One of the most immediate climate tipping point dangers is an abrupt cooling of the subpolar gyre, with major impacts on 🇪🇺 climate possible in the next decades. 🌊 Great how @swinda.bsky.social Falkena et al. use advanced causal inference methods to tease out the mechanisms! arxiv.org/html/2408.16...

The ocean takes up a quarter of our CO2-emissions. If that share declines as marine ecosystems become increasingly stressed by ocean heating and pollution, we are in trouble. #WorldOceanDay globalcarbonbudget.org

Today is anniversary of D-Day, and as I heard this on the radio I thought of oceanography prof Jack Darbyshire, who taught me wave dynamics in Bangor in 1982/83.

So glad to see that the AGU is fighting back against the Trump administration‘s efforts to dismantle the U.S. scientific enterprise! Caving in to authoritarian threats is not an option. In Germany we know too well where that would end. fromtheprow.agu.org/forward-with...

Great article on how a German court has ruled that private companies can be held liable for their share in causing climate damages. It's the polluter pays principle, and as such should be a no-brainer. But the fossil fuel industry has so far thought to be exempt. theconversation.com/one-lawsuit-...

Out today in Nature, our paper on the drivers of the record 2023 summer heating of the North Atlantic. Temperatures warmed to record levels in just a few months. The impacts on climate & ecosystems were severe. A thread on how this work came about and what we found.👇👇🧵 www.nature.com/articles/s41...

Our study just out in Nature: the extreme North Atlantic heat in summer 2023 was mainly due to weak winds causing shallow mixed layers, which heat up more quickly. Global warming is causing a trend toward shallow mixed layers, making such extremes more likely. 🌊 www.nature.com/articles/s41...

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd. It's not just budgets but research, institutions, expertise, and training the next generation.

That’s not some tragedy that fell upon the world, but a totally predictable (and predicted for well over 3 decades) outcome of fossil fuel use. It must end very quickly to prevent far worse things to come.

The US does not stand for freedom and democracy any more, but is sliding fast into tyranny. Harvard is punished for standing up to this. If you’re in the US and not doing something now, soon you will be unable to do anything. We know this from experience here in Germany.
