Beach holidays in the climate crisis, France. As an old viral quote said: “Climate change will manifest as a series of disasters viewed through phones with footage that gets closer and closer to where you live until you’re the one filming it.”

Yesterday afternoon 14:09 in Lacanau Océan in France. A pale red sun through the smoke tinged everything in Mars style orange. Welcome in the climate emergency! Despite all denial of the fossil fuel lobby, it’s scientific fact: CO2 emissions heat up Earth & make fires worse. 🔥🔥🔥

Holiday in the climate emergency. No that’s not AI or edited, just a snapshot I just took with my phone on Lacanau beach in France. What future will this boy grow up in? It is in our hands, but time is running out.

Important new study out at Nature Climate Action showing that individual climate actions do not stop people from participating in collective climate action. Instead, they were associated with greater collective engagement and somewhat stronger policy support. www.nature.com/articles/s44...

Fires in France have now burned over 91,000 acres, by far the most of any year since the satellite record started in 2006. Current area burned is about 34x larger than this date in a typical (median) year:

Bundibugyo ebolavirus outbreak in the DRC and Uganda has been declared a PHEIC by the WHO. The highest alert lever it has. This requires swift a and multinational response. Estimated death count is already 80! No vaccine, no rapid diagnostic tests. www.science.org/content/arti...

Der Modal Split für die stadt @wien.gv.at 2025 ist endlich da, und jetzt ist auch klar, wieso die Veröffentlichung so lange gedauert hat. Man versuchte wohl fieberhaft, die schlechten Zahlen (Ziel verpasst, Fußverkehr & Öffis sinken, MIV steigt) schönzureden. Ein 🧵 1/

Guardian-Umfrage aus 2024 unter 380 führenden Klimaforschern: Das Ergebnis ist erschütternd. 🌍 77% der Befragten erwarten eine Erwärmung von mindestens 2,5°C. 🌊 Folgen: Hungersnöte, Massenmigration, Konflikte, Städte unter dem Meeresspiegel. 😔 Viele von ihnen leiden unter Depressionen.

Spiralling global temperatures (1850-2026) It is exactly 10 years since I first put this animated graphic of changes in global temperature online. #ClimateSpiral It instantly went viral. People watched it over and over again. It still offers the power to shock a decade on.

Der Mathematiker Rudolf Taschner hätte eine Auszeichnung von der Universität Wien bekommen sollen, die wird ihm nun verwehrt. Die Diskussion darüber reißt nicht ab. Ich versuche hier eine kleine Einordnung aus meiner Sicht. (Thread)

„Brüsseler Abgeordnete & die Kommission wüssten genau,dass viele Chemikalien 🇩🇪 Konzerne – in #Plastik Produkten, Lasuren, Hautcremes, Putzmitteln & Weichmachern –der Gesundheit schaden. „Doch das nehmen alle Verantwortlichen in Kauf, um Deutschland & die EU als führenden Chemiestandort zu sichern.“

Anfang des Monats berichtete CORRECTIV, dass tausende unbekannte Stoffe aus der Industrie den #Rhein und das #Grundwasser belasten. Aber warum darf die #Industrie sie ungehindert einleiten? Jetzt enthüllt ein Topmanager eines Großkonzerns, wie die Industrie Politiker steuert.

“The climate scientists we surveyed were unambiguous: current economic models can’t capture what matters most – the cascading failures and compounding shocks that define climate risk in a warmer world – and could undermine the very foundations of economic growth.” Should be the top story everyday.

Gestern hat die 🇺🇸 Regierung das „Endangerment Finding“ zurückgenommen. Aber auch in Österreich 🇦🇹 findet eine schleichende Aushöhlung der Klimapolitik und der Klimaforschung statt - durch Verzögerungen, Budgetkürzungen, Prioritätenverschiebungen und politisches Wegsehen. #WissenSchafftKlimaschutz
