A14E:
Understanding and Attributing Extreme Weather Events and Their Impacts across Actors and Spatial Scales I (Half Session)


Session ID#: 10962

Session Description:
It is now widely accepted that “extreme event attribution” is possible, albeit in a probabilistic sense and recognizing the role of multiple causal factors. Annual assessments of the role of climate change in individual weather and climate events are being compiled using a range of approaches (BAMS:Peterson et al, 2012 & 2013, Herring et al., 2014). There is increasing interest in using event attribution in risk assessment, public communication, and, eventually, international negotiations. In order for the science to inform the latter, only attributing the role of climate change is likely insufficient and the relative roles of hazard and vulnerability need to be included when assessing impacts. This session aims to explore new developments in both the science and communication of attribution and would seek to include contributions from the detection and attribution, climate impacts, and disaster risk communities.
