Episode 2: Highest Possible Ambition under Overshoot with Joeri Rogelj

In the lead up to the Overshoot Conference @iiasa.ac.at Sep 30-Oct 2, the organizers had a fantastic nerdy idea to get the leading experts in their fields share their perspectives on the key themes. Highly recommend for your daily commute, background to cooking etc.: open.spotify.com/show/5MpXqh1...

⚡ ⚖️ 🌐 upcoming #𝐂𝐥𝐢𝐦𝐚𝐭𝐞𝐋𝐢𝐭𝐢𝐠𝐚𝐭𝐢𝐨𝐧: Asmania v. Holcim
Crucial hearing upcoming in Switzerland, this could set a precedent for holding climate polluters accountable.
📅 Wed, 3 Sept 2025 – starting at 8:30 am CEST
📍 Cantonal Parliament of Zug🇨🇭
👇 A brief thread🧵

🔥 Just published! 🔥
Our new manuscript on global #wildfires look beyond burned areas and ask:
What drives the #economic damages of wildfires — now & in the future?
We find that socioeconomic vulnerability, not just #climate, is key.

*** Faktencheck***
In der Generaldebatte im Bundestag sprach Bundeskanzler Friedrich #Merz auch zum Klimaschutz. Er sagte:
"Selbst wenn wir alle morgen klimaneutral wären, würde keine einzige Naturkatastrophe weniger geschehen". Ein Faktencheck.

Causal pathway from AMOC to Southern Amazon rainforest indicates stabilising interaction between two climate tipping elements - IOPscience Causal pathway from AMOC to Southern Amazon rainforest indicates stabilising interaction between two climate tipping elements, Högner, Annika, Di Capua, Giorgia, Donges, Jonathan F, Donner, Reik V, Feulner, Georg, Wunderling, Nico

New study out, in which we detect a causal link in reanalysis+observational data from an AMOC SST index to the Southern Amazon rainforest: dry season precipitation increases when the AMOC weakens.

🌎 New research led by IIASA researcher @hoegner.bsky.social shows a link between two major climate tipping elements: the Southern Amazon rainforest and the Atlantic Meridional Overturning Circulation (AMOC).

New paper on the risks of forest ecosystem impacts under emissions pathways designed to meet the Paris Agreement temperature goals is out today in Nature Climate Change! 🌳

congrats @sarahschoengart.bsky.social & team !!

💰🌍 Research by Sarah Schöngart et al. shows the wealthiest 10% caused TWO-THIRDS of global warming since 1990. The top 1% have an even bigger impact on extreme weather like #heatwaves and #droughts, hitting vulnerable regions hardest.

Excellent thread on our new paper in Nature Climate Change on what a year above 1.5°C means for the Paris Agreements lower temperature target

Have we already breached the 1.5°C global warming target? Although the climate goals set by the Paris Agreement are based on the long-term average temperature, one year of high temperatures might be a sign that the 1.5°C threshold has already been reached

Great coverage of our recent study on 2024 warming and the 1.5°C limit by @tinymaddie.bsky.social

In Nature Climate Change, we show that a year above 1.5 °C signals that Earth is most probably within the 20-year period that will reach the Paris Agreement limit. @natclimchange.bsky.social
