World's sea-ice falls to record low The world's frozen oceans keep the planet cool, but they currently have less ice than ever recorded before.

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.

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and April by looking at the decadal average line positions.

Saturday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data)

• about 790,000 km² below the 2010s mean
• about 1,450,000 km² below the 2000s mean
• about 2,040,000 km² below the 1990s mean
• about 2,430,000 km² below the 1980s mean

Dominant inflation of the Arctic Ocean’s Beaufort Gyre in a warming climate - Communications Earth & Environment The Beaufort Gyre, the largest Arctic freshwater reservoir, will accumulate more freshwater, elevate sea level, and intensify its circulation as the climate warms, driven by increased freshwater fluxe...

Our new paper on the inflation of the Arctic Ocean's Beaufort Gyre was published this week.
The gyre inflation in a warming climate implies its increasingly important role for the climate system and marine ecosystem. @natureportfolio.bsky.social @commsearth.bsky.social

Climate change and terrigenous inputs decrease the efficiency of the future Arctic Ocean’s biological carbon pump - Nature Climate Change Changes in the Arctic could impact the oceanic carbon sequestration of the region. Here the authors consider regional biogeochemistry, including coastal erosion and river inputs, to show a 40% reducti...

Massive piece of work by Laurent Oziel and many #AWI colleagues, conducted within the #COMFORT project:

Laurent conducted future 🌊 Arctic Ocean high-resolution simulations that account for climate change AND carbon & nutrient inputs from rivers & coastal erosion.
