Anthropogenic forcings on the global environment are expected to cause intensification of extreme events, such as sea-level rise, hurricanes and typhoons, ocean acidification, and deoxygenation, as well as regional-scale ecosystem changes. Under the international project CMIP6, Earth System modeling groups across the world performed simulations and published projection data, which made invaluable contributions to the 6th IPCC assessment report (AR6) published in August 2021. After its publication, AR6 attracted much attention from the general public due to a number of extreme weather events that occurred on a global scale in the following years and their arguable links to climate change. Other than CMIP6, new types of studies, such as event attribution and coupling of socio-economic processes and Earth system dynamics, are emerging in the field of global change projections. In addition, analysis of observational data is becoming increasingly important for assessing the credibility of model projections on the global environment. Interactions and collaborations beyond the boundaries of conventional scientific disciplines are desired for dealing with the issue of global changes and their impacts. This session hosts the latest research findings with a view to model projections and interdisciplinary collaborations including those with social sciences. Presentations on the direction of model development for the possible CMIP7, the next international project for climate change projection, are also welcome.
