Scientists raise alarm as crucial coastal habitats face growing threat: 'The results are in'
Despite their significant impact on keeping the planet healthy, a new report from the World Wide Fund for Nature (WWF) and insurance company Aviva reveals that some salt marshes are suffering because of rising sea levels.
As a part of this research and collaboration, data was presented from Aviva's "carbon flux tower," or solar-powered towers that constantly measure the carbon dioxide exchange occurring between the atmosphere and the salt marshes. The company's findings show that salt marshes are carbon "sinks," or capable of storing more carbon than they produce.
"This high-frequency, real-time data reveals that saltmarshes are significant carbon sinks," the report says, "with the amount absorbed during the spring and summer outweighing what is released during the autumn and winter months."
With sea levels rising — mostly due to extreme weather events, caused in part by human-induced climate change — some of the salt marshes are disappearing.
According to an article by The Independent, "Experts warn that 85% of the U.K.'s saltmarshes … have been lost since the mid 19th century."
Carbon removal, such as via carbon sinks, is crucial to keep our Earth healthy and livable. While carbon is produced naturally, an excess of it is caused in part by human activity, such as by burning dirty fuels, like methane gas.
While natural carbon sinks exist, the effect of large-scale polluting gases is rising temperatures, making it harder for these carbon sinks — including forests and salt marshes — to thrive and do their job.
"The results are in, and mud matters," said Tom Brook, an ocean conservation specialist at the WWF, per the press release. "Saltmarshes are powerful natural allies in the fight against climate change — storing carbon, protecting our coasts, and supporting rich biodiversity."
In turn, the organizations' joint press release is calling for salt marshes to be added to the Greenhouse Gas Inventory to raise awareness and help the U.K. achieve net-zero carbon emissions. This move would be a major step in protecting these ecosystems, as further reporting would help garner funding and raise awareness for salt marshes.
To do your part in protecting these vital carbon sinks, you can support organizations like WWF with climate-centered goals and educate yourself on critical climate issues like those affecting salt marshes.

Scientist raises red flags about concerning phenomenon causing sharks to move closer to shore: 'New coastal environments'
Scientist raises red flags about concerning phenomenon causing sharks to move closer to shore: 'New coastal environments' Sharks and other cartilaginous fish are moving to shorelines in the Sea of Marmara as oxygen amounts fall in deeper waters, Türkiye Today reported. What's happening? Pollution and warmer waters have reduced oxygen in the sea's deeper sections. In parts below 200 meters in the eastern area, oxygen is now at zero, said Hakan Kabasakal, fish advisor at World Wide Fund for Nature-Türkiye. This change pushes sharks and similar fish toward shallow shore areas, where they encounter dangers. These fish need at least 4.5 milligrams of oxygen per liter of seawater to stay alive, but many areas of the Sea of Marmara now have less than 2 milligrams per liter. "Due to continued deoxygenation in deep waters, these fish can't return, but they also can't thrive in their new coastal environments because of overfishing," Kabasakal explained. Why is this marine oxygen drop concerning? When sharks swim to shore, it creates a problem for sea life and people who rely on healthy oceans. Out of 1,266 known cartilaginous fish, one-third could die out this century if nothing changes. These animals are top hunters in seafood chains, and when they vanish, whole food webs can fall apart. The issue is bigger than just sharks. Low oxygen creates "dead zones" where most marine animals can't survive. This harms fishing jobs and food sources for towns near the Sea of Marmara. In a three-year study, scientists observed an initial rise in shore shark numbers, but they then dropped rapidly in 2024. This shows that new areas can't keep these moved fish healthy over time. For humans, losing these sea animals means fewer natural hunters of pests and less mix of life in waters that coastal towns need for food and jobs. What's being done about this marine oxygen drop? Work is growing to help these at-risk fish and boost oxygen in sea waters. Do you worry about air pollution in your town? All the time Often Only sometimes Never Click your choice to see results and speak your mind. WWF-Türkiye built a wildlife tracking app called Gozum Dogada (My Eye on Nature) so people can report shark sightings along Türkiye's almost 9,000 kilometers of shore. "The more data we have, the stronger our conservation efforts become," Kabasakal noted. Scientists also combat misconceptions about sharks that instill fear instead of fostering care. He's looking at old shark attack records from the Mediterranean Sea to show they happen much less than people think. If you live by the sea, help by reporting unusual sea life sightings to local nature groups or by using a wildlife app. This gives important information to scientists tracking these changes.

Plastic Bag Bans And Fees Can Reduce Shoreline Litter, Study Finds
EGYPT, RED SEA - DECEMBER 2007: Overview of plastic pollution during a dive on December 6, 2007, off ... More Egypt, Red Sea. In 2050, there will be more plastic than fish in the oceans if nothing is done, its the WWF (World Wildlife Fund). Plastics pollution has a direct and deadly effect on wildlife. Thousands of seabirds and sea turtles, seals and other marine mammals are killed each year. (Photo by) Plastic bag bans and fees could help reduce the number ending up littering shorelines by at least a quarter, according to a new analysis. The study by researchers at the University of Delaware and Columbia University found that plastic bag policies led to a 25% to 47% decrease in plastic bags as a share of total items collected in shoreline cleanups, compared to areas without policies. It also found a 30 to 37% reduction in presence of entangled animals in areas with plastic bag policies. It used data collected by volunteers with Ocean Conservancy's International Coastal Cleanup annual event, which sees volunteers remove trash from beaches and waterways around the world. The U.S. currently has now no federal plastic bag policy, but there are various policies at the town, county and state level, which include bans, partial bans and charges. The study says some types of policies seemed to be more effective than others in reducing plastic litter. For instance, it said fees appear to reduce litter even more than bans, though more study is needed to understand why. Another finding was that the bag bans and fees were most effective in places where the plastic bag litter problem was more severe to begin with. Report co-author Anna Papp said roughly one-third of Americans are living in an area with some sort of plastic bag policy in place in a statement. Papp added the findings do show that plastic bag policies are broadly effective in limiting litter along shorelines. 'Ours is the first large-scale study to use hundreds of policies and tens of thousands of cleanups to look at their effects,' she said. 'But it is important to keep in mind that this is a relative decrease in affected areas compared to areas without policies.' A previous analysis by Ocean Conservancy showed a 29% reduction in plastic grocery bags found on beaches following an increase in statewide plastic bag bans. It also claimed Americans use 100 billion plastic grocery bags each year and on average, plastic grocery bags are used for only 12 minutes before being thrown away. Ocean Conservancy's manager for ocean plastics research, Dr. Erin Murphy said plastic bags are particularly dangerous for the environment in an interview. Dr. Murphy said sea animals can either become entangled with them or ingest them. She added the ingestion of plastic bags has been linked to death in many species, including marine mammals and sea turtles. 'Plastic bags can look to some sea creatures like prey such as jellyfish, and so they may be consumed preferentially in the environment,' she told me. Dr. Murphy said there have also been previous studies, which highlight how high levels of plastic litter can impact tourism in coastal resorts. She added the study provides good evidence about why 'more comprehensive plastic bag bans or well-developed plastic bag fees' need to be introduced. The Ellen MacArthur Foundation's lead of strategy and thought leadership for the plastics initiative, Sander Defruyt said the new research provides clear evidence that plastic bag bans and fees are effective tools in reducing plastic pollution in an email. Defruyt added plastic bags represent just a fraction of all plastics used globally and tackling the plastic pollution crisis requires a much broader systems change. 'We must change how we design, use, and reuse plastics. We cannot simply recycle or reduce our way out of the plastic pollution crisis,' he said. 'Our current wasteful linear plastics economy is broken," added Defruyt. "In this system, fossil resources are extracted from the ground, made into packaging or products, and most often discarded after a very short, single use to end up in landfills, incinerators, or worse, into the environment. 'To fundamentally transform today's linear economy into a circular economy will require a combination of ambitious industry action and policy measures, working in tandem to provide the systems change required," said Defruyt.

Aussie woman's remarkable discovery inside tree hollow
In a world-first, an endangered greater glider has been discovered using its tail in a way no one thought was possible. The species has undergone a rapid decline over the last 20 years, and researchers are working against the clock to understand more about them. The footage of the male glider was captured after a camera with a live-feed was set up in his den. Previously, it had been thought these massive koala-sized animals had tails that were unable to grip, but the footage challenges this assumption. It shows the doting father named Milo using his tail to carry a bundle of eucalyptus stems inside his tree hollow for his child Brimi to eat. Related: 🔦 50-night search in Aussie forest uncovers worrying greater glider find The live stream was set up by Dr Ana Gracanin, an ecologist at the Australian National University. 'This unique behaviour had never been observed before, it's also some of the first evidence for paternal care in the species. Watching the joey take its first few nibbles was adorable, with little bite marks left as it tasted leaves, one by one,' she said. Speaking later with Yahoo News, Gracinin said the discovery had left her feeling 'ecstatic'. 'I've been watching the livestream from my work desk every single day, and they tend to do a lot of the same things — sleep, groom, stretch, groom. So when I was looking back at the activities and seeing Milo bring in leaves was really exciting,' she said. The project was supported by the World Wide Fund for Nature-Australia (WWF), National Parks Association NSW, Wilderness Australia, and Social Justice Advocates of the Sapphire Coast. And it's enabled people around the world to watch the complex social behaviour of glider family. 🚁 Calls to release documents behind helicopter shooting of koalas 🌳 Controversial $350,000 culling plan for 16 Aussie parks Secret hidden beneath Australia's 'most important' parcel of land Gracinin explained that very little is known about greater glider behaviour, particularly when it comes to how they parent. 'Greater gliders are often thought of as solitary, but we've seen Pip, Milo, and Brimi grooming, snuggling, and even engaging in what looks like play,' she said after the footage was discovered. WWF-Australia conservation scientist Dr Kita Ashman said the footage highlights why it's so important for glider habitat trees to be protected. The footage was taken at a secret location on the state's south coast, close to where the NSW state government-owned Forestry Corporation NSW is continuing to log forests known to be home to the endangered creatures. 'Greater glider trees are being logged by a government-owned hardwood business that has lost nearly $90 million in the last four and a half years. Losing that much money to degrade habitat and hurt our unique wildlife is shocking,' she said. 'The NSW government needs to transition out of native forest logging to save greater gliders and other threatened species.'
