The desiccating Four Corners drought, intense heat waves on the Iberian peninsula and in northeast Asia, exceptional precipitation in the Mid-Atlantic states, and record-low sea ice in the Bering Sea were 2018 extreme weather events made more likely by human-caused climate change, according to new research published today in the Bulletin of the American Meteorological Society (BAMS).

The eighth edition of the report, Explaining Extreme Events in 2018 from a Climate Perspective, presents 21 new peer-reviewed analyses of extreme weather across five continents and one sea during 2018. It features the research of 121 scientists from 13 countries looking at both historical observations and model simulations to determine whether and by how much climate change may have influenced particular extreme events.
