Explaining Extreme Events from a Climate Perspective (2019)

Published: 
January 2021
From: 
American Meteorological Society

This series of BAMS special reports presents assessments of how human-caused climate change may have affected the strength and likelihood of individual extreme events. The series has been published annually since 2011.

The ninth edition of the report, Explaining Extreme Events in 2019 from a Climate Perspective, presents 15 new peer-reviewed analyses of extreme weather across four continents and one sea during 2019. It features the research of 77 scientists from 7 countries looking at both historical observations and model simulations to determine whether and by how much climate change may have influenced particular extreme events.
