In 2016, countries made history by protecting the Ross Sea. Ten years later, no new marine protected areas have been established in the Southern Ocean. As John Kerry writes in Prospect Magazine, it’s time to keep our promise to protect Antarctica. prospectmagazine.co.uk/polit…

Emperor penguins are now officially classified as endangered by the @IUCN. Creating marine protected areas around Antarctica can support penguins—and the entire Southern Ocean ecosystem. #WorldPenguinDay 📸 Ian Parker/Unsplash pewtrsts.org/4mMYbW8

Unfortunately, Australia’s biodiversity is in ongoing decline, threatened by development, invasive species, and more. The new Nature Media Centre is raising awareness of this loss and building public support for conservation. pewtrsts.org/407BVvO 📸Vince Russell/Unsplash

The science is sufficiently clear—deep-sea mining will cause irrevocable damage to ecosystems we're just beginning to understand. We're calling for a moratorium on seabed mining—before any irreversible harm is done. pewtrsts.org/4qHsdMM

Deep-Sea Mining May Harm Thousands of Species—Before They Are Even Discovered

New research by the U.K.’s Natural History Museum, funded by The Pew Charitable Trusts has estimated the number of known and unknown benthic animal species—those that live on or near the seafloor—in...

#BREAKING: New estimates reveal that the North Atlantic Right Whale population has increased – proving their resilience. With just 384 remaining, we can’t let Congress threaten one of the only laws protecting them. Speak up: oceana.ly/4hoMRNt

Antarctica’s krill fishery has been forced to shut early for the first time ever. CCAMLR Members have a chance over the next two weeks to turn the tide by creating the Antarctic Peninsula MPA. Let’s keep Antarctica’s food web, and our climate buffer, intact: asoc.org/ice-archive/antarct…

🌍 New research shows Antarctica is now showing climate change impacts eerily similar to Greenland, with melting ice and accelerating glaciers. Scientists warn this “Greenlandification” could drive global sea levels even higher. ❄️📈 phys.org/news/2025-10-antarc…

Antarctica sees similar climate change effects as Greenland: Study

The planet's warming climate is having effects in Antarctica that increasingly resemble those observed in the Arctic, meaning global sea levels could rise faster than previously predicted, Danish...

East Antarctica faces unprecedented threats: record 38.5°C heat in 2022, 28°C heatwave in 2024. Its ice sheet holds 80% of Earth’s freshwater, enough to raise sea levels by 52m. Fishing for krill & toothfish continues without protections. 📷️ John Weller

👎By 2040, plastic production could increase by 66% and plastic pollution could almost double—leaking into our environment and harming our health. 👍 A strong U.N. treaty could reduce plastic pollution by 7x. #INC5 📸Getty

95 countries are calling for a @UN plastics treaty to reduce plastic production to sustainable levels. As world leaders convene for INC5.2, they must finalise an ambitious global agreement to protect our planet.
A person in green clothing collects plastic waste along a polluted shoreline. The water is murky and surrounded by trash, including plastic bottles and containers. Overlaid text reads: “If the plastics treaty doesn’t take the entire lifecycle of plastic into account, it won’t truly tackle the problem—or protect our health and environment.” — Sarah Baulch, The Pew Charitable Trusts.
