For the sustainability of biosphere and human society, it is crucial to in-depth understand Earth climate system changes on different timescales in Quaternary. Anthropogenic forcing is also strongly affecting different aspects of human living environments, natural ecological through physical and chemical climatic perturbations, especially in East Asia with swift economic takeoff in the recent decades. We welcome climate and environmental reconstructions based on natural archives, proxy data, numerical simulations especially on the topics of monsoon, precipitation belt shifting, typhoon, and drought histories in Quaternary and Anthropocene. Atmospheric and oceanic interactions, greenhouse gases radiative forcing and anthropogenic forcing impact from regional to global scale are also welcomed.
