Schewe

My research revolves around the impacts of climate change on human societies and on the environmental conditions they depend on. I work with global models of biophysical climate impacts, through the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP). In my group, we study how patterns of human migration and mobility are directly or indirectly linked with climate impacts, and how they might evolve in a warming world. Through the FutureLab, we explore effects on the conditions for peace and the risk of conflict. My simultaneous research on the physical changes in the climate system and the biosphere underpins these investigations.
