When Can Decision Analysis Improve Climate Adaptation Planning?
A paper by MARISA team members Rui Shi and Benjamin Hobbs proposes two procedures to identify climate adaptation decision problems that would most benefit from using formal decision analysis methods. Careful consideration of uncertainty and flexibility may result in better decisions but requires additional effort. These procedures can help decisionmakers understand in which situations a comprehensive analysis is worthwhile and in which situations a simple analysis should suffice. Download the paper [PDF].

Responding to the Risk of Extreme Heat in New York City
RAND’s Jaime Madrigano, working with the Consortium for Climate Risk in the Urban Northeast (CCRUN), partnered with the New York City (NYC) Department of Health and Mental Hygiene and others to develop a heat vulnerability index (HVI) for NYC and address the impacts of extreme heat on city residents. The HVI informed many of the initiatives in Cool Neighborhoods NYC, the mayor’s plan to protect against the worst effects of rising temperatures from climate change.
