New research raises the alarm for ecosystems and agriculture. Samples from 2015 to 2018 showed that summer droughts were the most severe Europe has seen in 2,110 years as climate change stokes punishing heat waves. Using data from tree rings in living and dead European oaks going back to the time of the Romans, scientists identified a long-term drying trend that suddenly intensified in 2015 beyond anything seen in two millennia. The researchers said that this cluster of abnormally dry summers was likely caused by human-driven climate warming and changes to the circulation of the jet stream. ‘Climate change does not mean that it will get drier everywhere. Some places may get wetter or colder, but extreme conditions will become more frequent, which could be devastating for agriculture, ecosystems and societies as a whole,’ said lead author Ulf Buntgen, professor of environmental systems analysis of Cambridge University.
