Study of regional extreme climate and its impact on air quality and health in US

摘要

After applying the dynamical downscaling technology, the regional air quality model showed relatively good performance compared with observations. Under RCP scenarios, due to emission reduction, the PM_(2.5) was projected to decrease across US, which is promising for future human health. However, as our recent study shows the intensity and duration of heat waves in US are projected to increase dramatically in particular under RCP 8.5, and the mortality risks due to the heat waves may be an order of magnitude higher than present conditions. Thus, it is urgent to take effective mitigation and adaptation measures to prevent heat mortality impact.
