The May/June issue of Technology Review, Published by MIT, Features an Article "Planning for a Climate-Change World" by David Talbot

Summary

The article highlights the challenge of providing regional climate change projections needed by policy makers to translate the information to something useful at the city or state level. Talbot describes the subgrid elevation approach, pioneered by PNNL scientists Ruby Leung and Steve Ghan and funded by DOE Office of Biological and Environmental Research, to simulate climate effects on local hydrology. The article features two detailed graphics of mountain snowpack and potential changes in a future climate simulated using the subgrid approach, and discusses the need for a multi-model approach using global and regional models to address uncertainty in projecting water resources impacts.
