Projection and impact assessment of global change

Anthropogenic forcings on global environment are expected to cause intensification of extreme events, sea level rise, ocean acidification, as well as large-scale ecosystem changes. The CMIP6 experimental protocol has been established, based on which modeling groups across the world are starting to provide environmental projection data toward 6th IPCC assessment report due in 2021. Various new types of studies, such as event attribution and coupling of socio-economic processes and Earth system dynamics, are also emerging in the field of global change projection. In addition, impact assessment studies using downscaling technique are becoming increasingly more important for grasping the significance of environmental changes for our society. Interactions and collaborations beyond boundaries of conventional scientific disciplines are desired for dealing with the issues of global change.
In this special issue SPEPS, we invite authors to contribute latest researches or reviews on global change from disciplinary and interdisciplinary viewpoints. The scope ranges over, but not limited to, development of climate/Earth system models, their applications on projections on global and regional scales, impact assessments with a particular emphasis on Asia, and cross-cutting studies with social scientists.
