On World Ozone Day, we celebrate global efforts to protect and restore the ozone layer, a vital shield that protects life on Earth from harmful ultraviolet (UV) radiation.&nbsp;



World Ozone Day was established by the United Nations General Assembly in 1994. This occasion highlights the <a href="https://www.earth.com/news/decline-in-ozone-depleting-chemicals-is-an-encouraging-trend/" target="_blank" rel="noreferrer noopener">success</a> of the Montreal Protocol, an international treaty adopted in 1987, which has been instrumental in phasing out the production and use of ozone-depleting substances.&nbsp;



<h2 class="wp-block-heading" id="h-climate-action-on-world-ozone-day-nbsp">Climate action on World Ozone Day&nbsp;</h2>



World Ozone Day is an important reminder of the link between <a href="https://www.earth.com/news/wildfires-threaten-the-recovery-of-the-ozone-layer/" target="_blank" rel="noreferrer noopener">ozone protection</a> and climate action. The phasing out of ozone-depleting chemicals has greatly contributed to reducing greenhouse gas emissions and slowing global warming.



<div class="wp-block-sendtonews-playerselector">[sendtonews key="iO1Qd1FFM1-3858489-12187" type="single"]</div>



“The theme for this year's World Ozone Day (WOD) is Montreal Protocol: Advancing Climate Action. This theme underscores the critical role the Montreal Protocol plays in not only restoring the stratospheric ozone layer but also in mitigating climate change,” noted James Curlin, head of the <a href="https://www.unep.org/node" target="_blank" rel="noreferrer noopener">UNEP</a> Law Division’s OzonAction Branch.



“It serves as a powerful reminder of our collective responsibility to continue and intensify our efforts to fight climate change through any means possible, be it through the phase out of hydrochlorofluorocarbons (HCFCs) and other ozone depleting substances, or through the phase down of hydrofluorocarbons (HFCs).”&nbsp;



“By doing so, we can significantly reduce both the direct and indirect emissions of gases that heat our planet, contribute to the broader goals of climate action, and build a sustainable future for all.”



<h2 class="wp-block-heading" id="h-what-is-ozone-depletion">What is ozone depletion?</h2>



<a href="https://www.earth.com/news/burning-up-of-satellites-severely-harms-ozone-recovery/" target="_blank" rel="noreferrer noopener">Ozone depletion</a> refers to the gradual thinning of the Earth’s ozone layer in the stratosphere. This phenomenon is primarily caused by the release of ozone-depleting chemicals containing gaseous chlorine or bromine from industrial and consumer products.&nbsp;



<h3 class="wp-block-heading" id="h-contributing-factors">Contributing factors</h3>



The most significant contributors are chlorofluorocarbons (CFCs), halons, and other related <a href="https://www.earth.com/news/monsoons-launch-ozone-depleting-substances-into-the-stratosphere/" target="_blank" rel="noreferrer noopener">substances</a>.&nbsp;



When these chemicals are released into the atmosphere, they eventually reach the stratosphere, where ultraviolet (UV) radiation breaks them down, releasing chlorine and bromine atoms.&nbsp;



These atoms then react with ozone (O3) molecules, causing the ozone to break apart into oxygen molecules (O2) and single oxygen atoms, thus depleting the ozone layer.



<h3 class="wp-block-heading" id="h-impacts-of-ozone-depletion">Impacts of ozone depletion</h3>



The depletion of the ozone layer has significant environmental and health impacts.&nbsp;



A thinner ozone layer allows more harmful UV-B radiation to reach the Earth’s surface, which can lead to an increase in skin cancers, cataracts, and other health issues.&nbsp;



Ozone depletion also affects ecosystems, particularly marine life, as increased <a href="https://www.earth.com/news/antarctic-ozone-hole-exposes-wildlife-to-harmful-uv-radiation/" target="_blank" rel="noreferrer noopener">UV radiation</a> can harm phytoplankton, the base of the marine food web.



<h2 class="wp-block-heading" id="h-success-of-the-montreal-protocol-nbsp">Success of the Montreal Protocol&nbsp;</h2>



As we celebrate the success of the Montreal Protocol, we must recognize the need to address ongoing environmental threats.&nbsp;



Hydrofluorocarbons (HFCs) are chemicals that were introduced as replacements for ozone-depleting substances like chlorofluorocarbons (CFCs).



However, despite their ozone-friendly nature, HFCs have a global warming potential (GWP) that can be hundreds to thousands of times greater than carbon dioxide.&nbsp;



Recognizing this issue, the Kigali Amendment to the Montreal Protocol, adopted in 2016, was created to phase down the production and use of HFCs. This amendment aims to reduce the use of HFCs and minimize their impact on global warming, while maintaining the protection of the ozone layer.



<h2 class="wp-block-heading" id="h-international-cooperation-on-world-ozone-day-nbsp">International cooperation on World Ozone Day&nbsp;</h2>



World Ozone Day is also a celebration of international cooperation, as nations across the globe have united to tackle a major environmental threat.&nbsp;



The progress in healing the ozone layer shows how collective action can address global challenges.&nbsp;



“At a time when multilateralism is under severe strain, the Montreal Protocol to help protect the ozone layer stands out as a powerful symbol of hope.&nbsp; It is a reminder that when countries show political resolve for the common good, change is possible,” said UN Secretary-General António Guterres.



“In uniting the world to phase out the consumption and production of different ozone depleting substances, the Protocol has also contributed to shielding carbon sinks, protecting humanity’s health and avoiding economic losses.”



“On this World Ozone Day, let’s commit to making peace with our planet. Let’s commit to build on the success of the Montreal Protocol to show what international cooperation at its best can achieve.”

World Ozone Day 2024: Advancing climate action

On World Ozone Day, we celebrate global efforts to protect and restore the ozone layer, a vital shield that protects life on Earth from harmful ultraviolet (UV) radiation.&nbsp; World Ozone Day was established by the United Nations General Assembly in 1994. This occasion highlights the success of the Montreal Protocol, an international treaty adopted in 1987, which has been instrumental in phasing out the production and use of ozone-depleting substances.&nbsp; Climate action on World Ozone Day&nbsp; World Ozone Day is an important reminder of the link between...

It’s Christmas time – and Hanukkah, too. The festivities include time with family, delicious treats, and brightly wrapped gifts. 

The paper on those brightly wrapped gifts offers a pretty picture, and the act of tearing into a present, not sure what’s inside, all the more fun for young and old.

But what does all that paper mean for the environment?

In the United States alone, 25 percent more trash is thrown away during the period from Thanksgiving to New Year’s Day than the rest of the year combined, according to the <a href="https://www3.epa.gov/region9/waste/recycling/index.html">Environmental Protection Agency</a>. 

Much of that garbage begins its life as festive gift wrap. Each year, four million tons of trees are turned into gift wrap and holiday-themed shopping bags, only to be dropped into landfills, the <a href="http://cleanair.org/">Clean Air Council</a> said.

“Wrapping paper stays on presents for an average of five days. The presents are opened and tons of paper, ribbons and boxes are thrown away,” said Genevieve Adamski in <a href="http://thepointeruwsp.com/2016/12/13/trimming-the-holiday-wasteline/">The Pointer</a>, the student-run newspaper of the University of Wisconsin, Stevens Point.

Sometimes the gift wrap doesn’t even make it to the gift recipient. Almost half of Americans said they would rewrap a gift if it didn’t look the way they wanted, according to information gathered by the website <a href="https://www.creditdonkey.com/gift-wrap.html">CreditDonkey</a>.

It’s not just the U.S., either.

In the United Kingdom, the gift wrap thrown away each year could be laid end to end and wrap the equator nine times, said Lucy Siegle in <a href="https://www.theguardian.com/environment/2010/dec/19/not-easy-being-green-wrapping-paper">The Observer</a>.

The city of Barrie, Ontario in Canada reports that the average Canadian family’s waste increases up to 45 percent during the holidays, much of it wrapping paper from brightly wrapped gifts and supplies needed to create those beautiful, brightly wrapped gifts.

Don’t let statistics put the bah humbug in your holiday spirit, though. Like most industries, some paper is better than others. Taking a few steps can make your Christmas a little greener, to go with merry and bright.

Many types of holiday wrapping and greeting cards can be recycled. However, metallic, glittered and laminated paper can’t be recycled in many locations. Unless you plan to reuse them, those types of gift wraps are probably on the “avoid” list.

Some gift wraps that are heavily dyed are also difficult to recycle, so look for wrapping that is decorative without being overdone.

“If you don't go wrap-free, buy unbleached paper, as high quality and free of glitter penguins as you can. Encourage careful opening and reuse,” Siegle said. 

Gift bags are a good option because they’re often reused several times, she added. 

Some gift wraps contain seeds. While those are a great gift for anyone who loves flowers, make sure they know that the paper belongs in their yard or garden, not the garbage.

If you have the time and inclination, you can use stamps, stencils, and paint to turn brown paper grocery bags into unique, recycled, and recyclable gift wrap.

Whatever you do, don’t burn the wrapping paper you can’t recycle or reuse. 

“Decorative wrapping paper ... can contain lead, synthetic inks, plastic film, chlorine or metal-based foils, which release toxic and carcinogenic compounds into the air when burned,” Eviana Hartman wrote in the <a href="http://www.washingtonpost.com/wp-dyn/content/article/2008/11/20/AR2008112003358.html">Washington Post</a>.

Leftover wrapping paper, holiday cards, and other paper products can be turned into do-it-yourself projects instead, from lining drawers, boxes, and bookshelves to wrapping textbooks to origami paper to creating decor for next year’s Christmas season. 

The EPA also suggests saving ribbons and bows to be reused instead of throwing them away.

A few other ways to cut down on waste this holiday season:
<ul>
 	<li style="font-weight: 400;">Bring your own bags when holiday shopping, or put smaller purchases into bags with larger items instead of requesting a new bag.</li>
 	<li style="font-weight: 400;">Purchase rechargeable batteries and chargers to go with any battery-operated toys or games.</li>
 	<li style="font-weight: 400;">Be sure to recycle the batteries in any greeting cards that play music.</li>
 	<li style="font-weight: 400;">Recycle the cards, too. Card fronts decorated with glitter or foil can be cut off and used in art projects, or donated to preschools or elementary schools for next year.</li>
 	<li style="font-weight: 400;">Choose “experiences” as gifts for people who will appreciate them – concert or sports tickets, museum or zoo memberships, spa gift cards, or day trips.</li>
 	<li style="font-weight: 400;">Buy a living Christmas tree that can be planted when the season is over. If you buy a cut tree, be sure to recycle it. </li>
</ul>

Brightly wrapped gifts aren't always environmentally friendly

It’s Christmas time – and Hanukkah, too. The festivities include...

Methane levels in Earth’s atmosphere have risen drastically in the past two years, causing concern amongst climate change experts. 

While carbon dioxide (CO2) emissions typically get the bulk of the attention, methane (CH4) is actually a more potent greenhouse gas. Over the course of a century, methane is 30 times better than carbon dioxide at trapping heat in the atmosphere. 

Scientists warn the progress made in reducing CO2 emissions could be negated by rising methane levels. 

"CO2 is still the dominant target for mitigation, for good reason. But we run the risk if we lose sight of methane of offsetting the gains we might make in bringing down levels of carbon dioxide,” Professor Robert Jackson of <a href="https://www.stanford.edu/">Stanford University</a> said.

Jackson recently wrote an editorial in the journal <a href="http://iopscience.iop.org/journal/1748-9326">Environmental Research Letters</a> urging the scientific community to act on the lack of knowledge regarding methane. Even experts in the field remain unsure of the exact cause of the recent spike in CH4 levels. 

Methane concentration in the atmosphere remained fairly level from 2000 to 2006, began to uptick in 2007, and then jumped by 10 or more parts per billion in 2014 and 2015. 


Agriculture appears to be one clear cause, as the biological functions of cattle release large amounts of methane into the air. But naturally occurring chemical reactions that remove methane from the air play a significant role in the balancing act and require further study.

Jackson is hopeful that the scientific community can soon make great strides in that area, in large part due to new satellites that can target specific carbon and methane molecules in the air. 


"I'm optimistic that the scientific community and the policymakers will be able to have better information,” Jackson said. “I'm optimistic because there are new satellites coming along that will give us the power to see methane concentrations all over the world on a regular basis. Methane is more difficult to study than CO2 because it's more diffuse, but I think we’re poised to make really good progress over the next few years."

According to a new study by <a href="http://www.rice.edu/">Rice University</a>, American evangelicals are more likely to believe in climate change than evolution. The study found that 20 percent of those surveyed said that they were skeptical that climate change is occurring or that humans have any role in climate change. But 45 percent of those surveyed said that natural evolution is probably or definitely a false concept.

The study also found that religion is more closely tied to evolution skepticism than it is to climate change skepticism. Around 70 percent of those who identify as evangelicals said that evolution is most likely false, but only 28 percent of that population said that climate change is not occurring or that humans have no role in climate change. 

The study, titled "Examining Links Between Religion, Evolution Views and Climate-Change Skepticism,” was published in the latest edition of <a href="http://eab.sagepub.com/">Environment and Behavior</a>. It focused on the larger “anti-science” mentality as it relates to membership in conservative religious groups.

A team of researchers, led by Rice sociologist Elaine Howard Ecklund, studied the link between evolution skepticism and climate-change skepticism with regard to religious affiliation. The team surveyed 9,636 people in the U.S. population which, according to Ecklund, is up to 40 percent evangelical, depending on how “evangelical” is defined.

Said Ecklund, "This is different from the popular account that the people who oppose climate change research and the people who oppose the teaching of evolution are the same, and that evangelical Protestantism is clearly linked to both.”

Climate scientists are looking beyond preventing greenhouse gas emissions. Now, they’re looking at a potential method of turning global warming into global cooling: aerosol “antacids.”

Instead of looking for yet another idea to prevent climate change, a team of researchers from <a href="http://www.harvard.edu/">Harvard University</a> had a cool idea. They would study the atmospheric conditions that cause cooling after a volcanic eruption, and seek a way to reproduce it.

Most massive volcanic eruptions shoot tons of sulphur dioxide into the air. That causes a cooling effect that can be felt regionally or even globally. 

For example, the “Year Without a Summer” – actually a three-year period – was linked to the April 1815 eruption of Mount Tambora in Indonesia. In the midst of the “Little Ice Age,” the eruption dropped temperatures up to 1.3 degrees Fahrenheit in the Northern Hemisphere.

Cooler global temperatures were recording for three to four years following the 1883 eruption of Mount Krakatoa in Indonesia, and the 1991 eruption of Mount Pinatubo in the Philippines also brought a few years of cooling.

Scientists hoped to discover if they could artificially produce cooling conditions similar to volcanoes, but without the ozone-damaging effects of sulphur dioxide. 

After studying the chemistry behind the problem, they came up with calcite. The plentiful mineral is found in limestone, and has reflective properties that would help to cool the planet, the researchers said. It also neutralizes the atmospheric acids that damage the ozone layer, making it a sort of aerosol antacid.

Aerosols saving the planet would have been a laughable idea just two decades ago. They once had a bad reputation when it came to the environment. Scientists linked the chlorofluorocarbons in the cans to a growing hole in the ozone layer. The chemical was also found in refrigerators, air conditioners, and other appliances. However, aerosols no longer contain CFCs.

The idea of spraying calcite into the atmosphere to lower surface temperatures may sound cool, but the scientists admit that the geoengineering project could have unintended consequences. 

Carbon dioxide would continue to build up in the atmosphere, the researchers said.

However, studying this and other geoengineering possibilities help scientists learn more about Earth, and think outside the box when it comes to solving environmental problems.

The study was published in the journal <a href="http://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

Could aerosol 'antacids' be the key to global cooling?

The Pacific and Atlantic oceans that surround South America can bring rain or dry weather to the continent. So can the Indian Ocean halfway around the world, a new study found. 

The study, conducted by climate scientists from the <a href="http://www.universidad.edu.uy/">University of the Republic</a> in Uruguay, took a deep look at the Indian Ocean Dipole. The surface temperatures in the eastern and western portions of the Indian Ocean tend to oscillate. The eastern half becomes warmer, then it cools and the western portion warms, and the cycle repeats. 

Because the Indian Ocean is connected with both the Atlantic and the Pacific, the Dipole can influence those oceans, which in turn influence the weather in South America, the study found. 

The scientists collected a vast store of data about the Dipole, along with the Pacific’s El Niño/La Niña oscillation and temperature variability in the tropics and North Atlantic. They used the data to create computer models studying how conditions in each ocean might influence South America’s weather – as well as each other.

The three oceans are connected by both atmospheric and oceanic “teleconnections,” or long-distance but connected climate events, according to the new research. 

They used observations and mathematical modeling to see how oceanic circulation between the Atlantic, Pacific and Indian oceans might affect the climate in South America. They also looked at atmospheric circulation between the three bodies of water.

What they found is that surface temperature anomalies in the tropical Pacific and Atlantic oceans brought rainfall to tropical regions of South America, according to their models.

Another key finding is that, as ocean conditions become more unpredictable, so do weather conditions in the extratropics, areas outside of South America’s tropical regions. The continent’s internal atmospheric changes are a larger player in extratropical weather than the oceans, the researchers said.

That may change if the oceans and Earth’s surface temperatures continue to rise, the scientists said. 

The researchers hope their modeling can be expanded to look at how oceanic anomalies can affect land regions worldwide. They also hope it can be used to predict and plan for some of the effects of climate change, they said.

A London street was underwater Sunday, but it wasn’t torrential rains or rising sea levels that brought the scene of destruction. It was a burst water main – the third in less than a week.

When the main burst just after noon, around 350 people living on Stoke Newington High Street had to evacuate. More than 150 properties suffered damage. 

A similar scene played out on Islington’s Upper Street last week, and there was also a water main break in south London’s Blackheath area on Saturday.

Officials with <a href="https://www.thameswater.co.uk/">Thames Water</a>, the company that maintains the pipes, have launched a full investigation into the water main breaks. At first glance, however, the breaks may be simply due to the pipes’ age.

Many of the pipes in London are 100 years old or older, and without continued investments in replacing old pipe, the system can become fragile, said Bob Collington, director of Thames Water. 

The private water utility  will do its best to make sure customers aren’t stuck with bills for repairing any damage, he said.

Thames Water and the <a href="http://www.london-fire.gov.uk/">London Fire Brigade</a> are working to clean up the spilled water on Stoke Newington High Street. The fire brigade was also using sandbags to try and keep the water outdoors, and retrieving necessary belongings for evacuees. 

Aside from wasting thousands of gallons of water – leaky pipes and water main breaks cost the U.S. alone as much as 6 billion gallons of purified drinking water every day, according to the <a href="http://www.cnt.org/publications/the-case-for-fixing-the-leaks-protecting-people-and-saving-water-while-supporting">Center for Neighborhood Technology</a> – water main breaks can be dangerous to public health. 

Health hazards come not just from the initial flooding, but from toxic mold and mildew that can grow in the walls of flood-stricken homes. Additionally, water main breaks and repairs create temporary openings where contaminants can enter the pipes, according to the <a href="https://www3.epa.gov/">Environmental Protection Agency</a>.

By Sunday evening, the water was receding. The burst main shouldn’t affect water access in the area, Thames Water officials said.

London water main bursts, flooding street

Jia Wenqi has no arms, and Jia Haixia is blind, but that hasn’t kept the two men from taking on a mission: planting trees and reforesting their village in Hebei Province, China. 

That mission was recently captured in a short, 10-minute documentary by <a href="https://www.youtube.com/watch?v=Mx6hBgNNacE">GoPro</a> called <a href="https://gopro.com/goproforacause/brothers">Brothers</a>.

When Wenqi and Haixia were children, the river near their village of Yeli was full of fish and shrimp, and birds and wild rabbits were plentiful, they said.

Then a quarry moved in, removing trees and grass and spreading vast clouds of dust, Wenqi and Haixia said. 

Like their environment, the two men had undergone changes over the years. Neither was born with their current disabilities. Jia Wenqi lost his arms when he touched a power line at the age of three. Jia Haixia was born blind in one eye, but an industrial accident at the quarry took the vision in his other eye.

When Haixia lost his vision, it was frustrating. He could no longer read the newspaper or perform basic tasks, he said. 

That’s when Jia Wenqi stepped in and offers his “sleeve,” Haixia said.

“You’ll be my arms, I’ll be your eyes,” Wenqi told him. 

The childhood friends were determined to find some way to contribute to their community. That’s when they began noticing that the birds were disappearing, and dust from the quarry had choked the river.  

“We asked ourselves, ‘What are we going to do?’” Wenqi said in the short film. “We can’t just be sitting around, useless to society. There weren’t a lot of options for us, but being alive means having a purpose. So we said to each other, ‘Let’s plant trees.’”

Every tree is an air purifier, they noted.

So Wenqi and Haixia began planting trees in 2002. They didn’t have money to buy seeds or saplings, so they took cuttings from the few remaining trees and coaxed them into growing. 

At first they thought planting trees would be easy. They planted 800 trees the first year – but most died from lack of water. Instead of giving up, the two found wet areas where they could plant. 

They’ve planted more than 10,000 healthy trees since they began, and birds have returned to the area to nest in them.

The pair originally planned to cut some of the trees for money while continuing to plant new saplings, they told the <a href="http://www.globaltimes.cn/content/987430.shtml">Global Times</a>. When people began taking notice of their forest and helping the two men support themselves and their families, they no longer needed to sell any trees and it became a moot point. They could turn their work purely into an environmental mission, they said.

The short film of their work, shot with GoPro cameras, was released on YouTube in June, but it recently went viral. It’s racked up nearly half a million views so far. So has a much shorter video by <a href="https://www.youtube.com/watch?v=C2cqQA_zsKY">Great Big Story</a> about the two best friends. 

In both films, the men state their mission: To help the environment and leave a forest for future generations. 

The pair are in good company. In 1977, Wangari Maathai of Kenya founded the <a href="http://www.greenbeltmovement.org/">Green Belt Movement</a>. Her movement focused on environmental conservation, especially through planting trees. 

The Green Belt Movement offered stipends to women who planted seedlings throughout Kenya. Like people with disabilities in China, women in rural Kenya had limited opportunities at the time the movement was founded. But like , those women didn’t let the limitations of their society stop them from doing something meaningful.

“The future of the planet concerns all of us, and we should do what we can to protect it. As I told the foresters, and the women, you don't need a diploma to plant a tree,” Maathai wrote in her autobiography Unbowed.

As of 2012, women in the movement had planted more than 51 million trees, according to <a href="http://www.huffingtonpost.com/jamie-bechtel/wangari-maathai_b_1958853.html">Wanjira Mathai</a>, daughter of Wangari Maathai, who has continued her mother’s work after her death. Wangari Maathai was awarded a Nobel Peace Prize in 2004. 

Other organizations focus on reforestation to build diplomacy, boost marginalized communities, and simply to help the environment. Mature trees can take in up to 48 pounds of carbon dioxide each year. That means that when the 10,000 trees in Yeli, China have matured, they will offset 48,000 pounds of carbon dioxide.

<a href="http://www.plantingpeace.org/">Planting Peace</a> has donated more than 1 million tree seeds since it began its conservation program. They focus on Moringa trees, which not only grow quickly but also sprout leaves that can be harvested and eaten. Most of their seeds are going to Haiti, where deforestation is a massive problem.

<a href="http://www.peacetreesvietnam.org/">PeaceTrees Vietnam</a> offers a program where travelers can work with Vietnamese citizens to reforest parts of the country that are still reeling from decades of warfare. The goal is to build ties between citizens of the two countries while healing the land. 

The <a href="https://www.arborday.org/">Arbor Day Foundation</a> helps plant trees around the world, repairing forests after natural disasters or man-made deforestation.

There are also groups like <a href="http://www.treesforthefuture.org/">Trees for the Future</a>, which provides people living in poverty with a “forest garden,” including fruit trees, to help repair degraded farm land and provide a source of income.

“It’s the little things citizens do. That’s what will make the difference. My little thing is planting trees,” Wangari Maathai once said. 

In the GoPro documentary, Jia Wenqi unintentionally echoed her.

“If everyone planted one or two trees a year, imagine the difference we could make,” Jia Wenqi said.

GoPro plans to begin collecting donations to help Jia Wenqi and Jia Haixia in their forest-building mission soon, the company said.

Men on a mission: disabilities don't keep pair from planting trees in China

Great Britain has a very effective tool in the fight against greenhouse gas emissions: wind farms.

So claims a new study that analyzed how much power was generated by wind farms and used throughout England, Scotland, and Wales, and calculated how that reduced greenhouse gas emissions. 

The study, conducted by engineers from the <a href="http://www.ed.ac.uk/">University of Edinburgh</a>, found that the wind farms prevented the creation of nearly 40 million tons (36 million metric tons) of greenhouse gases over six years. 

That blows away government estimates of how effective the wind farms would be at cutting pollution by millions of tons, the researchers said. 

The study was the first to use real data instead of estimates, the researchers said. They analyzed the <a href="https://www.nationalgridus.com/">National Grid</a>, looking at energy output from the wind farms between 2008 and 2014, in half-hour increments. 

It was also the first to study the impact of wind farms on energy production in Great Britain, said lead author Dr. Camilla Thomson. 

Energy in Great Britain comes from a mix of sources, so when energy production from the wind farms increases, output from more traditional sources like coal and natural gas decreases. The researchers took that into account when calculating the wind farms’ effect on carbon emissions. 

Their research suggests that investment in more wind turbines could help the UK meet its goals for reducing carbon emissions, the engineers said.

While Thomson’s research was the first to study wind turbine energy production’s effect on emissions in Great Britain, wind energy has proven a valuable asset in providing clean energy elsewhere. 

In California, three wind farms produce enough electricity each year to power a city the size of San Francisco, according to the <a href="http://www.energy.ca.gov/">California Energy Commission</a>. One of them, the Alta Wind Energy Center in Kern County, is the largest on-shore wind farm in the U.S. and third largest in the world.

Texas beats California for the most wind-generated power in the U.S. A windy day in December 2015 helped the state break a major record: wind provided 45 percent of the state’s energy for a short time, according to <a href="https://blogs.scientificamerican.com/plugged-in/texas-sets-new-all-time-wind-energy-record/">Scientific American</a>. 

China has gone on a wind turbine building frenzy in recent years, and now builds two turbines every hour, double the United States. However, the country’s power grid prioritizes energy from coal plants, so the massive wind farms are unused 15 percent of the time, the <a href="http://www.bbc.com/news/science-environment-37409069">BBC</a> said. The country has continued to build new coal plants even as it invests heavily in wind and solar power.

Great Britain has the three biggest offshore wind farms in the world, and another seven in the top 25.

Bill Gates, alongside a dream team of the some of the world’s wealthiest men, will spearhead a $1 billion fund to invest in green energy. The group of backers also includes Sir Richard Branson, Alibaba founder Jack Ma, and Amazon founder Jeff Bezos, boasting a combined net worth of over $171 billion.

This week, the team of investors launched<a href="http://www.b-t.energy"> Breakthrough Energy Ventures</a> (BEV), which aims to invest $1 billion in green energy over the next 20 years. The initiative began brewing last year at the <a href="http://www.cop21.gouv.fr/en/">Paris Climate Summit</a>, and plans to take a more long-term, nuanced approach to backing affordable and reliable green energy sources. The BEV fund will began making investments in 2017.

Said Gates, "Our goal is to build companies that will help deliver the next generation of reliable, affordable, and emissions-free energy to the world. I am honored to work along with these investors to build on the powerful foundation of public investment in basic research."

Afters Gates left Microsoft in 2014, he has made a new career in philanthropy and has already invested several clean energy initiatives. 

As Gates told <a href="http://qz.com/859860/bill-gates-is-leading-a-new-1-billion-fund-focused-on-combatting-climate-change-through-innovation/">Quartz</a>, “Anything that leads to cheap, clean, reliable energy we’re open-minded to."

Gas trader John Arnold is another backer of Breakthrough Energy Ventures. Arnold believes that because prior clean energy investors have seen small returns, there is now a shortage of funding for green energy technology. 

"The dearth of venture funding for clean energy technologies threatens to create a valley of death for the industry, with emerging ideas unable to find the necessary capital to reach commercialisation," said Arnold. “As an investor-led effort, Breakthrough Energy Ventures is designed as a source of patient capital to spur innovation to meet the growing demand for low-cost, clean energy solutions."

The Dieselgate scandal is still making waves in the automobile industry more than a year after it entered the public consciousness. Now, <a href="http://www.volkswagen.co.uk/">Volkswagen UK</a> has reported a drop in its market share – and is warning of potential legal threats.

Dieselgate began in 2013, when researchers from <a href="https://www.wvu.edu/">West Virginia University</a> and the <a href="http://www.theicct.org/">International Council on Clean Transportation</a> began noticing that Volkswagen vehicles often had different nitrogen oxide emissions during lab testing than in road tests. Nitrogen oxide is a byproduct of vehicle fuel use.

They shared their findings with the <a href="https://www3.epa.gov/">Environmental Protection Agency</a>, which confronted Volkswagen. After several rounds of back and forth accusations and denials, Volkswagen admitted in September 2015 that it <a href="https://www.bloomberg.com/news/articles/2015-09-18/epa-says-volkswagon-software-circumvented-car-emissions-testing">cheated on U.S. emissions tests</a>. The tampering affected both Volkswagen and Audi cars, it said.

Last month, California regulators found an additional software program in the Audi cars that also falsifies carbon dioxide readings, according to the <a href="http://www.wsj.com/articles/volkswagen-probe-in-germany-extended-to-chairman-1478429066">Wall Street Journal</a>. 

In the United Kingdom, the ongoing and widening Dieselgate scandal could spell more trouble for the automaker. Volkswagen has already settled the nitrogen oxide tampering case in the U.S. for $15 billion, according to <a href="http://www.pbs.org/newshour/rundown/volkswagen-settles-emissions-scandal-15-billion/">PBS NewsHour</a>.

<a href="https://www.gov.uk/government/organisations/companies-house">Companies House</a> has warned that accounts filed for the year ending in December 2015 warned of lawsuits filed against the car company’s UK branch. No lawsuits have yet been served. 

UK drivers are angry that they weren’t offered the same compensation packages U.S. customers were, officials said.

A modification created by Volkswagen ensures that their vehicles meet emissions standards, but only 10 percent of UK drivers have upgraded their cars, officials said.

Volkswagen UK has taken a hit. Costs related to stocking the equipment to upgrade vehicles are expected to total around £13 million. Market share has slipped by nearly a percentage point, from 20.3 percent to 19.5, officials said.

Nearly 23 percent of greenhouse gas emissions in the UK are from transportation sources, according to <a href="https://www.gov.uk/government/statistics/final-uk-greenhouse-gas-emissions-national-statistics-1990-2014">a 2014 survey</a>. That includes automobiles. Many climate scientists believe greenhouse gases contribute to climate change.

Scientists are studying data from five satellites over two decades to get a better sense of how Antarctic glaciers are retreating.

They’ve discovered something interesting: the melting glaciers are shrinking at different rates, even when they’re in the same location.

In fact, some of the glaciers are thinning at three times the rate of their neighbors, the scientists said.

The researchers, led by Dr. Hannes Konrad, focused primarily on six Antarctic glaciers that flow into the Amundsen Sea: Pine Island, Thwaites, Haynes, Pope, Smith, and Kohler. 

The Pine Island Glacier is known to be contributing more to rising sea levels than the others, the agency said.

Warming ocean waters cause the glaciers to thin and melt more quickly, Konrad said. Where glaciers meet the sea, a portion of the ice shelf floats. Water causes that floating portion to melt, and ice flows from the upper part of the glacier to replace what is lost to melt, Konrad said. 

Warmer water melts the floating portion of the glacier more quickly, he said. Then the glacier thins as ice flows toward the water faster than it can be replenished by snow.

Scientists from the <a href="http://www.cpom.org/">Centre for Polar Observation</a> in the UK examined data going back to 1992 from the <a href="http://www.esa.int/">European Space Agency’s</a> ERS-1, ERS-2, Envisat and CryoSat, along with <a href="https://www.nasa.gov/">NASA’s</a> IceSat.

They found that all of the Amundsen Sea glaciers thinned during that time. However, in some cases that thinning was erratic. For example, thinning of the Thwaites Glacier stopped entirely for four years, while the neighboring Pine Island Glacier continued to thin drastically. 

The variations could be accounted for by several different conditions, Konrad said. Topography, hydrology, glacier catchment size, and even the bedrock could alter how quickly the glaciers melt, he said.

The scientists hope to use the data to better calculate sea level rise and glacial retreat. That analysis will improve modeling of how Antarctic glaciers may continue to thin and melt, the researchers said. 

The study was presented at the <a href="https://sites.agu.org/">American Geophysical Union’s</a> fall meeting in San Francisco, California.

Today, the town of Blythe, California is in an inland desert. It’s a far cry from 5 million years ago, when the geological record of ancient ocean tides shows the Colorado River flowed into the Gulf of California in that place, according to a new study.

A team of <a href="http://uoregon.edu/">University of Oregon</a> geologists traveled to the town near the Arizona border to study the sedimentary rock along valley that houses the Colorado River. 

They found that Blythe was once beachfront property. The layers of sediment aren’t even. Instead, the layers vary rhythmically, pointing to tides ebbing and flowing and shifting the sediment deposits in the process, the researchers said.

A number of the desert rocks near Blythe, particularly the Bouse Formation. The rock formation is awash with tidal features, according to geologists. They’ve long suspected that the Bouse Formation would hold clues to prehistoric water flows in the region.

Now, the new research shows it was probably once underwater – specifically, under the northern end of the Gulf of California, which now begins south of the U.S-Mexico border.

Previously, scientists believed that it was under one of a series of freshwater lakes, said Brennan O’Connell, a graduate student at the University of Oregon and lead author of the study. The new evidence of the motion of ancient ocean tides in the layers of rock is one of just several clues indicating the gulf once stretched much farther north.

Another piece of evidence that’s in the geological record: uplift, the slow, vertical raising of the Earth’s surface, the researchers said. The former sea floor is approximately 1,082 feet higher these days than it was 5 million years ago, O’Connell said. 

The new geological study confirms a theory paleontologists have put forward for years. The fossil record experts have found remnants of saltwater creatures in the area for more than 50 years, but geologists who supported the freshwater lake hypothesis believed birds of prey must have carried them to the region, the researchers said. The new evidence that the saltwater gulf stretched from the ocean north to the Blythe area fits better with that fossil record.

Sedimentary deposits look very different when ocean tides play a role in their formation versus lake waters, the researchers said. They also used mathematical analyses to back up their findings.

The study was shared online and will be published by the journal <a href="http://geology.com/">Geology</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.

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.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the importance of monitoring the shape of the sea surface, which is constantly changing. These observations have many applications, such as ship routing, <a href="https://www.earth.com/news/the-modem-ocean-is-a-tough-place-for-whales-to-survive/">ocean</a> current forecasting, and debris tracking.



"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.
