Attribution of anthropogenic influences on weather events has developed into an advanced science over the past decade.  This session invites presentations that (1) quantify and understand the contributions of anthropogenic climate change and natural climate variability to the likelihood, magnitude, and characteristics of weather events and (2) develop attribution methodologies using, for example, statistical and dynamical climate models.  We welcome contributions on a broad range of events including but not limited to flooding, drought, heat extremes, tropical cyclones, mid-latitude cyclones, severe storms, and winter storms.

Keynote Speakers: Céline Bonfils (Lawrence Livermore National Laboratory), Friederike Otto (Oxford), Marty Hoerling (NOAA), Suzana Camargo (Columbia University)
