Ammon News - Human-caused climate change has intensified a drought across Europe, with extreme heat, rather than low rainfall, driving the exceptionally dry conditions, a team of international scientists said on Thursday.

The continent is gripped by a major drought, with countries from France to Romania confronting parched rivers, water restrictions and devastating wildfires after a historic heatwave in June.

A new study found that today's hotter climate has accelerated moisture loss from Europe's soils, lakes and rivers, increasing the likelihood of bone-dry conditions.

Much of Europe received below-average rainfall during spring, but it was climate-driven heat that made the drought "more severe", said Mariam Zachariah, who co-authored the World Weather Attribution group study.

"Overall, our results show that this drought is not primarily a story of low rainfalls but of a warmer atmosphere that is causing more moisture deficits on the land," Zachariah, from Imperial College London, said. "This means that even in regions where the rainfall has changed little or is projected to increase seasonally, drought risk continues to rise."

Scientists said climate change is making destructive events such as droughts, floods and heatwaves more frequent and intense, and that Europe is the world's fastest-warming continent.

For the study, scientists from Europe, the United States and the United Kingdom used weather data and computer models to compare a drought in today's hotter world with a climate that was 1.4C cooler.

They found that extremely dry soils were five times more likely today in western Europe than in a world without climate change, and 11 times more likely in eastern Europe.

The exceptionally high levels of evaporative demand – the atmosphere's potential to draw moisture from soils and plants – observed between April and June in western Europe were about 80 times more likely.

"Because the atmosphere is now thirstier, the same rainfall deficit that might not have caused a drought in the pre-industrial climate can now lead to a more severe event,” said Zachariah.
