Joint Climate and Air Quality Impacts

GISS researchers explore how to characterize a broad range of impacts of potential emissions trajectories, with a particular emphasis on near-term emissions pathways designed to reduce multiple environmental damages. We evaluate the effects of the full suite of climate-altering pollutants emitted by particular activities and how these might change under different policies, and along with assessing the effect on global temperatures we evaluate the simultaneous responses of regional temperatures, precipitation and air quality (including the impact on human and ecosystem health of improved air quality).
