Multimedia | When 1+1=3; Applying a Joint Hazard Framework to Climate Risk Management

Nov, 10 2015

The Earth Institute and the SEAS Colloquium in Climate Science present the first Extreme Weather and Climate Seminar, When 1+1=3; Applying a Joint Hazard Framework to Climate Risk Management.

Most of the large municipalities of the Northeastern U.S. have conducted adaptation assessments that include downscaled climate projections. In these assessments, each climate variable has generally been considered independently, and downscaling methodologies have generally not been tailored to the extremes of a variable?s distribution. In the wake of events such as Hurricane Sandy, stakeholder need and scientific advances are increasingly converging towards assessments focused on extreme events from a joint hazards perspective, across multiple climate variables. This presentation will focus on two examples: 1) heat stress, based on combined impacts of high temperatures and high humidity, and 2) coastal flood risk associated with combined impacts of sea level rise and changes in coastal storms. This talk will demonstrate how the joint hazards approach can lead to large changes in projected extreme event frequency, relative to downscaling approaches that treat climate variables as independent.
