Is climate change to blame for extreme weather events? Attribution science says yes, for some – here's how it works

A new attribution study finds human-caused climate change made Europe’s July floods more likely. What about Tennessee’s flooding? An atmospheric scientist explains how scientists make the connection.

The water cycle is intensifying as the climate warms, IPCC report warns – that means more intense storms and flooding

Water-related hazards are exceptionally destructive, and the impact of climate change on extreme water-related events is increasingly evident, a lead author of the new report warns.

Extreme heat waves in a warming world don't just break records -- they shatter them

Not every extreme weather event is caused by climate change, but heat waves that were once ridiculously improbable are showing up more often. Just ask Portland.
