Droughts and associated heat waves threaten society and nature, as again demonstrated in this year's drought event in Europe. This study examines the impact of global warming on drought severity in west-central Europe by creating future analogues of present-day droughts. On the one hand, this approach allows the authors to investigate changes in droughts conditional on the present-day atmospheric circulation. On the other hand, the future drought analogues are directly linked to real-world events and their societal impact, which make the results very tangible and therewith useful for climate change communication to policy makers, decision makers as well as the broader public.
Short summary
To examine the impact of global warming on west-central European droughts, we have constructed future analogues of recent summers. Extreme droughts like 2018 further intensify, and the local temperature rise is much larger than in most summers. Years that went hardly noticed in the present-day climate may emerge as very dry and hot in a warmer world. The changes can be directly linked to real-world events, which makes the results very tangible and hence useful for climate change communication.
