报告摘要：

This talk gives an overview of recent studies relating climate change and air pollution at the decadal to multi-decadal time scale. The first part focusing on interactions will review recent works of how global warming affect aerosol distribution, and in turn, how aerosols affect mean and extreme precipitation and circulation changes, which could consequently impact air pollution itself, completing an intrinsic two-way feedback loop. The second part will address the joint occurrence of heat extremes and air pollution, including haze and ozone, raising awareness of their broader impact on human health and crop yield. Some concluding thoughts are given on how to mitigate the near-term warming rates by achieving co-benefits of air quality improvement, while avoiding the temporary shock of aerosol unmasking. A novel yet simple integrated human-Earth modeling framework is introduced to further demonstrate the importance of cutting non-CO2 pollutants to stabilize global warming.

报告人简介：

Dr. Yangyang Xu received BS in Atmospheric Sciences from Peking University in 2008 and Ph.D. in Earth Sciences from Scripps Institution of Oceanography, University of California, San Diego in 2014. He was an Advanced Study Program fellow in National Center for Atmospheirc Reasearch during 2014 and 2016. Dr. Xu joined the Department of Atmospheric Sciences at Texas A&M University as an Assistant Professor in 2016 and was promoted to Associate Professor in 2022. Dr. Xu teaches graduate and undergraduate courses in climate modeling, climatology, atmospheric physics, and computer programming. Dr. Xu has chaired 8 graduate student committees and served on more than 10 others. Dr. Xu's research focuses on climate modeling with a specialization in climate change attribution, impact, adaptation, and mitigation. He won the Global and Environment Change Early Career Award from American Geophysical Union in 2019 due to “outstanding contributions in research, educational, or societal impacts in the area of global environmental change”.
