The Northern Pacific Ocean is currently smashing temperature records.

And it is reaching these levels far earlier than the current generation of climate models had expected.

A short thread 🧵

Time series of monthly Northern Pacific Ocean sea surface temperature anomalies from 1850 to August 2025 alongside multi-model expectations of the warming in this area (scenario SSP2-4.5).

💪 A superpower of the Southern Ocean is taking up heat and carbon from humans and slowing the rate of global warming, by exchanging heat and carbon between the atmosphere and the deep ocean.

🔄 The freeze-and-melt cycle of sea ice drives this exchange by changing water density and acting as a pump.

With emissions still rising 📈 and the catastrophic consequences 🔥 becoming ever clearer, geoengineering is getting ever more tempting 🧪

But a review has concluded that the main methods proposed to save polar ice 🧊 are not doable or won't work

Geoengineering is not going to save the poles from climate change

A review of the five main methods proposed for cooling down the poles or slowing the loss of ice concludes they are all wildly impractical, wouldn't work, or both

As the giant #Antarctic iceberg #A23a is currently breaking apart, we created a video about its dance in the water in the last year, including spinning in a Taylor column! Even though A23a is not sea ice, the microwave signature is similar and it shows up in our data! Can you spot it in the video?

Have you lived, worked, or journeyed in the polar regions? Do you have a story, memory, or reflection from your time there?

UK Polar Network (UKPN) and APECS Netherlands are creating a collection of voices from the Arctic and Antarctic — and we would love to hear yours!

Hi! I’m ARIEL, an L-band microwave radiometer 📡, and this is my little buddy Sebastian (the pulka 🛷). Together, we traveled across 3 Arctic ice stations ❄️ to uncover the invisible (aka microwave) secrets of ever-changing summer sea ice and its thickness on the @awi.de CONTRASTS #expedition 🧊.

Antarctica is in extreme peril

New research catalogs several “abrupt changes,” like a precipitous loss of sea ice, unfolding in Antarctica with dire implications for us all.

Antarctica is changing at s disturbing rate.

“What happens in Antarctica won’t stay there.

The stakes could not be higher. The choices made now will determine whether we face a future of worsening impacts and irreversible change or one of managed resilience to the changes already locked in.”

Dana Bergstrom @danambergstrom.bsky.social · Aug 20

Antarctica is undergoing abrupt changes which most likely will significantly intensify in the future. Caused by climate change, they span ice sheet, sea ice, ocean & life itself .
These changes are a clarion call to all of us, ‘cause what happens in Antarctica affects us all. 1/

From sea ice to ocean currents, Antarctica is now undergoing abrupt changes – and we’ll all feel them

The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.
