Climate crisis-driven heat ‘sucking soils dry’ as extreme drought hits Europe
Analysis shows how heatwaves are making atmosphere thirstier, damaging water supplies, food production and power generation
Extreme heat supercharged by the climate crisis is sucking Europe dry in summer and intensifying the drought hitting the continent, a scientific analysis has found.
Record-breaking heatwaves meant the hot atmosphere strongly evaporated water from rivers, lakes, soils and plants – conditions made 80 times more likely by global heating in western Europe and 40 times more likely in eastern Europe, the study showed. The level of soil dryness in the west was made five times more likely by the pollution from fossil fuels in the west, and 11 times more likely in the east.
Droughts have usually been linked to low rainfall, but western Europe’s most recent winter was a wet one. The scientists said the climate crisis was redefining drought in Europe, with high temperatures the key factor this summer. Today’s drought in western Europe is classified as “extreme” but would have been “moderate” in the world before the climate crisis, according to the analysis.

Deadly wildfires have raged through Spain and France and farmers have been hit hard, facing some of the driest soils on record. About 9m tonnes of grain are expected to be lost across Europe, with the worst maize harvest in 50 years expected in France, and Romanian farmers losing over a million hectares of crops.
Rivers are running low across Europe, cutting the generation of clean hydropower and restricting cargo ships. The Rhine at Lobith in the Netherlands is now lower than the minimum level seen in the hot summer of 1976. The scientists warned that this disruption could push up the price of food and energy, hitting low-income households hardest.
