New paper alert 🚨 🌊

The Southern Ocean and the Arctic are freshening. In our new paper we link, for the first time, such freshening to sea ice decline through salinity and stable oxygen isotopes observations and machine learning techniques.

🧪⚒️ Always exciting when we have a PhD.defence!
On Friday, Wanyee Wong @NORCE and the BCCR will defend her thesis "Sea ice in the Nordic Seas during Dansgaard-Oescher events"🌊 @scienceandtechuib.bsky.social

Key takeaway: Sea level rise isn't just about coastal flooding. It's a global climate disruptor affecting inland regions too.

Both coastal AND inland countries face new threats from rising seas.

Intensification of extreme cold events in East Asia in response to global mean sea-level rise - Nature Communications

This study uses climate model experiments and shows that global mean sea-level rise can reshape atmospheric circulation and intensify winter cold extremes in East Asia, threatening not only coastal but also inland regions.

General sea level has risen by ~0.2 m over the past century and is projected to rise further by 0.38 m (0.77 m) by 2100.

The relationship between the response of extreme cold days and sea-level rise is nonlinear. Significant increases in cold extremes appear once sea level rise exceed ~0.6m. (3/4)

The mechanism: Sea level rise → North Pacific warming → atmospheric Rossby waves → weakened westerlies → more blocking events over Eurasia → Arctic cold air floods into East Asia.

It's a cascade effect linking oceans to atmospheric circulation to extreme weather. (2/4)

Rising sea levels are making extreme winter cold events MORE frequent and intense in East Asia. Yes, you read that right. New paper in Nature Communications reveals a fascinating connection. (1/4) 🧪🌊

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.

Climate models can be a challenge to understand, but a new app from the NorCPM-team is using AI to make complex data understandable.
