Of the 50,000 heat deaths in Europe in the summer of 2026, 32,000 were killed by fossil fuels. Meanwhile, $65 billion in windfall profits for five biggest oil and gas companies in second quarter of 2026. www.npr.org/2026/10/23/g...

Mexicans were lucky, hurricane Polo hit a sparsely populated region - but already today the impact of climate change is larger than that of El Niño on hurricanes like this. El Niño will pass, climate change will get worse @wwattribution.bsky.social www.worldweatherattribution.org/effect-of-cl...

After a year of many experiencing the brutal reality of climate change, not least in Nepal, COP31 will happen & could provide an opportunity to bring the urgent need to massively accelerate global action on climate change back in focus- maybe - we'll talk about it: www.imperial.ac.uk/events/21370...

Heute wird der westfälische Friedenspreis an die NATO verliehen. Die Frauen in der Jury hatten viele konstruktive Vorschläge für alternative Preisträger gemacht, konnten sich aus unerfindlichen Gründen aber nicht durchsetzen.

What are known causal factors behind rock-ice avalanche near Nepal–Tibet border? @wwattribution.bsky.social Vulnerable slope, potentially weakened by 2015 earthquake, definitely destabilised by climate change through glacier retreat & permafrost thaw. www.worldweatherattribution.org/rapid-warmin...

🧵CO₂ removal (CDR) is back in the news, but just because the UNEP report says we need CDR, it doesn't mean we'll have CDR. Many challenges will take decades of research and negotiation to solve. Here are some examples: Technological: We currently don't have any durable CDR method that scales.

I think the way to read the UNEP report isn't "we'll miss the 1.5°C target so we need CDR to reach it", but "we'll miss the 1.5°C target, and we need to decarbonize ASAP because wherever we end up is where we will stay for a long time." www.unep.org/resources/li...

Europe’s seas are experiencing heat that would have been virtually impossible in a pre-industrial climate. In the Mediterranean, summer SSTs have intensified by 3°C, far exceeding global warming, destroying marine life & dramatically altering our seas. www.worldweatherattribution.org/climate-chan...

Just in case it wasn't already clear... Burning fossil fuels -> more greenhouse gas pollution -> more warming -> super-charged heatwaves + enhanced drought + super-flammable conditions -> all of this. And it's only going to get worse from now on. We really do need to stop.

I know he has a lot on, but in the midst of a ferocious drought, fires, heat events and severe threats to food production, it would be quite edifying to hear Andy Burnham mention climate breakdown.

Yet another fire season that has been made more severe due to the burning of fossil fuels - displacing communities, killing ecosystems, putting huge strain on health systems & fire fighting capacities. New @wwattribution.bsky.social study on Canada www.worldweatherattribution.org/climate-chan...

Is “pragmatic” the new, “grown up” word? Andy, there’s nothing “pragmatic” about drilling for more oil & gas - to even consider it with the planet literally on fire is total madness. How many times must we say it will do nothing for energy bills or security? It would be an act of utter recklessness

A succession of heatwaves and very dry conditions - both driven by human-induced climate change, fueld the severe wildfires in Spain and France - new @wwattribution.bsky.social study www.worldweatherattribution.org/climate-chan...

ExxonMobil will report second quarter earnings in a few days. Most analysts expect profits for the quarter will more than double compared to last year, from $7 billion to about $16 billion.

250 years of burning fossil fuels fuelled a record shattering humid heatwave in Eastern North America for the 250th anniversary celebrations on 4th of July. Turning any outdoor activities into a dangerous health risk. - @wwattribution.bsky.social www.worldweatherattribution.org/fossil-fuels...

Europe's worst heatwave so far, in terms of heat stress measures and temperatures - brought to you by fossil fuels. New @wwattribution.bsky.social study showing how such deadly heat became possible in only a few decades. www.worldweatherattribution.org/fossil-fuel-...

Is Lliuya v RWE reshaping climate litigation? In our new paper, Petra & I unpack the court’s approach to causation, risk, and nuisance law, examine its limited engagement with physics and IPCC science, and why this matters for future climate claims. shorturl.at/yxJuo

NEW: An estimated 7% of the entire population of the critically-endangered Tapanuli Orangutan were killed in a single weather event, according to research led by Borneo Futures with @frediotto.bsky.social as an author. An estimated 58 Orangutans were killed by landslides during Cyclone Senyar (1/4)

Worried about El niño? Conflict and climate change are much bigger drivers of risk, on extreme heat across Asia. During the last El Niño climate change was by far the largest driver of extreme heat, while conflict in West Asia makes people much more vulnerable & exposed. doi.org/10.1016/j.wa...

Every year now, the pre-monsoon heat (the hottest time of year in South Asia with temperatures well over 40°C) starts earlier & lasts longer - due to human-induced climate change - exposing 1billion people to deadly heat. @wwattribution.bsky.social www.worldweatherattribution.org/climate-chan...

NEW: Players and fans face increased heat danger at the 2026 FIFA World Cup, since USA '94. Our results show that from Miami to Kansas City, climate change is increasing the risk of playing the World Cup in much of the northern hemisphere during summer. (1/2)

Hot, sweaty, exciting - and increasingly deadly. Climate change will be an unwelcome but very present player in the upcoming FIFA World Cup in North America - especially in the fan zones. New @wwattribution.bsky.social study. www.worldweatherattribution.org/climate-chan...

A heat dome in north America is producing record-shattering March temperatures, made even more deadly by human-caused warming. A super-rapid study from @wwattribution.bsky.social shows the risk of temperatures as high as these is now four times what it was just a decade ago 😱

March in Western North America is deadly hot, completely above temperatures that would have been possible without climate change from burning oil, coal and gas. New record shatteringly rapid @wwattribution.bsky.social study www.worldweatherattribution.org/record-shatt...

In a rapidly warming world, landslides in high-risk areas are happening sooner rather than later. Making it paramount to reduce exposure & stop the rapid warming. New @wwattribution.bsky.social study on Juiz de Fora landslides www.worldweatherattribution.org/unplanned-ur...

Yes! Go and work with us, @joerirogelj.bsky.social & me and the whole @wwattribution.bsky.social team. You don't even have to be young, you can be old and do intersting climate related reserach!

The Mediterranean is a hotspot of climate change, not only due to more heat, droughts and wildfires, but increasingly severe rainstorms led to catastrophic flooding this winter, highlighting again the urgent need to transition away from fossil fuels. www.worldweatherattribution.org/increasingly...

Patagonian wildfires show how denying climate change & pushing environmental destruction make the reality of climate change much worse. Threatening the destruction of trees that have been alive when the bronze age collapsed. @wwattribution.bsky.social www.worldweatherattribution.org/climate-chan...

It was a tough decision, lots of really good submissions. I’m mostly very happy with where we landed. Enjoy! - & tell me if you think I have terrible taste.

This new video from @climateadam.bsky.social is even more brilliant than usual - insightful and hilarious 🧐🤣❤️ www.youtube.com/watch?v=py0X...

Quadruple whammy: High exposure, vulnerability, La Niña and human-induced climate change turned very heavy rainfall into a disastrous deluge around the Limpopo, Umbeluzi, Maputo, Incomati, Save and Buzi rivers. - new @wwattribution.bsky.social study www.worldweatherattribution.org/la-nina-clim...

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. New @wwattribution.bsky.social study. www.worldweatherattribution.org/climate-chan...

Looking back to @wwattribution.bsky.social studies in 2025 showed again, in stark terms, how unfairly the consequences of human-induced climate change are distributed. The world does not have to be like this, we have a lot of agency to make it better. www.worldweatherattribution.org/unequal-evid...

In the world we live in today, that is 1.3C warmer due to our continued burning of fossil fuels, the extreme rainfall leading to disastrous flooding in many parts of Asia is up to 50 to 160% more intense - new @wwattribution.bsky.social study www.worldweatherattribution.org/increasing-h...

Watch, @fisherdanar.bsky.social , @davidho.bsky.social and me talk about corporate capture, cat capture and where we think things climate could be in 5 years. cece.american.edu/copout-episo...

🎙️ Episode 4 of the COPOut Podcast is LIVE! Tune in to hear from @davidho.bsky.social and @frediotto.bsky.social as they discuss what we know and what we still need to understand (as well as what makes them angry with the climate regime). cece.american.edu/copout-episo...

Two years ago, we did a study on a devastating drought in the Fertil Crescent. Due to climate change and water governance disputes the drought is still ongoing. Teheran might be running out of water, if it doesn't start raining soon. Our update: www.worldweatherattribution.org/human-induce...

I might have failed at my assignment from @fisherdanar.bsky.social to say what makes me hopeful about climate, but I think @frediotto.bsky.social and her team's work that would enable us to hold polluters responsible should be a source of hope. Tune in to Episode 4 of the #COPOut Podcast tomorrow!

Shortly before hurricane Melissa hit the Caribbean, capturing global media attention, Mexico suffered from severed flooding, killing more than 78 people and destroying infrastructure; disproportionally affecting indigenous communities. www.worldweatherattribution.org/heavy-rainfa...

Many congratulations to the amazing @frediotto.bsky.social for receiving the Hans Oeschger Medal! This career award from the @egu.eu Climate Division underlines the ground-breaking research Fredi did on many fronts, most notably on near-realtime extreme event attribution @wwattribution.bsky.social

Baby pigeon mystery. My pigeon book is here: www.hachettebookgroup.com/titles/rosem...

I've got a medal! And not just any, but the Hans Oeschger Medal from the EGU, for outstanding contributions to research on climatic changes. www.egu.eu/news/1551/eg...

If we do not seriously move away from burning fossil fuels, hurricanes like Melissa will only become worse. Already today Melissa tested the limits of what preparedness and adaptation can do. These limits are very real for everyone in the Caribbean. www.worldweatherattribution.org/climate-chan...

Vorschieben, Frauen & Mädchen schützen zu wollen, als würde sexualisierte Gewalt vor allem von Migranten ausgehen, ist so hanebüchen wie perfide. Es ist rassistisch und misogyn zugleich - und eine klassische Erzählung von Rechtsextremen, die im Übrigen nicht auf "Schutz", sondern Besitzanspruch fußt

The sharp rise in hot days since the 2015 Paris climate accord, + alarming future risks lead Science in Action this week with @wwattribution.bsky.social's @frediotto.bsky.social.
