Are the European floods linked to the climate crisis?

Almost certainly. Scientists have long predicted climate disruption will lead to more extreme weather, such as heatwaves, droughts and floods. Human emissions from engine exhaust fumes, forest burning and other activities are heating the planet. As the atmosphere gets warmer it holds more moisture which brings more rain. All the places that recently experienced flooding – Germany, Belgium, the Netherlands, London, Edinburgh, Tokyo and elsewhere – might have had heavy summer rain even without the climate crisis, but the deluges were unlikely to have been as intense.

There has not yet been an attribution study for the latest floods in Europe because the analysis takes several days.

Investigating how climate affects intense rainstorms across Europe, climate experts have shown there will be a significant future increase in the occurrence of slow-moving intense rainstorms.

The scientists estimate that these slow-moving storms may be 14 times more frequent across land by the end of the century. It is these slow-moving storms that have the potential for very high precipitation accumulations, with devastating impacts, as we saw in Germany and Belgium.

Professor Lizzie Kendon, Science Fellow at the Met Office and Professor at Bristol University, said:

“This study shows that in addition to the intensification of rainfall with global warming, we can also expect a big increase in slow-moving storms which have the potential for high rainfall accumulations. This is very relevant to the recent flooding seen in Germany and Belgium, which highlights the devastating impacts of slow-moving storms.

“Our finding that slow-moving intense rainstorms could be 14 times more frequent by the end of the century under the high emissions RCP8.5 scenario, shows the serious impacts that we may expect across Europe if we do not curb our emissions of greenhouse gases.”

The study findings are relevant to climate mitigation and adaptation policy in Europe, with specific implications for future flooding impacts, the design of infrastructure systems, and the management of water resources.

Currently, almost stationary intense rainstorms are uncommon in Europe and happen rarely over parts of the Mediterranean Sea. Accurate predictions of future changes in intense rainfall events are key to putting effective adaptation and mitigation plans in place to limit the adverse impacts of climate change.
