🔔🚨 New Publication Alert! Research has shown that the Antarctic Ice Sheet is a climate tipping element. We found: it’s not one — it’s many. 📄 Paper (open access): www.nature.com/articles/s41... 📢 Press release: www.pik-potsdam.de/en/news/late... Tread below 🧵👇

Uncertainty is not your friend: In a new paper published in One Earth, scientists argue that uncertainties in climate projections mean Earth system components could be at a higher risk than we think of reaching crucial tipping points. 🌊 eos.org/articles/ear...

Just out today: The report “A Nordic Perspective on AMOC Tipping” reviews the current state of science on the risk of Atlantic Meridional Overturning Circulation (#AMOC) shutdown. 🌊 Conclusion: it's "a serious risk which requires a dedicated risk management framework". pub.norden.org/temanord2026...

Presented today. The report “A Nordic Perspective on AMOC Tipping” reviews the current state of science on the impacts of potential Atlantic Meridional Overturning Circulation (AMOC) collapse and provides recommendations for policy actions. pub.norden.org/temanord2026...

Fundamentally flawed economic models mean #climatecrisis could crash global economy, experts warn - Shocks from extreme weather disasters and tipping points are entirely missed by the current models used by governments and financial institutions Story by me www.theguardian.com/environment/...

This is a major win The Netherlands will have to put a climate action plan in place to protect the people of Bonaire, AND make stricter climate targets to contribute a fair share to limiting global heating #ClimateJustice

Please spread this far and wide, as stories don't get much bigger than this. When the government blocks even the intelligence services from telling us we're heading for environmental catastrophe, you know we have a problem. A very big problem. Thank you. www.theguardian.com/commentisfre...

While Australian heatwaves were some of the very first extreme events attributed to climate change, people still underestimate how much worse they got - killing more people than all other natural hazards combined.

Loving the snow! ❄️🤩

Trump just said what it is all about. The sooner the world sheds its addiction to fossil fuels, the better. The alternatives are available, plentiful and cheaper.

📢 New paper on the stability of convection in a conceptual subpolar gyre model 🌊 @koenvanderheijden.bsky.social We find resilience of convection to natural salinity variations under current climate conditions, where periods without convection last longer for a fresher gyre. doi.org/10.5194/esd-...

Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

A recent study by Dutch colleagues shows that a shutdown of the Atlantic overturning circulation #AMOC could bring extreme drought to Europe for centuries. That is a thus far underappreciated risk of climate change. @swinda.bsky.social www.yahoo.com/news/article...

With a group of postdocs and PhDs we oppose the use of the Tulip Fund by @utrechtuniversity.bsky.social. As it is set up the fund does little towards helping scientists in countries where academic freedom is under threat, while reducing the career perspective of young scientists even further.

📢 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.

🔥✊Urgent en ingrijpend, maar noem het liever niet radicaal. Met huidige klimaatbeleid stevenen we af op 2,7C opwarming in 2100, want een ongekende ontwrichting van de samenleving zou betekenen. Dat niet serieus nemen, dát is radicaal! Lees het artikel hier ⤵️ bsky.app/profile/wbgr... 2/3

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...

“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.

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...

VVD partij ideoloog en wetenschappelijk directeur trekt de hele klimaatwetenschap in twijfel. Dan snap ik wel dat je niet met GL-PvdA wil, maar liever met PVV

It was a pleasure giving a seminar at the VU today in the Water & Climate Risk group. I enjoyed the great questions and discussion, given me lots of new ideas :) I discussed subpolar gyre variability mechanisms, links with the AMOC and impacts of an AMOC collapse on European precipitation.
