Viermal mehr Hitzerekorde als ohne Klimawandel Eigentlich gilt: Je länger die Messreihen, desto seltener neue Rekorde. Doch das Gegenteil ist der Fall – wie wir in unserem Reviewartikel in Nature Reviews Earth & Environment zeigen. Blog: www.carbonbrief.org/guest-post-h... Paper: rdcu.be/et273

The @riskkan.bsky.social team at the @asranetwork.org symposium on systemic risk in Les Fontaines! @janasillmann.bsky.social & Pia-Johanna Schweizer. Pia & I will be Co-Leads for the new working group on systemic risk, catastrophic risk& polycrisis, & Jana co-leads the WG on climate risk modelling.

Thanks @futureearth.bsky.social for this very nice article on our first symposium at @iiasa.ac.at! futureearth.org/2025/06/24/r...

Jetzt gibt es also einen umfassenden Zweiten Österreichischen Sachstandsbericht zum Klimawandel... Aber wie können du & ich diesen Bericht zur Kommunikation nutzen? #klimaaktiv hat da eine Übersicht zusammengestellt 🎉 #WissenSchafftKlimaschutz #AAR2 @ccca.ac.at 🔗 www.klimaaktiv.at/klimabildung...

Excited to share our new Nature Geoscience paper on how persistent Rossby waves patterns are triggering simultaneous hot-dry extremes across western Europe, Asia, and the U.S., severely reducing vegetation productivity and carbon uptake. www.nature.com/articles/s41...

On my way to the Stormtracks Workshop ‘25 in Rosendal, Norway. Excited to present our recent results on extreme heatwave drivers and their representation in models. Thanks to T. Spengler and the organizing committee for the invite. stormtracks2025.w.uib.no @iiasa.ac.at @lamont.columbia.edu

Congrats @drchriswhite.bsky.social and many thanks for leading this effort. Excited to be part of this COST-Action and support through @iiasa.ac.at theme on Extreme Weather and Climate Dynamics and several @riskkan.bsky.social Working groups.

May 2025 saw 4% of the Earth's surface setting local record high monthly averages (5% of ocean & 1% of land). May 2025 was also notable for an area in India that had near record low temperatures. So rare to see meaningful areas of blue on these maps anymore. berkeleyearth.org/may-2025-tem...

Climate.gov, a major US government website supporting public education on climate science, will likely shut down after almost all of its staff were fired. What would be worse is if the website were co-opted to publish climate denial content.

Embarrassing.

The Columbia Spectator notes that Columbia and Cornell are the only Ivies that didn't sign on to a new amicus brief defending Harvard against the Trump administration. (Other signatories include Tufts, MIT, JHU, Rice, Rutgers, Caltech, Colorado State, Oregon, Oregon State, Maryland College Park)

Another demonstration of the fact that there is no point in bending to Trump, not just morally, but strategically. Columbia gave in & he just hits them harder... MAGA's goal is to destroy the universities (& newspapers & law firms etc etc etc) and the only logical approach is to unite and fight back

Our study just out in Nature: the extreme North Atlantic heat in summer 2023 was mainly due to weak winds causing shallow mixed layers, which heat up more quickly. Global warming is causing a trend toward shallow mixed layers, making such extremes more likely. 🌊 www.nature.com/articles/s41...

Last day at the GISS building (Wed. May 28th). 🥲

Seeing Blatten buried again and again, from every angle... Properly staggering! 😮😱

IIASA researcher @kornhuber.bsky.social was recently featured in the Climate & Water Series of the @uarizona.bsky.social where he spoke about the physical processes and statistics of high impact climate extremes. 📹 Watch the full lecture: www.youtube.com/watch?v=YIzl...

It's outrageous that NASA GISS, one of the best earth & space science labs in the world, is being kicked out of its Columbia home. The outstanding scientists who work there can't say that publicly, but I can. And so can you --- call your reps, esp. (but not only) if you live in NYC or NY state.

“The lived experience of a scientist right now is terrifying” My colleague Warren Cornwall spoke to @gregggonsalves.bsky.social, @rebekahtromble.bsky.social, @katestarbird.bsky.social and others about “the fear and self-censorship coursing through the nation’s scientific establishment today”. 🧪

📻 IIASA researcher Kai Kornhuber recently discussed his latest study on heatwaves in an interview with CBC/Radio-Canada. 📝 In his study, he used climate model simulations to identify regional hotspots that are experiencing unexpected extreme heat. Read more here 👉 www.cbc.ca/radio/quirks...

Scoop from @byscottdance.com: As the National Weather Service scrambles to fill vacancies, staffing at four local forecast offices is so critical that they are no longer operating 24-7. More offices are expected to follow soon. www.washingtonpost.com/weather/2025...
