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 https://t.co/7b9qhRs6Kp

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. https://t.co/TjMQGww5is

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. https://t.co/B3N78iGuoF

ICYMI: 60 countries have ratified the landmark #HighSeasTreaty, paving the way for countries to establish a network of high seas marine protected areas and helping governments meet global #30x30 goals.

"Sustaining life on earth is a task that we must undertake urgently and responsibly," urged @GabrielBoric at #UNGA.

Countries can—and must—establish marine protected areas in the Southern Ocean this month at #CCAMLR. #ProtectAntarctica https://t.co/EHHzGAeY2w

#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.

🚨 Our planet needs action - and the Southern Ocean is the place to start.

🎥 Watch our official campaign video and join the call to protect one of the last great wildernesses on Earth.

Together, we can help meet the #30x30 goal and #ProtectAntarctica.

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: https://t.co/jOiu5lZQKX

#SundaySpecies: Throughout their lives, ribbon eels change colors — and genders! 🌈

⚫️🟡 Juvenile are born male in black and yellow.
🟡🔵 As they grow, they turn yellow and blue.
🟡🟡 At maturity, they switch to female and become fully yellow.

More than half of assessed Mediterranean fish stocks are overfished.

When the @FAO General Fisheries Commission for the Mediterranean meets next month, they can agree to help rebuild populations and protect vulnerable habitats. 📸Damir Sagolj/Getty Images https://t.co/qxDAZ024nj

🌍 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. ❄️📈

🌊 The Antarctic Circumpolar Current (ACC) is Earth’s largest ocean current, a cold, powerful ribbon connecting the Atlantic, Pacific, and Indian Oceans. A new study found it flowed 3× faster and shifted 600 km south ~130,000 years ago. https://t.co/6NRu5bYhow

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

“Science-based management and strong oversight could bring valuable fish populations back from the brink of collapse and could offer a brighter future,” says our Rachel Hopkins on reversing this trend. https://t.co/3vmaDSsBRv

"I wish people could understand that the ocean is not just a massive amount of salt water, but rather it's a living system. What we put into the ocean changes the chemistry of not just the ocean, but of the planetary functions as a whole." @SylviaEarle

The Domain 1 MPA would protect 460,000 km² of the Antarctic Peninsula vital for krill, penguins & whales. Sponsored by Argentina & Chile and scientifically grounded in 143 data layers, it includes no-take zones & adaptive protections.

👎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

Plastic is choking our planet—it's time to act! 🌍💥
Join the movement to #BeatPlasticPollution by reducing single-use plastics, reusing what you can, and recycling right. Every action counts for a cleaner, greener future! ♻️ #EcoAction #Sustainability #ClimateAction #ActNow

[Ralf Sonntag @Perrywedel]

very important!!!

[Pew Europe @PewEurope]

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.

Wirtschaftsministerin Reiche möchte offenbar mit einem Gefälligkeitsgutachten den Ausbau der Erneuerbaren abwürgen, anstatt endlich ihre Arbeit zu machen und sich um den Ausbau von Netzen und Speichern zu kümmern. Das dürfen wir ihr nicht durchgehen lassen https://t.co/sw5VyVccbv
