This talk discusses the current knowledge on aspects of detection, attribution, and projection of global and regional monsoons under climate change, focusing on land monsoon rainfall that provides water resources for about 70% of the world population. Monsoon has been progressively studied since the 17th century, yet only recently have regional monsoons been recognized as a global system. The talk will begin with an elaboration of the concept of global monsoon and related debating issues, followed by a description of the observed global monsoon changes and a discussion of their primary drivers, in particular, the attribution of the recent trends and exploration of decadal variability and predictability of Northern Hemisphere land monsoon precipitation. Continued global warming and urbanization over the past century have already caused a significant rise in the intensity and frequency of extreme rainfall events in all monsoon regions. The future changes of global and regional monsoons projected by complex climate models will be reviewed with particular emphasis on the key physical processes that may be responsible for the projected changes. Toward the end of the talk, I will discuss models’ common biases, missing and poorly resolved processes, sources of projected uncertainties, and conceivable ways forward.

About Nordenskjöld Lecture
The Nordenskjöld Lecture is the high profile session of the Earth System Science seminar series at the University of Gothenburg, designed to bring the leading world researchers to share their thoughts and perspectives. The lecture honours the memory of Otto Nordenskjöld, the first August Röhss professor of Geography and Ethnography at our university, who organised and led the first Swedish Antarctic expedition 1901-1903.
