Introduction to the Lecture

In the context of global climate change, extreme weather and climate events are occurring with increasing frequency, gradually becoming a new climate normal. Concurrently, the rapid advancement of human socio-economic development not only exacerbates ongoing climate change but also amplifies the ecological and economic losses resulting from these extreme events. A thorough understanding and assessment of the formation mechanisms and impacts of such events hold significant scientific and practical importance for enhancing climate change adaptation strategies and informing future policy-making. This report will provide an overview of the speaker's research findings on extreme weather and climate events, with a particular focus on the potential implications of a possible weakening of the Atlantic Meridional Overturning Circulation (AMOC) for global and regional climate change in the future.

Profile of the Speaker

Ma Qiyun, who received his doctorate from the University of Hamburg, Germany, now works at Alfred Wegener Institute for Polar and Marine Research (AWI) in Germany. From 2021 to 2024, he worked as a postdoctoral fellow at the University of Hamburg and AWI Institute in Germany. His main research direction involves climate change and its simulation, focusing on the causes, evolution laws and social impact assessment of extreme weather and climate events, and studying the impact of future Atlantic Meridional Overturning Circulation (AMOC) changes on global and regional climate. In recent years, he has contributed to and published over 30 academic papers, including several first-authored publications in prestigious journals such as Science Advances, Journal of Climate and Climate Dynamics.
