which can be cheaper to operate than those powered by gasoline or diesel.
The Western States Petroleum Association, which represents oil companies, said there are not enough quantities of low-carbon biofuels to allow refiners to comply with the regulations.
All fuels are measured against a baseline pollution standard. If a fuel falls above or below the baseline, it generates a credit or deficit that other producers can buy and sell to meet the target. It's up to fuel producers to figure out how to meet the goal, whether by changing production methods, using ethanol or electric vehicles for transportation or buying credits on the market.
Regulators are targeting transportation fuels because California's roughly 30 million vehicles account for about 40 percent of the state's emissions. The rest comes from generating electricity and industrial manufacturing, as well as commercial, residential and agricultural uses.
After the rule's initial adoption, out-of-state refiners and ethanol companies were among those who sued, arguing that transporting the fuels into California alone made them less competitive against in-state producers. They argued the law unconstitutionally limits interstate commerce.
The U.S. Supreme Court let stand a 2013 appeals court decision upholding the fuel standard. Opponents continue to challenge the state's authority to regulate out-of-state production. Oil companies are also trying to block a similar standard enacted in Oregon, the only other state with a clean fuel standard.
Responding to concerns, California's air regulators have proposed changes, including capping the price of credits to avoid price spikes. The board could also add provisions giving credit to refineries for using renewable hydrogen and making other investments to reduce pollutants.
While the reduction target has been frozen at 1 percent, state officials say the industry has met 2 percent of the goal as of last year.

EPA To Change Diesel Emissions Tests After Volkswagen Scandal. The U.S. Environmental Protection Agency plans sweeping changes to the way it tests for diesel emissions after getting duped by clandestine software in <a href="https://www.bing.com/search?q=Volkswagen&amp;cvid=d11ae925f23340058125bfae31e152a7&amp;FORM=ANAB01&amp;PC=HCTS">Volkswagen</a> cars for seven years.
Chris Grundler, head of the EPA's office of transportation and air quality, indicated the agency would add on-road testing to its regimen. VW's sophisticated software allowed its cars to pass tests in the lab and then spew pollution into the <a href="http://www.earth.com/news/earths-atmosphere-beyond-moon/">atmosphere</a> while on the highway.
The revelations meant unwanted scrutiny for the EPA. Its testing procedures have been criticized for being predictable and outdated, making it relatively easy for VW to cheat. What's more, the EPA did not initially uncover the problem; researchers at West Virginia University did, using on-road testing.
Grundler says the changes are designed to detect software and other methods automakers might use to rig a test.
The EPA and the California Air Resources Board have engineers who are "developing clever ways in which these things can be detected," Grundler says.
He also notes that testing of diesel engines, which make up only 1 percent of the vehicles on U.S. roads, wasn't the top priority for the EPA. The agency did have on-road testing equipment - but it was assigned to monitor automaker gas mileage estimates and heavy-duty diesel trucks, where cheating had been uncovered in the past.
Grundler, who has been with the EPA for more than three decades, says the lack of on-road testing for diesels "might change in the future." An announcement of the changes could come on Friday.
VW has admitted to installing software on Volkswagen and Audi cars with four-cylinder diesel engines that switches on pollution controls when they are being tested. When the software, called a "defeat device," determines that the cars are back on real roads, the controls are turned off. The EPA says about 500,000 U.S. cars including the Jetta, Golf, Beetle, Passat and Audi A3 have the cheating software, and VW says a total of 11 million cars have it worldwide.
VW was able to fool the EPA because the agency only tested the cars on treadmill-like devices called dynamometers and didn't use portable test equipment on real roads. The software in the cars' engine-control computers checked the speed, steering wheel position, air pressure and other factors to determine when dynamometer tests were under way. It then turned on pollution controls that reduced the output of nitrogen oxide, an ingredient in harmful ozone, the EPA has said.
VW started the scheme with the 2009 model year, and may not have been caught without testing performed at West Virginia University on behalf of the International Council on Clean Transportation, a nonprofit group that advises governments on regulations. EPA and California regulators confronted VW with those findings to VW in May 2014. The automaker eventually did a recall late last year, without much improvement, the EPA says.
Only when the EPA and CARB refused to approve VW's 2016 diesel models for sale did the company admit what it had done.
The EPA announced the violations a week ago and said VW could face billions in fines. The agency said the cars are safe to drive but VW will have to pay to recall and fix them. The agency also is going to test diesels from other manufacturers to make sure they don't have similar devices.
Sen. Bill Nelson of Florida is frustrated that regulatory agencies such as the EPA are failing to protect the public. "Seven years is way too long a time that the EPA has been asleep at the switch," he says.
He says the VW case has similarities to those involving General Motors ' defective ignition switches and Takata Corp.'s exploding air bag inflators, where it also took years before those problems were disclosed to consumers.
"When there is this kind of deception, we've got to get these agencies to be able to cut through it and catch it," Nelson says.The U.S. Environmental Protection Agency plans sweeping changes to the way it tests for diesel emissions after getting duped by clandestine software in Volkswagen cars for seven years.
It's not the first time the EPA has had to change testing to make sure automakers are playing by the rules. Earlier this year the agency updated gas mileage tests after some automakers were caught with inflated window sticker estimates.
Grundler disputes the notion that EPA would never have caught VW without the outside help. European regulators were looking into VW's on-road diesel emissions as far back as 2012, and since diesels make up half the cars there, the EPA decided to let Europe take the lead, he says.
"I don't think it's fair to say that this would never have been uncovered," he says. "Do I wish we had uncovered it sooner? Absolutely."

INDIA FESTIVAL

India: Poverty Is Key Source Of Global Pollution. India will confirm plans next week for a fivefold increase in renewable energy by 2020, the environment minister said. But it will continue to champion poor countries in their demand that industrialized nations assume the brunt of responsibility for decades of climate-warming emissions.
Describing poverty as a key source of <a href="http://www.earth.com/news/planting-trees-could-slow-global-warming-but-it-wont-be-cheap/">global</a> pollution, Prakash Javadekar told The Associated Press on Thursday that nations hoping to reach a global climate pact in Paris in December must commit to a world where all 7 billion-plus inhabitants have equal rights and access to electricity, opportunity and justice. India: Poverty Is Key Source Of Global Pollution
"Poverty is, in a way, a real polluting factor," Javadekar said, adding that India's top priority is elevating hundreds of millions of Indians still living on less than $2 a day. At the same time, expanding the economy and building infrastructure will cause carbon emissions to grow, as the country relies on burning coal to fuel most of the 254 GW of electricity it generates today.
"But today, I see the carbon space occupied by the developed world," he said. "We are asking the developed world to vacate the carbon space to accommodate us. That carbon space demand is climate justice. It's our right as a nation. It's our right as people of India, and we want that carbon space."
India is one of the last major polluters yet to submit its plans for combating and coping with climate change to the United Nations, before the world's nations attempt to nail down a global climate pact in December. As Prime Minister Narendra Modi joins other world leaders at the U.N. General Assembly meeting Friday, experts and officials are eager for India's climate commitments.
Already, countries and territories accounting for at least 60 percent of global emissions have announced their targets, including the world's No. 1 and 2 polluters, China and the <a href="https://www.bing.com/search?q=United+States.&amp;cvid=4d2471a71de6483bba2bc696a34d5de3&amp;FORM=ANAB01&amp;PC=HCTS">United States.</a> But experts say the pledges so far fall short of what's needed keep temperatures from rising more than 2 degrees Celsius by mid-century - a level beyond which scientists say we'd see extreme climate changes, including sizzling hot summers, much higher sea levels, torrential storms and more severe droughts. Current national pledges put us on track for a 2.9 to 3.1 degree temperature rise.
On Thursday, Indonesia submitted its pledge to the U.N., vowing to strengthen forest protection and increase renewable energy production to account for at least 23 percent of the Southeast Asian island nation's total capacity by 2025.
Experts have worried that India's position could doom global efforts to limit the rise in temperatures.
"India for a long time has been resistant to the notion of developing countries taking targets at all," former U.N. climate chief Yvo de Boer said Thursday in Paris. "Modi has indicated he wants to make a very big push on the economy, focus more on manufacturing. There's a lot of coal in India so the logical fuel for him to choose in driving that growth is coal. If he takes an ambitious climate target, that means he wants to balance that growth with climate ambitions."
Javadekar said the Indian pledge on climate action will be released Oct. 1, and will include targets not only for increasing renewable energy but also for curbing its emissions intensity, or how much carbon dioxide the country produces divided by its GDP. In 2009, India said it could cut emissions intensity by 20 to 25 percent below 2005 levels by 2020. Javadekar indicated the new intensity target would be more ambitious, but he would not give details.
The pledge will not include targets for cutting overall emissions, and it will not include a projection for when India's emissions growth might peak.
"Nobody has actually asked us for this ... because they know India's particular situation," the minister said, alluding to India's relatively low emissions rate of 1.6 tons per capita compared with a U.S. rate that is about 10 times higher. While the U.S. and China, emitting around 7 tons per capita, pledged to bring theirs to a common 12 tons per capita by 2030, India "will never reach there," Javadekar said. "I don't see going beyond 10 any time soon."
India's plans for a fivefold boost in renewable energy, from about 34 GW today to 175 GW by 2020, had been promised earlier by Modi as he vowed to bring universal electricity access to India's 1.2 billion people by 2020. The 175 GW goal includes 100 GW of new solar power, 60 GW from wind, 10 GW from biomass and 5 GW from small hydropower dams.
It's an astonishing pledge, considering where India is today. A quarter of the country, or 300 million people, still has no access to electricity, while hundreds of millions more make do with just a few hours a day. Blackouts are so common that hospitals and many businesses are forced to use diesel generators, while about a quarter of the 254 GW being produced today is lost in grid leakages and theft.
Experts estimate it will cost at least $150 billion for India to sort out its electricity woes and meet the renewable energy target - funding India does not have. Instead, it will rely on building business opportunities, and will hope for international commitments in waiving high intellectual property costs for technologies that can help India improve its energy production and efficiency.
"We definitely will expect a good amount of technology, affordable technology," Javadekar said. "Why people should profit from disaster? They should actually help India to build this huge program, making it a reality."

China Plans To Launch A Cap-And-Trade System To Reduce Pollution. China is preparing to announce plans to launch a national cap-and-trade system to limit greenhouse gases and force industries to purchase pollution credits,<a href="http://www.earth.com/news/epa-plan-mercury-emissions/"> Obama</a> administration officials said Thursday.
Beijing plans to put the system known as cap-and-trade into place in 2017 as part of measures aimed to address climate change in cooperation with the U.S. and others.
A joint statement to be released following Friday's summit between President Barack Obama and his <a href="https://www.bing.com/search?q=chinese&amp;cvid=7b8db410f3e24ed19f477219230c1f61&amp;FORM=ANAB01&amp;PC=HCTS">Chinese</a> counterpart Xi Jinping aims to flesh out how their two countries plan to achieve targets for cutting emissions set at a bilateral summit in Beijing last year.China Plans To Launch A Cap-And-Trade System To Reduce Pollution
The officials, who spoke on condition of anonymity so they wouldn't pre-empt China's official announcement, said it's hoped the announcement will give impetus to a broader global treaty on climate change at a Paris conference in December.
The announcement will also cover components of the cap-and-trade strategy, including the individual sectors covered under the plan, which range from power production to papermaking, the officials said. Those sectors produce "a substantial percentage of China's climate pollution," one official said.
Cap-and-trade sets an annual limit on the amount of pollution that can be produced, then requires firms to obtain permission to pollute by purchasing credits from less polluting industries.
Other parts of China's announcement will include prioritizing low-carbon and efficient electricity production.
Under last year's groundbreaking agreement, Obama set a goal to cut U.S. emissions between 26 percent and 28 percent by 2025, compared with 2005 levels.
China, the world's biggest polluter, relies heavily on coal for power generation. It will set a target for its emissions to peak by about 2030 or earlier, after which they would then start falling. That marks an unprecedented step for Beijing, which has been reluctant to be boxed in on climate by the global community.
The European Union has also said it would cut its emissions 40 percent by 2030, compared with 1990 levels. Taken together, the U.S, China and the EU account for more than half of global emissions.
Friday's announcement will also commit Beijing and Washington to aligning their views on key negotiating positions at Paris, along with providing greater funding for research and development on low-carbon technologies and financial assistance to help poor countries build low-pollution infrastructure.
China, one of the world's biggest builders of infrastructure, will also offer a "very substantial financial commitment" to help poor nations transition to low-pollution technologies, the U.S. officials said, without releasing the exact figure.
Three decades of breakneck economic growth have left China's cities clogged in dense smog and sent cancer rates soaring. That's prompted it to drop its insistence that developed nations bear most of the responsibility for reducing carbon emissions, producing a rare area of cooperation with Washington.
Lu Kong, the spokesman for Xi's delegation, declined to discuss the joint statement, but said climate change was "an area where China and the U.S. could work together and we did make some good progress in our joint efforts.
"Maybe this time we could make further progress in demonstrating to the outside world at large that China and the U.S. are committed to further efforts in dealing with climate change in a comprehensive way," Lu said.

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.

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;

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.

Today's Video of the Day from the <a href="http://www.esa.int/">European Space Agency</a> features Qeshm Island in the Strait of Hormuz. This strait provides the only sea passage from the Persian Gulf to the open ocean.



Qeshm is separated from the Iranian coast by the Clarence Strait, also known as Khuran.&nbsp;The Hara Forest Protected Area is a network of shallow waterways and forest located between the island and the mainland. This protected region is home to sea turtles, snakes, and more than 150 species of migrating birds.



Qeshm is famous for its wide range of&nbsp;ecotourist&nbsp;attractions, such as the&nbsp;Hara marine forests. According to environmentalists, about 1.5 percent of the world birds and 25 percent of Iran's native <a href="https://www.earth.com/news/female-hummingbirds-avoid-sexual-harassment-by-looking-like-males/">birds</a> annually migrate to the forests, which are the first national geo park in Iran.



Tourists are also drawn to the island to see an age-old Portuguese&nbsp;fort, historic mosques, the&nbsp;Seyyed Mozaffar&nbsp;and&nbsp;Bibi Maryam&nbsp;shrines, and the "Valley of Stars."



The average temperature on the island is 81 degress and the region is often hot and humid. From June to August, the island is described as being oppressively hot. The ideal time to visit is during the winter season.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Inhambane Bay in southeast Mozambique.&nbsp;



"Inhambane Bay is a deep inlet into which the small Mutamba River flows," says ESA. "On one side of the bay lies the historical city of Inhambane, capital of the Inhambane Province, while the sister city of Maxixe, the economic capital of Inhambane, sits across from it. The province is the second largest grower of cashews, after Nampula, and it also produces coconut and citrus fruits."



The beaches of Barra and Tofo are popular with tourists. There are also coral reefs along the long coastline of Inhambane, making it an ideal destination for scuba diving and snorkeling.



"Mozambique’s extensive coastline heightens the country’s vulnerability to tropical cyclones that develop in the Indian Ocean as well as storm surge flooding," says ESA.



"More than half of the population lives in low lying coastal areas, putting communities at risk. Inhambane Bay was dangerously close to where Cyclone Idai made landfall in 2019 causing widespread destruction to the country."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency </a>&nbsp;features the Kangerlussuaq Glacier, one of the largest tidewater outlet glaciers in Greenland. The glacier is located on the east coast of the Greenland ice sheet.



As human-induced climate change continues to drive up temperatures, global ice loss is accelerating at an alarming rate. ESA reports that, over the past decade alone, 3.5 trillion tons of ice have melted from the Greenland ice sheet. This is enough to cover the UK with meltwater 15 meters deep.



Based on satellite imagery, researchers determined that Kangerlussuaq entered a new phase of rapid retreat and acceleration in 2017. In their study, published in <a href="https://www.frontiersin.org/articles/10.3389/feart.2019.00123/full">Frontiers in Earth Science</a>,&nbsp; the experts report that the glacier's ice front is now at its most retreated position since the early 20th century.



"Given Kangerlussuaq’s previous impacts on both the magnitude and pattern of ice sheet wide mass loss, we predict that its new phase of retreat, acceleration and thinning will markedly enhance the south-east region’s contribution to increasing discharge from the ice sheet," wrote the study authors.&nbsp;&nbsp;



"More broadly, accurate forecasting of the ice sheet’s contribution to sea level rise will require a deeper understanding of, and responses to, these non-linear ice dynamic processes."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the complex relationship between ocean and climate. ESA's Climate Change Initiative will help us understand how oceans influence the climate and how climate change is impacting the oceans.&nbsp;



"Earth’s oceans are huge heat stores, soaking up 93% of the excess heat from human activity over the past 70 years. Ocean currents redistribute heat around the planet, from the Equator to the poles. Where this ocean heat goes influences weather patterns and regional climate," explains ESA.



"As well as absorbing heat, oceans are a natural carbon sink, absorbing a quarter of carbon dioxide emissions from human activity. This has led to the acidification of ocean water, threating marine life."



The amount of heat and carbon dioxide soaked up by the ocean depends on specific variables, including phytoplankton, temperatures, waves, salinity, and ice cover. Satellites can be used to measure these variables from space.



"From their unique vantage point, satellites provide key information for understanding the complexities of our planet and monitoring environmental issues," says ESA.

"A project supported by the Discovery element of ESA’s Basic Activities recently investigated a new technique to measure sea surface topography very precisely," reports ESA.



"The technique involves looking at satellite navigation (GNSS) signals that have been reflected off of the sea surface at very low angles. At these so-called grazing angles, waves and surface roughness have very little impact on the reflection process; the sea surface acts as a very smooth mirror."



Estel Cardellach is the principal investigator at the Institute for Space Studies of Catalonia, who first submitted the idea for the project.



“In a mirror-like reflection the phase of the signal can be tracked – it is continuous," said Cardellach. "Different surface heights result in different phase measurements. It gives a very precise measurement of the surface altitude at a few centimetres’ precision.”



The researchers developed a GNSS receiver and set up an experiment in the Balaeric Islands to collect signals from the receiver that were reflected off the sea surface. Ultimately, these signals will provide improved measurements of the shape of the sea surface.

Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA’s Goddard Space Flight Center</a> describes how scientists are using autonomous sound sensors to monitor deforestation in the Amazon. By recording soundscapes, the experts can determine which animals are present through their distinct sounds.&nbsp;



Using this method, sounds can be used as scientific measurements to analyze the effects of deforestation. The researchers will gain a better understanding of how the acoustics of a forest can be used to measure its health.&nbsp;



"From space, parts of the Amazon rainforest that have previously been logged or burned may look lush and green, like a place buzzing with activity and full of sounds. But inside the rainforest, the animal life may tell a different story, of a harsh environment and a quieter soundscape," says NASA.
