By applying a tracking method to both climate models and satellite data, @davyclimate.bsky.social found that sea ice age is a more sensitive indicator of change than ice thickness or volume.

In the Arctic, sea ice has a leading impact on ocean surface dynamics, mainly in the regions that are seasonally ice-covered. Supply et al., examine the seasonal cycle of the ocean surface conditions in the seasonal ice zone 🌊

🌡️ Not all hot nights are equal. We track “tropical nights” when temps never dip below 20 °C—but what if it’s already 20 °C at bedtime? I crunched ERA5 data for 5 European capitals. Let’s talk tropical 10 pm. 👇

The Arctic Ocean acts to stabilize the AMOC

New paper in #ScienceAdvances by researchers from @bjerknes.uib.no and @oxuniearthsci.bsky.social showing how ongoing Atlantification and sea ice loss leads to a strengthening of the Arctic overturning circulation.

Atlantification drives recent strengthening of the Arctic overturning circulation

A less ice-covered Arctic shifts dense water formation northward, strengthening the Arctic Ocean overturning circulation.

Not bad at all! neXtSIM was mostly designed to represent the deformations of pack Arctic sea ice, so we wanted to check which opportunities it could offer in the Antarctic. Our results suggest that neXtSIM does pretty well at capturing the ice response to storms in regions like the Weddell Sea. 2/3
