Humanity faces an urgent need for change to prevent biodiversity loss and the continued destruction of our planet. The UN biodiversity expert panel's latest "transformative change" report highlights the dire need for radical societal shifts.



Released Wednesday by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the report calls for immediate action to address overconsumption, wealth concentration, and humanity's growing disconnection from nature.



"It is not just governments. It is not just business. It is not just civil society. It is all of us. We all need to work together," said Arun Agrawal, one of the report’s lead authors.



While transformative action may seem challenging, the report emphasizes that it is achievable. Here’s a closer look at three inspiring examples of successful transformations from around the world.



<h2 class="wp-block-heading" id="h-reviving-marine-ecosystems-os-minarzos-model">Reviving marine ecosystems: "Os Minarzos" model</h2>



In 2002, Spain suffered a severe ecological disaster when the Prestige oil tanker broke apart, spilling massive amounts of oil into the Atlantic Ocean. 



This environmental catastrophe devastated Galicia's coastline, causing significant <a href="https://www.earth.com/news/polar-light-sustains-biodiversity-over-millions-of-years/" target="_blank" rel="noreferrer noopener">biodiversity</a> loss and severely affecting marine life and the livelihoods of local fishing communities.



In response, the communities in Galicia decided to adopt a new approach to marine reserve management, called the "Os Minarzos" model.



<h2 class="wp-block-heading" id="h-advantages-of-the-model">Advantages of the model</h2>



This innovative strategy brought together fishers, scientists, and local authorities to collaboratively restore and protect the marine ecosystem. 



The model emphasized sustainable fishing practices, scientific guidance, and community involvement - promoting cooperation among all stakeholders.



Although the transition faced challenges, including initial disagreements and tensions, the initiative became a long-term success. 



Over time, the "Os Minarzos" model led to healthier marine ecosystems, improved fishing practices, and increased <a href="https://www.earth.com/news/new-solutions-for-the-climate-and-biodiversity-crisis/" target="_blank" rel="noreferrer noopener">biodiversity</a>. Local fishers also experienced higher incomes, while trust and cooperation within the community strengthened significantly.



The model’s impact extended far beyond Galicia. It inspired international guidelines for sustainable marine management and influenced networks of over 20 million fishers across Europe and the Americas. 



<h2 class="wp-block-heading" id="h-technology-to-prevent-biodiversity-loss">Technology to prevent biodiversity loss</h2>



In China, the Ant Forest mobile application has become a <a href="https://www.earth.com/news/urban-biodiversity-is-not-a-luxury-it-is-attainable-for-everyone/" target="_blank" rel="noreferrer noopener">powerful tool</a> for promoting eco-friendly habits and environmental restoration. 



Launched in 2016, this innovative app encourages users to adopt sustainable behaviors, such as walking or cycling instead of driving, and cutting down on plastic and paper usage. 



For every eco-friendly action, users earn "green energy points" in the app, which accumulate to grow a virtual tree. Each virtual tree is then matched with the planting of a real tree.



The initiative has made a significant impact. Since its inception, Ant Forest has planted an astounding 548 million trees across 13 provinces in China. This reforestation effort not only helps combat climate change but also addresses environmental degradation in vulnerable areas.



Beyond its environmental benefits, the project has also provided economic opportunities. It has created jobs in eco-agriculture and ecotourism, particularly in rural regions struggling with environmental challenges. 



<h2 class="wp-block-heading" id="h-community-led-conservation">Community-led conservation</h2>



The <a href="https://www.nashulai.com" target="_blank" rel="noreferrer noopener">Nashulai Maasai Conservancy</a> in Kenya is a pioneering example of how traditional knowledge and community engagement can drive effective <a href="https://www.earth.com/news/what-are-the-biggest-drivers-of-biodiversity-loss/" target="_blank" rel="noreferrer noopener">conservation</a>. 



This initiative blends the wisdom of indigenous practices with modern approaches to tackle multiple challenges, including species protection, income generation, and climate change mitigation.



The conservancy adopts a holistic strategy by establishing community-managed protected areas. These areas not only safeguard wildlife and combat biodiversity loss but also involve local communities in activities like river cleaning and tree planting. 



Such efforts improve environmental health while addressing the needs of the people living in the region.



This collaborative approach has transformed Nashulai into a thriving habitat where both humans and wildlife coexist harmoniously. By empowering local communities and integrating ecological restoration with socio-economic benefits, Nashulai exemplifies how conservation can work in harmony with human development.



"Over a very short period of time, biodiversity reappeared," said Karen O’Brien, another lead author of the report. "The power of community, again and again in our examples, is important."



<h2 class="wp-block-heading" id="h-addressing-biodiversity-loss">Addressing biodiversity loss</h2>



The <a href="https://www.un.org/en/" target="_blank" rel="noreferrer noopener">UN</a> report highlights the interconnectedness of ecological, social, and economic challenges - offering a blueprint for action.



Addressing biodiversity loss and ecosystem collapse requires collective effort. "It is all of us. We all need to work together," said Agrawal.



These stories from Galicia, China, and Kenya show that transformation is not only possible but can yield tangible benefits. 



Whether through community-driven conservation, innovative technology, or collaborative governance, humanity has the tools to make a <a href="https://www.earth.com/news/animal-tracking-is-crucial-for-preserving-biodiversity/" target="_blank" rel="noreferrer noopener">difference</a>. The question is whether or not we will rise to the challenge.

UN report calls for global change to stop biodiversity loss

Humanity faces an urgent need for change to prevent biodiversity loss and the continued destruction of our planet. The UN biodiversity expert panel's latest "transformative change" report highlights the dire need for radical societal shifts. Released Wednesday by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the report calls for immediate action to address overconsumption, wealth concentration, and humanity's growing disconnection from nature.

New York City Waters Transform Into Serene Wetlands. Amid the crammed concrete and steel of Brooklyn, a ribbon of clear water stretches out into a vast bay. Tall grass rustles along the undulating shoreline, where bursts of golden flowers, pines and cacti flourish in the soft sand.
"This is what would have been here pre-us. Pre-European development," said John McLaughlin, director of the office of ecological services at New York City's department of environmental protection.
Just a few years ago, the new york city waters, known as Paerdegat Basin, was a fetid mess. The water was murky green, teeming with 1.8 billion gallons of sewage and rainwater that streamed in during storms. The working-class neighborhoods along the waterway stank like an outhouse during hot weather and low tide. The shoreline was strewn with rusted out cars, garbage and broken bottles.
"It was a junkyard. It was a chop shop," McLaughlin said. "It was a weed-strewn mess, full of invasive plant life. And boy, did it smell."
The Paerdegat tributary feeds directly into Jamaica Bay, a body of water and marsh sandwiched between Brooklyn and Queens, and on the shores of which sits Kennedy International Airport. Part of the area is run by the city; the other is Gateway National Recreational Area, which contains a wildlife refuge with one of the most important bird sanctuaries in the Northeast.
And now a decade-long $455 million investment by the city to clean up Paerdegat Basin is nearly complete, including a new sewage overflow retention facility at the head of the 1.3-mile-long channel and 52 restored acres of native grasslands and wetlands.
In older cities like New York, sewer systems are built on one pipe that handles both rainwater and sewage. With considerable concrete and not enough exposed earth to absorb rainwater, the combined runoff often overflows and backs into city waterways.
The new retention facility is capable of preventing 50 million gallons of wastewater per storm that would previously have streamed into the water and out to the bay. It was completed first and has been operational since 2011. Automated, state-of-the-art machinery clicks on when water levels rise too high. Giant rakes segregate large sticks, bottles and other refuse from the pooling wastewater, which is then collected and stored in giant underground tanks. After the storm subsides, the water is pumped out to a treatment facility and cleaned, and sent out the waterways.
The facility is spotless. Even the air is filtered, so there's no smell.
"That's the best compliment you can give us," said Chris Laudando, the chief of collections facilities for southern Brooklyn.
It has reduced the amount of wastewater spilling into the channel from 1.8 billion gallons annually to about 650 million, said Vincent Sapienza, deputy commissioner of the Department of Environmental Protection. That means better water quality in the basin and out to the bay and a better <a href="http://www.earth.com/news/top-predators-face-the-most-imminent-threat-from-habitat-loss/">habitat</a> for birds and fish that live there.
The idea for the project was first discussed in the mid-1990s, but took until 2005 to get off the ground. Conservationists have praised the project as forward-thinking and inclusive. Dan Mundy of the Jamaica Bay Ecowatchers, a watchdog group for Jamaica Bay and its tributaries, said he has noticed a visible change in the bay.
"We're very excited," he said. "I think it's a big deal, the work that went into the project is paying off and now it's an area really to be enjoyed."
The construction on the channel began after the retention facility. Crews dredged the filthy sediment and cleared the shoreline of refuse, then used sand excavated for the retention facility to form the hills. The department of environmental protection planted more than 100,000 plugs of grassland and wildflowers, more than 5,300 shrubs and nearly 1,100 trees.
Then, they waited for the fragile seedlings to grow. The result is a mass of soft golds and greens that reflect off the water. Goldenrod and smooth cord grass are now about waist-high. Atlantic white cedars grow among little blue stem, American holly and the eastern prickly pear- the only cactus native to the Northeast. McLaughlin said he used historical biology records to decide what to plant. New York City Waters Transform Into Serene Wetlands
"It's very satisfying to see a project you've been talking about since the '90s come into being," he said.
The department of environmental protection will turn the acreage over to the city parks department in the upcoming months, and it will remain closed to give plants enough time to take proper root. Five acres will eventually be open for educational tours as an ecology park, and the rest will stay natural to encourage wildlife growth, though no opening date has been set.

Study: Only 4 Percent Of The Ocean Is Protected. Despite global efforts to increase the area of the ocean that is protected, only four percent of it lies within marine protected areas (MPAs), according to a University of British Columbia study.

UBC Institute for Ocean and Fisheries researchers found that major swaths of the ocean must still be protected to reach even the most basic global targets.

In 2010, representatives from nearly 200 countries met in Nagoya, Japan, and adopted the United Nations' Aichi Targets, in a bid to stem the rapid loss of biodiversity. The countries committed to protecting at least 10 per cent of the ocean by 2020.Study: Only 4 Percent Of The Ocean Is Protected

"The targets call for much more than just 10 per cent protection," said lead author Lisa Boonzaier. "They require that protected areas be effectively and equitably managed, ecologically representative and well-connected, all of which will help to ensure that MPAs contribute to more than percentage targets and meet the goal of conserving biodiversity."

Boonzaier believes that not only do countries need to create more MPAs, they need to improve the protection they afford biodiversity by making a greater percentage of them no-take and enforcing them as such.

"No-take" marine protected areas are zones where it is prohibited to extract any resources, including living resources, such as fish, crustaceans, and seaweed, and non-living resources, such as oil and gas. Only 16 per cent of the area that is protected or 0.5 per cent of the global ocean--is designated as "no take."

However, the past decade has seen improvement. In 2006, only an estimated 0.65 per cent of the ocean was protected.

"Given the creation of very large marine protected areas in recent years, notably though the Global Ocean Legacy Project of the Pew Charitable Trusts, there is a chance that the Aichi Targets can be reached, which would be a major achievement," said co-author Daniel Pauly, a professor at the Institute for Ocean and Fisheries.

Climate Change Will Bring More Harmful Algal Blooms. Marine scientists attending an international workshop warned that the future may bring more harmful algal blooms (HABs) that threaten wildlife and the economy, and called for changes in research priorities to better forecast these long-term trends.

The findings of the international workshop on HABs and climate Change were published Friday in the journal Harmful Algae. The workshop was organized under the auspices of the North <a href="https://www.earth.com/image/noumea-in-the-south-pacific-archipelago-of-new-caledonia/">Pacific</a> Marine Science Organization (PICES) and the Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB) and endorsed by the International Council for the Exploration of the Sea (ICES). The central findings were that while there are reasons to expect HABs to increase with climate change, poor scientific understanding seriously limits forecasts, and current research strategies will not likely improve this capacity. Climate Change Will Bring More Harmful Algal Blooms

Empirical observations suggest cause for grave concern. Northward expansion of phytoplankton species, wider seasonal windows for HAB development, and an increasing prevalence of HABs worldwide all indicate a future with greater problems.

The impacts of algal blooms are extensive. Although phytoplankton blooms normally fuel productive ecosystems, some blooms create very low oxygen concentrations in bottom waters, killing or driving out marine fish or benthic organisms. Others produce potent neurotoxins that threaten ecosystems and human health.

Evidence suggests that these destructive blooms, called red tides in the past but more properly "harmful" algal blooms, are increasing in frequency and severity, possibly from human causes. "There is growing concern among scientists that climate change may exacerbate this trend," said Prof. Mark Wells, University of Maine and organizer of the workshop. "We are frustrated by the inadequate national research focus to determine the likelihood of these worst-case scenarios."

The combined effects of increasing temperature and atmospheric CO2 are affecting ocean surface temperatures, nutrients, light, and ocean water acidity, all of which affect marine ecosystems. These factors influence not just the intensity of algal blooms but also their composition. The question is whether climate change will enable harmful species to outcompete other phytoplankton. "It is critically important that we learn as much as possible, as precisely as possible, to fill the critical gap in knowledge between the current and the future phytoplankton community structure," says Professor Charles Trick, Western University, Canada.

The challenge is that the mechanisms driving the development of most HABs are only partially understood. "We need to build on and link our patchwork knowledge of HABs to the forecast patterns of climate change if we are to better prepare society for future HAB scenarios," said Wells.

The intense toxic phytoplankton blooms off the west coast of North America this summer appear to be associated with unusual warming-related conditions. "Does this large scale harmful algal bloom provide a window into the future?" said Dr. Vera Trainer of NOAA Fisheries' Northwest Fisheries Science Center. "While it still is unclear, there is reason for substantial concern."

The workshop participants developed several urgent recommendations on research priorities. These include re-orientating research to study how harmful species interact in planktonic communities, focus more intensive study on key organisms, emphasize developing ecological and forecast models, and strengthen linkages among global, national and regional observation programs.

"Past research has brought great understanding of individual HAB organisms; future work must concentrate on how these harmful species fit into their ecosystems. It is the most significant coastal challenge facing society today," said Trick.

Although workshop participants were optimistic, they urged fundamental shifts in HAB research so that science can better inform public debate over climate change effects on the oceans, rather than just seeking to explain destructive patterns after they develop.

Study: Global Warming Could Still Be Limited To Only 2 Degrees Celsius.They study conclude that effectively limiting climate change is possible if a major economy acts as a forerunner, while other nations follow -- and, importantly, by doing so they do not have to agree on common criteria for fairness.

"If either the European Union or the US would pioneer and set a benchmark for climate action by others, the negotiation logjam about fair burden sharing could be broken," lead author Malte Meinshausen from the Potsdam Institute for <a href="https://www.earth.com/news/experts-have-outlined-the-top-ten-climate-insights-of-2020/">Climate</a> Impact Research and the University of Melbourne says. "Our analysis shows that they would have to roughly double their current domestic 2030 emissions reductions targets -- which would certainly require substantial efforts. Yet it seems to be one of the few options to stay on track for eventually limiting warming below 2 degrees <a href="https://www.bing.com/search?q=Celsius&amp;cvid=9c83945212f34c8faaffc7c3fe8ecf3c&amp;FORM=ANAB01&amp;PC=HCTS">Celsius</a> and fend off a drastic increase of weather extremes and sea-level rise.Study: Global Warming Could Still Be Limited To Only 2 Degrees Celsius

Two conflicting fairness criteria must be dealt with

While the UN Climate Change Convention holds up the formula of 'common but differentiated responsibility', the world is currently divided into two main camps, simply speaking. One is in favor of distributive justice at some point in the future: emissions per person would be roughly same in every country by 2050. This includes the EU and the USA. The other camp, with China and India, calls for corrective justice: the emissions of the past should be taken into account to achieve equal cumulative emissions per person. This kind of fairness scheme would mean that those that emitted less in the past can emit more in the future on a per-capita basis.

Analyses of emissions reduction pledges and past negotiations show that, unsurprisingly, countries tend to adhere to the allocation principle which allows them to least reduce emissions, compared to their international competitors. Since China and India industrialized only recently, in the past they emitted less than the EU and the US did. Yet today China emits more than the EU and US combined on an absolute basis, and about the same as the EU on a per-capita basis.

'This seems less utopian than a uniform regulation'

"Now we have calculated how much a major economy would have to cut its greenhouse gas output if all the other countries would follow the emissions allocation scheme that is most favourable to them -- so some base their reduction number on the equal per capita scheme, others include the historical emissions, and still the 2-degree limit is met," says co-author Louise Jeffery from the Potsdam Institute. The scientists call this concept diversity-aware leadership. "This seems less utopian than a uniform regulation," says Jeffery. "But it builds on the assumption that most economically relevant countries participate in one way or another and ensures that the global efforts are successful in limiting warming to 2°C."

In this scenario, the US national emissions reduction target would have to be roughly 50 percent instead of currently 22-24 percent below 2010 levels by 2030. Alternatively, the equivalent target for the EU would have to be about minus 60 percent instead of currently 27 percent below 2010 (27% below 2010 being equal to the announced 40% below 1990 target).

It's in the numbers: China will not take the lead

China could also take the lead, but beyond political considerations already the numbers show that this is unlikely. In fact, the quantification of the Chinese pledge indicates the largest gap between a leadership target and a currently proposed peaking by 2030. If China wanted to assume leadership, China would have to reduce emissions by 32 percent below 2010 levels by 2030. In a scenario of equalized cumulative per-capita emissions, it would only need to reduce them by 4 percent. This seems little, but would in fact be a most crucial contribution.

"If you look at what pledges the countries put on the table for Paris so far, it's clearly not enough to keep warming within the internationally agreed 2-degree limit -- hence the current 'intended nationally determined contributions' can only be regarded as a first step in the right direction," says co-author Sebastian Oberthuer from Vrije Universiteit Brussel. Based on IPCC databases, the scientists derived their proposition which is contrary to previous assumptions about allocation schemes. "If we postpone action until we have universal agreement on a fair allocation of emissions reductions," he says, "the result will be fair only in that everybody will lose -- because climate change will hit us all."

"Our study thus anticipates the upcoming Paris climate summit, which will see countries make their mitigation contributions in an independent bottom-up manner," says Joeri Rogelj from the International Institute for Applied Systems Analysis. "This is a fundamental break with the past," he says, "and in this new landscape, our study introduces an important new concept which helps us understand how major countries can still assume a leadership role on this highly fragmented playing field.

Republican Congress Moves To Block Obama's Clean Power Plan. Congressional Republicans are moving to block President Barack Obama's clean power plan to force steep cuts in greenhouse gas emissions from U.S. power plants.
Senate Majority Leader Mitch McConnell and Rep. Ed Whitfield say they will file resolutions early this week opposing Obama's plan to impose new regulations on new and existing coal-fired plants.
The two Kentucky Republicans were expected to file the challenges filed under the little-used Congressional Review Act, which allows Congress to block executive actions with simply majority votes. The maneuver is subject to a presidential veto and has rarely been successful in overturning executive branch rules.
Still, it allows opponents to set up votes calculated to embarrass the Obama administration ahead of international climate talks in Paris this fall.
Republican senators are expected to tout the congressional challenge in a series of floor speeches starting Tuesday. One notable exception is New Hampshire Sen. Kelly Ayotte, who became the first GOP senator to support Obama's sweeping regulation that mandates carbon emissions cuts from the nation's power plants.
Ayotte, who is locked in a difficult re-election fight, said Sunday that the Clean Power Plan would "address climate change through <a href="http://www.earth.com/news/clean-energy-should-be-prioritized-during-covid-19-recovery/">clean-energy</a> solutions that will protect our environment."
New Hampshire is already well on its way to meet the plans' goals, Ayotte said, adding that she would monitor the plan to ensure it does not have an adverse impact on state energy costs.
McConnell said in a statement that the regulations being imposed under the Clean Power Plan "make it clearer than ever that the president and his administration have gone too far - and that Congress should act to stop this regulatory assault."
The administration's "crusade for ideological purity" threatens the livelihoods of coal miners and their families in Kentucky and other states, McConnell said. Republican Congress Moves To Block Obama's Clean Power Plan
"These are Kentuckians who just want to work, provide for their families and deliver the type of low-cost energy that attracts more jobs to Kentucky. And coal is what allows so many of them do all that," he said.
The congressional resolutions follow court challenges filed Friday by industry groups and states dependent on fossil fuels. The challenges from all but two of the 25 states were filed by Republicans. They deride the plan as an "unlawful power grab by Washington bureaucrats" that will kill coal mining jobs and drive up electricity costs.
The Obama administration and environmental groups counter that the rules are needed to cut carbon emissions while curbing the worst impacts of climate change and sea-level rise. They also say the plan will spur new clean-energy jobs.
The new rules require states to cut carbon emissions by 32 percent by 2030, based on emissions in 2005. Each state has a customized target and is responsible for drawing up an effective plan to meet its goal.
The EPA says it has authority to enact the plan under the Clean Air Act.

China could also take the lead, but beyond political considerations already the numbers show that this is unlikely. In fact, the quantification of the Chinese pledge indicates the largest gap between a leadership target and a currently proposed peaking by 2030. If China wanted to assume leadership, China would have to reduce emissions by 32 percent below 2010 levels by 2030. In a scenario of equalized cumulative per-capita emissions, it would only need to reduce them by 4 percent. This seems little, but would in fact be a most crucial contribution.

"If you look at what pledges the countries put on the table for Paris so far, it's clearly not enough to keep warming within the internationally agreed 2-degree limit -- hence the current 'intended nationally determined contributions' can only be regarded as a first step in the right direction," says co-author Sebastian Oberthuer from Vrije Universiteit Brussel. Based on IPCC databases, the scientists derived their proposition which is contrary to previous assumptions about allocation schemes. "If we postpone action until we have universal agreement on a fair allocation of emissions reductions," he says, "the result will be fair only in that everybody will lose -- because climate change will hit us all."

"Our study thus anticipates the upcoming Paris climate summit, which will see countries make their mitigation contributions in an independent bottom-up manner," says Joeri Rogelj from the International Institute for Applied Systems Analysis. "This is a fundamental break with the past," he says, "and in this new landscape, our study introduces an important new concept which helps us understand how major countries can still assume a leadership role on this highly fragmented playing field.

Ancient Permafrost Quickly Transforms To Carbon Dioxide Upon Thawing. Researchers from the U.S. Geological Survey and key academic partners including the University of Colorado Boulder have quantified how rapidly ancient permafrost decomposes upon thawing and how much carbon dioxide is produced in the process.

Huge stores of organic carbon in permafrost soils -- frozen for hundreds to tens of thousands of years across high northern latitudes worldwide -- are currently isolated from the modern day carbon cycle. However, if thawed by changing climate conditions, wildfire, or other disturbances, this massive carbon reservoir could decompose and be emitted as the greenhouse gases carbon dioxide and methane, or be carried as dissolved organic carbon to streams and rivers.

"Many scientists worldwide are now investigating the complicated potential end results of thawing permafrost," said Rob Striegl, USGS scientist and study co-author. "There are critical questions to consider, such as: How much of the stored permafrost carbon might thaw in a future climate? Where will it go? And, what are the consequences for our climate and our aquatic ecosystems?"

At a newly excavated tunnel operated by the U.S. Army Corps of Engineers near Fairbanks, Alaska, a research team from USGS, CU-Boulder and and Florida State University set out to determine how rapidly the dissolved organic carbon from ancient (about 35,000 years old) "yedoma" soils decomposes upon soil thaw and how much carbon dioxide is produced.

Yedoma is a distinct type of permafrost soil found across Alaska and Siberia that accounts for a significant portion of the permafrost soil carbon pool. These soils were deposited as wind-blown silts in the late Pleistocene age and froze soon after they were formed.

"It had previously been assumed that permafrost soil carbon this old was already degraded and not susceptible to rapid decomposition upon thaw," said Kim Wickland, the USGS scientist who led the team.

The researchers found that more than half of the dissolved organic carbon in yedoma permafrost was decomposed within one week after thawing. About 50 percent of that carbon was converted to carbon dioxide, while the rest likely became microbial <a href="http://www.earth.com/news/woody-biomass-neutral/">biomass</a>.

"What this study adds is that we show what makes permafrost so biodegradable," said Travis Drake, the lead author of the research. "Immediately upon thaw, microbes start using the carbon and then it is sent back into the atmosphere." Drake was both a USGS employee and a master's degree student at CU-Boulder during the investigation.

The researchers attribute this rapid decomposition to high concentrations of low molecular weight organic acids in the dissolved organic carbon, which are known to be easily degradable and are not usually present at high concentrations in other soils.

These rates are among the fastest permafrost decomposition rates that have been documented. It is the first study to link rapid microbial consumption of ancient permafrost soil-derived dissolved organic carbon to the production of carbon dioxide.

An important implication of the study for aquatic ecosystems is that dissolved organic carbon released by thawing yedoma permafrost will be quickly converted to carbon dioxide and emitted to the atmosphere from soils or small streams before it can be transported to major rivers or coastal regions.

Ancient Permafrost Quickly Transforms To Carbon Dioxide Upon Thawing. Researchers...

Republican Congress Moves To Block Obama's Clean Power Plan. Congressional Republicans are moving to block President Barack Obama's clean power plan to force steep cuts in greenhouse gas emissions from U.S. power plants.
Senate Majority Leader Mitch McConnell and Rep. Ed Whitfield say they will file resolutions early this week opposing Obama's plan to impose new regulations on new and existing coal-fired plants.
The two Kentucky Republicans were expected to file the challenges filed under the little-used Congressional Review Act, which allows <a href="http://www.earth.com/news/congress-moves-again-to-prevent-obama-from-protecting-water-quality/">Congress</a> to block executive actions with simply majority votes. The maneuver is subject to a presidential veto and has rarely been successful in overturning executive branch rules.Republican Congress Moves To Block Obama's Clean Power Plan
Still, it allows opponents to set up votes calculated to embarrass the Obama administration ahead of international climate talks in Paris this fall.
Republican senators are expected to tout the congressional challenge in a series of floor speeches starting Tuesday. One notable exception is New Hampshire Sen. Kelly Ayotte, who became the first GOP senator to support Obama's sweeping regulation that mandates carbon emissions cuts from the nation's power plants.
Ayotte, who is locked in a difficult re-election fight, said Sunday that the Clean Power Plan would "address climate change through clean-energy solutions that will protect our environment."
New Hampshire is already well on its way to meet the plans' goals, Ayotte said, adding that she would monitor the plan to ensure it does not have an adverse impact on state energy costs.
McConnell said in a statement that the regulations being imposed under the Clean Power Plan "make it clearer than ever that the president and his administration have gone too far - and that Congress should act to stop this regulatory assault."
The administration's "crusade for ideological purity" threatens the livelihoods of coal miners and their families in Kentucky and other states, McConnell said.
"These are Kentuckians who just want to work, provide for their families and deliver the type of low-cost energy that attracts more jobs to Kentucky. And coal is what allows so many of them do all that," he said.
The congressional resolutions follow court challenges filed Friday by industry groups and states dependent on fossil fuels. The challenges from all but two of the 25 states were filed by Republicans. They deride the plan as an "unlawful power grab by Washington bureaucrats" that will kill coal mining jobs and drive up electricity costs.
The Obama administration and environmental groups counter that the rules are needed to cut carbon emissions while curbing the worst impacts of climate change and sea-level rise. They also say the plan will spur new clean-energy jobs.
The new rules require states to cut carbon emissions by 32 percent by 2030, based on emissions in 2005. Each state has a customized target and is responsible for drawing up an effective plan to meet its goal.
The EPA says it has authority to enact the plan under the Clean Air Act.

Coral Damage From BP Gulf Oil Spill Worse Than Previously Thought. Gulf coral damage from the massive BP oil spill is more extensive than previously thought, according to a new study that revealed sick and dying corals in the rich, deep-water <a href="https://www.bing.com/search?q=enviorment&amp;cvid=319258dbcb644718b586066e7c29e4d0&amp;FORM=ANAB01&amp;PC=HCTS">environment</a> off the coasts of Alabama and Mississippi known as the Pinnacles.
Using remotely operated submarines, researchers explored the Pinnacle Reef in September 2011 and found more than 400 coral colonies were injured. <a href="http://www.earth.com/news/the-great-barrier-reef-has-lost-half-its-corals-in-two-decades/">Corals</a> - such as sea whips, sea fans and black corals - were covered in a scum of dead tissues and oily residue. Some showed severe damage, such as bare skeletons and missing branches.Coral Damage From BP Gulf Oil Spill Worse Than Previously Thought
These colonies are found about 35 miles to 68 miles to the north of BP PLC's blown-out well, which spewed more than 130 million gallons of oil into the Gulf of Mexico in 2010. Previous discoveries of coral damage were found south of the BP well and in much deeper water. The coral in the Pinnacles live about 200 feet under the water surface.
The Pinnacles is a rocky outcropping on the Continental Shelf about 70 miles off the coasts of Mississippi and Alabama.
The study was conducted by a team of Florida State University researchers and federal scientists with the National Oceanic and Atmospheric Administration. It was also done as part of the work to assess damage from the spill, the so-called natural resources damage assessment. The study is set to be published in Deep-Sea Research, an oceanography journal.
The paper said the damaged coral showed signs of injury from an "acute, isolated event rather than ongoing natural processes." It based this conclusion on previous explorations that looked at the corals between 1997 and 1999, which found the corals were mostly healthy.
"We saw many injured colonies," said Ian MacDonald, an oceanographer at Florida State University. He is one of the authors of the study.
He believes a much larger area of the Pinnacles most likely suffered similar damage.
"The area we have looked at so far is only the tip of the iceberg," he said.
The researchers believe oil floating over the Pinnacles was sprayed with chemical dispersants, which led to oil sinking and contaminating the reef. The paper also says a tropical storm that passed over the area during summer 2010 churned up the sea and caused oil to reach the corals.
"It is a new region and a new ecosystem showing impact," said Erik Cordes, a deep-sea marine scientist familiar with the Pinnacles Reef study. He's been involved with teams looking at coral damage closer to the site of the BP blowout.
"We'll have to monitor it over time," Cordes said.
Even though more than five years have passed since the spill, scientists are still locked in studies to figure out where the oil went and what effects it had on the Gulf ecosystem.
MacDonald said one way to protect the reef from further damage would be to designate it as a protected marine sanctuary.

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.
