What is causing the floods in Europe?

Scientists believe climate disruption will bring more extreme weather, and humans are making things worse

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.
