Heat 'sucking soils dry' as extreme drought hits Europe

scienceJul 23, 2026351,788

Extreme heatwaves supercharged by the climate crisis are evaporating water from rivers, lakes, soils and plants and driving an “extreme” drought across Europe, a new analysis found. Record heat made rapid atmospheric evaporation 80 times more likely in western Europe and 40 times more likely in eastern Europe, and raised the probability of the observed soil dryness fivefold in the west and elevenfold in the east. The assessment up to the end of June reported major impacts: about 9 million tonnes of grain expected lost across Europe, France facing its worst maize harvest in 50 years, and Romanian farmers losing over a million hectares of crops. Rivers and reservoirs are also depleted, cutting hydropower and restricting shipping, the Rhine at Lobith is lower than its 1976 minimum, and many areas, including most of southern England, are under hosepipe bans. Dr Dominik Schumacher of ETH Zurich said hotter air is “sucking the soils dry,” and Dr Mariam Zachariah of Imperial College warned these evaporative conditions are already occurring at 1.4C of warming and could double in likelihood if warming reaches 2.8C. The researchers and the UN climate chief Simon Stiell warned the drying threatens food and energy supplies and could push up prices, hitting low-income households hardest.

Major climate impacts on crops in North America and Europe. Major shipping disruptions in the Strait of Hormuz and now, potentially, the Red Sea. Transit through the Panama Canal threatened by drought. It's time we started getting serious about #FoodSecurity.

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. www.theguardian.com/environment/...

➡️ Climate change is driving drought in Europe - but not how you might expect. While there isn't a clear signal for climate change impacting the dry weather, extreme heat is sucking more moisture out of the landscape. (1/3)
