NEW: GLOBAL RENEWABLES OVERTAKES COAL How the heck did that happen so quickly?!...🧵

Carbon offsetting suffers from deep-seated systemic problems that incremental change will not solve says review paper from Oxford Uni “We have assessed 25 years of evidence and almost everything up until this point has failed” www.theguardian.com/environment/...

Exciting detective work 🤩

🚨 New @oceaniceeu.bsky.social preprint🚨 why has Antarctica stopped (net) losing mass, in spite of increased discharge? Declining sea ice is part of the answer but increasingly heavy and frequent atmospheric rivers are most important factor. Lots of important subtleties: arxiv.org/abs/2510.03590

Congratulations Beatriz, Tim, Paul and team on this important new study! @gsiexeter.bsky.social www.science.org/doi/10.1126/...

We need more of this kind of optimism and hope. My boy in front of a new mural in Exeter.

NEW DATA | China's exports of clean technologies exceeded 20 billion USD for the first time in August📈 We just published a new @ember-energy.org data tool to track exports of EVs, batteries, gridtech etc. on top of our existing tracking of solar exports. 🧵

Forest clearing in South-east Asia [is associated with] more heat-related deaths than in other tropical places 🌳🌡️ 🔗https://str.sg/KXHH

🚨🌊 New highlight paper out today in Earth System Dynamics! We find an observational constraint implying more future global ocean heat uptake, cloud feedback, and warming than the CMIP6 mean. This contrasts with previous estimates based on past warming trends. 🔗 esd.copernicus.org/articles/16/...

We finally have a new paper out looking at how summary statistics from the AR6 scenario database are highly dependent on the sampling of the database. High profile statistics are often more representative of the model fingerprint, not the physics. www.nature.com/articles/s41... 1/

Now we have something nice and intuitive to better explain air quality, pollution, or dimming and brightening to the wider public. Awesome work! #SciComm airqualitystripes.info/stripes/?con...

#StormAmy probably being named very soon as models are in better agreement this morning. It could be a record-breaker in terms of low pressure for the time of year as well. W + N Scotland in particular is likely to see some intense winds with this one.

Are you interested in seasonal forecasts and how they have advanced over the past two decades? Chris O’Reilly (Univ. of Reading) led a new paper on exactly this: rmets.onlinelibrary.wiley.com/doi/10.1002/...

Yesterday we celebrated the PhD defense of @xinyu66.bsky.social at the Universität Innsbruck 🎓🎉 It was such a pleasure to watch Xin discuss with the evaluators Nadine Ruehr and Georg Wohlfahrt, showing his passion, curiosity and in-depth knowledge on the topic. Congrats Dr. Yu!!!

'Amplified agricultural impacts from more frequent and intense sequential heat events' new paper out led by C. Steinmann & @raedhamed.bsky.social highlighting increased complex risks in a warming climate. iopscience.iop.org/article/10.1... @iiasa.ac.at @climate.columbia.edu @riskkan.bsky.social

I like this one, although it doesn't show temperature outcomes www.carbonbrief.org/analysis-sol...

New paper alert 🚨 🌊 The Southern Ocean and the Arctic are freshening. In our new paper we link, for the first time, such freshening to sea ice decline through salinity and stable oxygen isotopes observations and machine learning techniques. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

A shift in the NAO phase is linked to a slowing Arctic sea ice decline since 2012. Except for the questionable causal association with AMO (which in my view is atmospherically driven, i.e. NAO projects onto AMO), this study does help to explain what's going on up north lately. #ArcticClimateChange

🍩 What if climate looked like a donut? 🌍 Here’s a bunch of cities turned into a sweet dataviz experiment. 🟡 → comfy zone 🔴 → hot 🔵 → cold Why a donut? Let me explain 👇

"After nearly 40 years, the Arctic Research Consortium of the United States, or ARCUS, will close September 30." "The Arctic Research Consortium of the United States funded programs that aided Indigenous communities and tracked melting sea ice, among dozens of initiatives."

Last week the German Meteorological Society warned that "the 3-degree limit could be exceeded as early as 2050". While not possible to fully rule out, the assessed warming scenarios we published in the IPCC AR6 report find this to be extremely unlikely.

There's a really nice new study using phone data from Americans who relocated from one city to another to look at the effect of walkable environments on physical activity. E.g., people move TO New York and walk more, they move FROM New York and walk less www.nature.com/articles/s41...

Estimation of 62,775 heat-related deaths in 2024 in Europe www.nature.com/articles/s41...

Great to see coverage of our first full @wasitusie.bsky.social study on RTE (and elsewhere). Kudos @clairebergin.bsky.social and Lionel swan as well as met Éireann colleagues and thanks as ever to @wwattribution.bsky.social for the hugely valuable collaboration www.rte.ie/news/ireland...

The people I work with are not stupid people and our climate predictions of 30 years ago of global warming have proved to be accurate. Just saying. www.bbc.co.uk/news/live/cp...

A study in Nature Climate Change shows that the ocean carbon sink unexpectedly declined in 2023 despite record-high sea surface temperatures (SSTs), primarily due to SST-driven outgassing of CO2 in the subtropics. 🌊 🧪

'Aren't heat pumps hopeless in the cold?' That's one of three myths busted in the excellent book 'Clearing the Air' @hannahritchie.bsky.social which tackles 50 questions. She clearly shows they perform well in cold weather, citing our Joule paper on heat pump performance during cold weather. 👇

Crossing 2°C is 97% certain (UNEP, 2024) IPCC SR1.5 (2018): “Coral reefs … projected to decline by 70–90% at 1.5°C (high confidence), with larger losses (>99%) at 2°C.” Perry et al. 2025: “If warming exceeds 2°C, nearly all reefs (≥99%) will be eroding by 2100. www.nature.com/artic...

These are the exact expected consequences when the total daily precipitation amount on the earth increases simultaneously as it is dstributed over a smaller fraction of its surface area doi.org/10.1038/s416...

A new study led by @clairbarnes.bsky.social shows that human-caused global warming tripled heat wave deaths in European cities this summer to 24,400. These 16,500 people would still be alive if we weren't burning fossil fuels like there's no tomorrow.

Monthly update of the monthly climate dashboard We now have most global temperature datasets updated to August, but numerous other updates too. www.jkclimate.fr/MonthlyDashb...

🚨 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. Out TODAY in Nature Climate Change: the first systematic look at the science of "health impact attribution" 🔓 www.nature.com/articles/s41...

The summer is over - and for about 16,600 people across 854 European cities that doesn't mean autumn comes, but death. People who would still be alive if it wasn't for our burning of fossil fuels. - New study with @lshtm.bsky.social www.imperial.ac.uk/grantham/pub...

Extreme weather is expected to cost $38 TRILLION by 2050 - a third of global GDP today Another study points - for a 2C rise - to a 25% collapse in global GDP and 2 BILLION dead by this date Welcome to the future on Hothouse Earth www.theguardian.com/world/2025/s...

Since one year, the Research Training Group "Economics of connected natural commons" studies the challenges of sustainably using ecosystems and the climate system as commons. We just come back from the first retreat between the 14 PhD candidates, advisers, and excellent invited external speakers.

My reading this morning! @bloomsburybooksuk.bsky.social @susannahfisher.bsky.social

"the US is on track to reduce GHG emissions by 26-41% in 2040 relative to 2005 levels. On the way to 2040, we estimate GHG emissions levels will decline 26-35% in 2035, a meaningful shift from our 2024 report, which showed a steeper decline of 38-56% by that point" - Rhodium group outlook

Der #Klimawandel bringt eine Intensivierung von #Starkregenereignissen mit sich. Der #DWD analysiert dies regelmäßig, um Veränderungen in Deutschland zu dokumentieren. Der aktuelle Sachstand mit neuen Analysen ist nun als Bericht verfügbar: 👉 t1p.de/kmbnn Auch Thema beim #extremwetterkongress 2025!

In der Nacht 10. / 11.09.25 kam es zu Starkniederschlägen mit einzelnen 🌩️ im Nordosten Deutschlands. In MV im LK Vorpommern-Greifswald sowie in BB im LK Uckermark bis >70mm in 9h, in der Stadt Cottbus (BB) und im LK Spree-Neisse (BB) mit jeweils >50mm in 6h. #Radarwerte, #Wiederkehrzeiten >100 Jahre

🚨📈 Over the last 6 months a series of papers has advanced our understanding of the culpability of fossil fuel firms for climate change impacts. In April, @jsmankin.bsky.social and I showed that economic damages from rising extreme heat can be linked to companies like Exxon and Chevron. rdcu.be/ei0T5

Samstag in Berlin - die Lange Nacht des Klimas! Insg. ein hochkarätiges Programm. Freue mich auf das Gespräch mit euch! www.langenachtdesklimas.de#unsere-theme...

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...
