Researchers agree that climate change has made torrential downpours more frequent—but the science gets murky when examining how strong the link is between an extreme event and climate change.

"These are roughly one-in-1,000-year events, [and] would be extremely rare in the absence of human-caused warming,” one climate scientist says.

The rapid analysis by World Weather Attribution calculated that climate change might have tripled the death toll from the event.

Europe's latest spell of sizzling heat, which ended last week, caused a threefold rise in heat-related deaths because human-induced climate change boosted the intensity of the heat wave, British scientists said.

We now have the ability to rapidly assess the impact of climate change after extreme weather events – a first of its kind analysis has shown that it nearly tripled the death toll from the most recent
