Explaining Extreme Events from a Climate Perspective

This BAMS special report presents assessments of how human-caused climate change may have affected the strength and likelihood of individual extreme events.

The U.S. Northern Plains and East Africa droughts of 2017, floods in South America, China and Bangladesh, and heatwaves in China and the Mediterranean were all made more likely by human-caused climate change, according to new research published today in the Bulletin of the American Meteorological Society (BAMS).

The seventh edition of the report, Explaining Extreme Events in 2017 from a Climate Perspective, also included analyses of ocean heat events, including intense marine heatwaves in the Tasman Sea off of Australia in 2017 and 2018 that were “virtually  impossible” without human-caused climate change. Also included are analyses of Australian fires and Uruguay flooding.

This is the second year that scientists have identified extreme weather events that they said could not have happened without warming of the climate through human-induced climate change.
