报告简介：Cities are where major human-perceived climate change impacts occur. The uniqueness of local urban climates such as urban heat island (UHI), a common phenomenon of relative urban warmth compared to surrounding rural areas, further exacerbates the heat stress induced by non-local greenhouse gas-induced warming. The associated socioeconomic impacts (such as public health, energy, and workplace productivity) are often much higher in urban areas than over other landscapes because of the concentrated population. These hazardous risks are projected to be further worsened due to rapid urbanization coupled with climate change. Understanding the mechanism of urban heat, its interaction with climate change, and the associated impacts is essential for effective urban climate adaptation and resilient development. Here in this seminar, I will present some of our recent works that combine Earth system modeling, theory, remote sensing, and physics-informed machine learning to understand the urban heat island, humid heat stress and exposure, future change, variability and uncertainty, and their implications to public health and urban adaptation at large scales. In the second part, I will present recent advances in representing urban-scale processes and dynamics in global-scale Earth system models.
