Climate scientist, professor of Physics of the Oceans in Potsdam. Opinions my own.

Stefan Rahmstorf is a German oceanographer and climatologist. Since 2000, he has been a Professor of Physics of the Oceans at Potsdam University. He studied physical oceanography at Bangor University and received his Ph.D. in oceanography from Victoria University of Wellington (1990). His work focuses on the role of ocean currents in climate change. He was one of the lead authors of the IPCC Fourth Assessment Report. .. more

How likely is an #AMOC shutdown? Here's our latest study based on 768 runs with 38 standard climate models (the CMIP6 models). Note these do not include any meltwater from Greenland mass loss, so might underestimate the risk a bit. 2/2

Collapse of key Atlantic current could bring extreme drought to Europe for centuries, study finds. @swinda.bsky.social
That's an under-appreciated impact of #AMOC shutdown, of particular concern given the recent results showing much higher likelihood of this. 1/2

You can’t spell my name, you haven’t checked whether I’m an author on the paper (I’m not), and the cost estimate for climate change damages to the global economy had to be revised from 19% to 17% due to faulty data for one country.
Scientists correct errors; that’s the basis of trust in science.

And, of course, every US state except Alaska gets more sun than Germany. Don’t fall for the fossil-fuel propaganda broadcaster Fox News claiming that solar works here because “Germany has lots more sun”. Solar works almost everywhere.

Great podcast explaining to Americans how “balcony solar” took off in Europe, with millions in Germany 🇩🇪 alone now harvesting solar power with these panels that you just take home and plug in, and they pay back their price within a few years.
Today on Volts: I've had more requests to cover this than almost any other topic in the pod's history, so now, at long last, balcony solar! We dig into how "plug-in solar" took off in Europe & how it's making its way to the US, starting in Utah. Backyard DIY types rejoice!
What's the deal with balcony solar?
Cora Stryker joins me to explain how "plug-in" solar took Europe by storm and is finally, via Utah (?), making its way to America.

One of the reasons why an #AMOC shutdown “cannot be considered a low likelihood risk anymore” is this study:

That study lead to ridiculous "an Ice Age cometh" claims in the Murdoch media (NewsCorp). Given their long history of climate science denial, they probably jumped on this opportunity to confuse the public about #GlobalHeating.

Hey Murdoch fake-news media! The study you report on here
1. Predicts nothing but is about the past.
2. Is not about Gulf Stream but #AMOC.
3. An AMOC collapse wouldn’t cause an Ice Age.
Incompetence or intent to confuse?
The study by Ren et al shows AMOC has weakened: www.nature.com/articles/s43...

A sub-field of science looks at whether the Atlantic ocean circulation #AMOC has weakened. Direct measurements suggest yes but only started in 2004. So people look at temperature and salinity data.
A new study finds a robust slowdown fingerprint at 1000–2000 m depth.

Giving in to authoritarianism rather than sticking up for free speech. What has become of the BBC?
I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.

They deleted the line in which I describe Donald Trump as “the most openly corrupt president in American history.” /1

It should be obvious by now that we cannot make the future of human civilisation dependent on whether the fossil fuel vendors vote for ending fossil fuel use.
Rather, it is up to those who buy fossil fuels to end their lethal addiction fast, before it is too late.

When a government speaks responsibly about climate risks. Iceland's climate minister Jóhannsson:
"We believe that confronting climate tipping points and the risks they pose openly is not a sign of 'pessimism' or 'alarmism' but a sign of realism and responsibility."
