📢 New paper on the impacts of AMOC collapse on European hydroclimate. 🌊 We find an AMOC collapse would exacerbate drought conditions across Europe, linked to reduced precipitation. In combination with climate change droughts are expected to become more frequent and severe. doi.org/10.5194/hess...

The ensemble mean of today's IFS subseasonal forecast now predicts the earliest major sudden stratospheric warming in reliable records, beating 28 November 1968. Will this verify? 👀 charts.ecmwf.int/products/ext...

New national climate plans have barely moved the needle on limiting global warming. Yet there is hope. According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

📢 New paper out! 🌊 We discuss how well mechanisms of variability in the subpolar gyre are represented in climate models, finding that models that do this best are also the models in which abrupt shifts are found 😬. It's a technical story, so here's a simple overview 🧵 doi.org/10.5194/esd-...

🪸 Coral reefs are already reaching breaking point - and we're rapidly approaching other critical climate red lines. That's according to the latest tipping points report that came out last week. Watch here: youtu.be/p9S_IKwwyeM

„This is a national security issue!“ says Dame Angela McLean, the UK Government Chief Scientific Adviser, about the collapse risk of the North Atlantic subpolar gyre. Interesting discussion on Forecasting Arctic Tipping Points - Building an Early Warning System for Everyone, at #ArcticCircle.

📢 OUT NOW: Global Tipping Points Report 2025 📢 💡 A new report provides a temperature check on the status of dangerous Earth system #TippingPoints and opportunities in #PositiveTippingPoints across sectors. Read the full report: global-tipping-points.org/resources-gt... #GTPR2025 #COP30

High resolution images from satellite and from eddy-resolving ocean circulation models point to an ongoing decline of the Atlantic overturning circulation, a key ocean current for our climate. Read more about it in my new blog article. 🌊 www.realclimate.org/index.php/ar...

Great interview of climate scientist Mike Mann and virologist Peter Hotez on the war on science by special interest groups. My colleague Mann endured vicious attacks after his pioneering (and solidly confirmed) ‘hockey stick’ curve of #globalwarming. www.pbs.org/newshour/sho...

“Bivalve records are really amazing. They are like the tree rings of the sea. They offer a continuous, annually resolved record of ocean conditions.” New study finds #AMOC destabilization since 1950 "suggesting that the region is moving toward a tipping point."🌊 insideclimatenews.org/news/0310202...

“We are the most intellectual species to walk the planet, but we’re not intelligent. If you’re intelligent you don’t destroy your only home.” Dr. Jane Goodall

“If we continue, however, with the policies that we have out there, we are clearly on a pathway now of 2.7 degrees or 3 degrees where adaptation is simply not doable anymore. This is just what it is. We cannot protect Amsterdam from sea level rise of 3m. This is just not doable,” Thallinger said.

Vandaag staat mijn visie als hypothetische minister van Landbouw, Natuur, en Stikstof in dit prachtige artikel in @volkskrant.nl Dat stuk is natuurlijk erg kort en simpel, daarom hier een 🧵 van mijn hoofdpunten met wat meer onderbouwing! www.volkskrant.nl/kijkverder/v...

🚨 NEW: Climate change is already causing 30,000 deaths per year - a global annual economic loss of $100-350B USD - but the true damage is probably 10x higher.

De natuur stuurt geen factuur.

This is a nice illustration of how waste powers production. The idea of single-use, discardable plastic 'filling up landfills' was magic for producers. This is the same principle behind fossil fuel companies producing energy, and the tech companies that waste it www.jasontreat.com/plastic-1

Interesting new study! They attributed heatwaves🔥 to emissions of individual companies. Companies that emit a lot of CO2 contribute to climate change, making heatwaves more intense. Can this help in pushing them to reduce emissions and hold them accountable for the damage? doi.org/10.1038/s415...

Wow. The US Energy Department has withdrawn its scam climate report and disbanded its „Climate Working Group“ in order to dodge a law suit against the scam. They must have realized that this scam report by a few „climate skeptics“ is indefensible nonsense. subscriber.politicopro.com/article/2025...

Do people trust science? In the Netherlands the answer is yes, trust even increased. However, the mean hides a change in the distribution, with both high trust (8+) and low trust (5-) increasing. Medical science is trusted most at 74%, climate science around 55%. www.rathenau.nl/nl/werking-v...

We’re filling the atmosphere with CO2 like a bathtub with water. Most of it stays for millennia. That is why the cumulative emissions (the total amount, as pictured here) and not yearly emissions determine the amount of #globalwarming.

Here is a reminder that already last year 44 experts directed a powerful warning to policy makers about the risk of #AMOC shutdown. What more can we do to get heard? It’s like the saying that every disaster movie starts with scientists warning and being ignored.

If you think that dramatic spikes in ocean temperatures aren’t much of a concern, it’s time to think again. There is no time to wait. #ActOnClimate #climate #energy #heatwave #ClimateBreakdown

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100. Our paper on that is out today.🧵

What happens in #Antarctica doesn’t stay in Antarctica: Impacts like #SeaLevelRise will be felt around the globe! 🌎🌊 New important paper led by colleagues from Australia just out in @nature.com: ”Emerging evidence of abrupt changes in the Antarctic environment“ www.nature.com/articles/s41...

Very important to do surveys like this! Is anyone aware of anything similar in the Netherlands (or other countries)? Postdocs do a lot of the research work, the academic system relies on them, yet their future is very uncertain. www.nature.com/articles/d41...

About time that we change the way we look at the world map, away from the #mercatorprojection, towards #equalearthprojection. Greenland is not that big, Africa is not that small. We need to stop the misrepresentation of the size of countries #correctthemap. correctthemap.org

And we're off! The 'Introduction to Complex Systems' summer school has started with a great lecture by Ammy Vogtlander: "Uncertainty is the essence of diversity." And it is that diversity we need for resilience. @ccss-uu.bsky.social #utrechtsummerschool #complexity

It is good to see @economist.com highlighting the importance of climate tipping points, and the work being done to understand and prepare for them. It discusses the work being done by UK groups (including the @aria-research.bsky.social project which I am part of) www.economist.com/interactive/...

Contributed a comment and talked through this piece a while back. Great to see it out. Important findings for England mirroring what we see in other countries and raising questions on vulnerability. I really like writing and helping contribute to work like this. #scicomm #scisky #heatwaves

It was a pleasure to have @rahmstorf.bsky.social visit us in Utrecht last week! He gave an insightful talk on the cold blob, followed by great discussions over lunch and coffee, underpinning the need to improve our understanding of the #AMOC, its impacts and how to communicate about it. 🌊
