PARIS, France — 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 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 has 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, told reporters. "This means that even in regions where the rainfall has changed little or is projected to
