The rate of #Antarctic sea ice extent growth has increased over the last few weeks as we approach this year's annual maximum (austral winter). No new records will be set this year, thought current ice concentration remains quite low in several regions. + More at zacklabe.com/antarctic-se...

🌊The Southern Ocean is warming, is productivity changing? New paper by Liniger et al. uses the nitrate sensors on 274 SOCCOM/BGC-Argo floats to compute annual NCP. It has increased significantly over the past two decades. @mbarinews.bsky.social @soccomproject.bsky.social @bgc-argo.bsky.social‬

For six years, we've shared the stories of the polar worlds. Now, our own story is coming to a close. We've written a final message to our incredible community to say thank you and goodbye. Our journey will end on August 31, 2025. Read our full farewell here polarjournal.net/a-farewell-f...

📉 Antarctic sea ice has hit record lows between 2022 and 2025. A new summary on the Antarctic Environments Portal explores the causes, consequences, and signs of a lasting regime shift in the sea ice system. Full article: doi.org/10.48361/KVK...

Arctic glaciers face ‘terminal’ decline as microbes accelerate ice melt

Disregarding the extreme and record-low sea-ice extent in Antarctic the last two years, this year's July extent is exceptionally low, ranking as the 3rd lowest on record. The July extent over the last four years differs significantly from that of the previous four decades. @osi-saf.eumetsat.int

Groundbreaking insights about rivers beneath the West Antarctic Ice Sheet, and their role in Ross Ice Shelf melt, have been uncovered. SWAIS2C Co-Chief Scientist Huw Horgan led the team observing this water entering the ocean cavity at KIS2, on the grounding zone of the WAIS 👉https://bit.ly/44FFniV

The general trend is crazy. Here is Twitter vs Bluesky volumes for the last week. On some days they are equal in volume.

It’s not every day you come eye-to-eye with a sevengill shark. But that’s what happened to PhD candidate Eva Ramey while carrying out research in Fiordland waters. Eva and Dr Alice Rogers, director of the Coastal Ecology Lab at Te Herenga Waka, recently talked to RNZ about their research.

I don't particularly enjoy being a prophet of doom, but at the start of January @brianmchugh.bsky.social asked about my hopes and fears for climate in 2025. My fears about what would happen to sea ice in both the Arctic and Antarctic seem to be coming true. yorkshirebylines.co.uk/news/environ...

Sea ice in the Arctic and around Antarctica cool our climate, drive ocean circulation across the planet, and provide a unique habitat for polar ecosystems. Sea ice amounts have now fallen to their lowest since we started measuring them. This is not good. 🌊🥼❄️🧪 www.bbc.co.uk/news/article...
