The Fingerprints of Global Warming on Extreme Weather

When climate scientists examine whether the warming of the Earth has made extreme weather events such as heatwaves or downpours more likely, they generally do it on a case-by-case basis. But a group led by Stanford climate scientist Noah Diffenbaugh has aimed to develop a more global, comprehensive approach to investigating how climate change has impacted such extremes.

With a new framework they developed, Diffenbaugh’s team found that heat records were made both more likely and more severe for about 80 percent of the area of the globe with good observational data. For precipitation records, that percentage was about half.
