If you want to learn more about Storylines of Marine Heatwaves, my #OOSC presentation starts today at 16h30 🌊

To celebrate the kick-off of #UNOC3 and #OOSC in Nice, we share a striking, mesmerising perspective on Mediterranean Marine Heatwaves —and their clear amplification by climate change.

So it begins.

Day 1 (of 2) of traveling to #OOSC & #UNOC3 in Nice by train, all the way from Northern Germany 🚝
Looking forward to meet some of you there!

Climate models offer little clarity on how climate change will affect the Beaufort Gyre, an influential current in the Arctic Ocean. Most predict the current will weaken or even stop, but the timing and impacts of this fate remain uncertain. eos.org/research-spo...

🆕 from PolarRES' @raphaelkoehler.bsky.social & colleagues on the future of the Beaufort Gyre, a major Arctic Ocean current.

By accumulating/releasing freshwater, it shapes ocean properties.

But most CMIP6 models project it will weaken or vanish, disrupting ocean circulation.

Our new study is out:

The Arctic Beaufort Gyre is projected to weaken or vanish in most CMIP6 models under future climate change.

The gyre would thus stop storing freshwater in its centre, with possibly large impacts on the Arctic and beyond.
