As long expected. It’s climate science 101. The vapor thirst of the atmosphere increases exponentially with temperature. A law of physics known since the early 19th C (Clausius–Clapeyron law). It causes more drought even if rainfall doesn’t decline. https://www.theguardian.com/environment/2026/jul/23/climate-crisis-heat-sucking-soils-dry-extreme-drought-europe-analysis?CMP=Share_iOSApp_Other

And that makes wildfires go out of control.

@rahmstorf@fediscience.org yes, in my garden when temperature goes above 30 celcius I have to water pots a lot more often to avoid plants dying from thirst.

@rahmstorf@fediscience.org What gets soaked up will come down as super saturated air encounters cold air mass. What is sent up will come down and probably in a big fat deluge. Thanks to the blobs of cold air flung off the Arctic now because there’s no jet stream to corral them Very likely the way carbon emissions collapse is when the world‘s manufacturers suffer food disruption. This means Asia Before aught else they must eat. Before anything, they must have water. They won’t and then they will in a torrent

@rahmstorf@fediscience.org Thanks for posting this. “Its (Clausius–Clapeyron relation) relevance to meteorology and climatology is the increase of the water-holding capacity of the atmosphere by about 7% for every 1 °C (1.8 °F) rise in temperature” - https://en.wikipedia.org/wiki/Clausius–Clapeyron_relation #TodayILearned #TIL

@rahmstorf@fediscience.org Das schöne ? deutsche Wort dazu: "Dampfhunger". In den Medien wird immer geschrieben / gesagt: "wärmere Luft "kann" mehr Feuchtigkeit aufnehmen." So als hätte sie eine Wahl... Sie kann nicht nur, sie WILL! Sie tut es.
