Evidence has been mounting to suggest that anthropogenic climate change will cause many classes of high impact weather extremes (precipitation extremes, temperature extremes and climate related water sustainability) to increase in severity, duration, and/or frequency. However, recent high-profile adaptation and mitigation efforts and meetings have been largely unsuccessful. This can be attributed in part to the cascading uncertainties in climate change and extremes at increasingly granular spatial scales and the difficulty in translating such uncertainties from the scientific context to the realm of policy-making. Our collaboration at the intersection of law and science seeks to develop legal and policy constructs that characterize the uncertainty associated with climate extreme modeling. The objective is to give scientists further tools to communicate their findings in a way that will allow policy and law makers to develop realistic regulatory frameworks and constructs. From the policy perspective, we seek to develop regulatory frameworks to better account for the methodology and findings of weather extreme scientific modeling.
