Monsoons across Multi-scales: Summary of Fourth Conference on Earth System Science

The evolution and future projection of the regional and global monsoons, one of the major components of Earth climate system in the low-latitudes and middle-latitudes, has long been the research focus in the paleoclimate and modern climate communities. Session 4 of the 4^th Conference on Earth System Sciences (CESS) in Shanghai focused on the evolution, variability, and driving mechanism of regional and global monsoon system across multiple timescale, and the role of the monsoon system in changes in the Earth system. During the session, the issues of features of past and contemporary monsoons based on observation data and geological reconstruction, model simulation of past and contemporary monsoons, and response of monsoon climate to the past and present global warming were intensively discussed. The future research directions were also addressed.
