The extreme heatwave that caused record temperatures last week across Western Europe was made more likely — and severe — by human-induced climate change.

In France and the Netherlands, where temperatures rose above 40 °C, climate change made such a heat spell at least 10 times — and possibly 100 times — more likely to occur than a century or so ago. The findings come from a rapid analysis by scientists with the World Weather Attribution group that combined information from models and observations.

In the United Kingdom and Germany, climate change made last week’s event five to ten times more likely, the group found. And in all locations, observed temperatures were 1.5–3 °C hotter than in a scenario in which the climate was unaltered by human activity.
