CMIP6

Model-based, climate projection data is derived from the Coupled Model Inter-comparison Project-Phase 6 (CMIP6). CMIP is a standard framework for the analysis of coupled atmosphere-ocean general circulation models (GCMs) providing projections of future temperature and precipitation according to designated scenarios. CMIP efforts are overseen by the World Climate Research Program, which supports the coordination for the production of global and regional climate model compilations that advance scientific understanding of the multi-scale dynamic interactions between the natural and social systems affecting climate.

CMIP6 projections are shown through five Shared Socioeconomic Pathway (SSPs) Scenarios, designated by total radiative forcing (W/m2) reached by the end of the century. Scenarios are used to represent the climate response to different plausible future societal development storylines and associated contrasting emission pathways to outline how future emissions and land use changes translate into responses in the climate system. These represent possible future greenhouse gas concentration trajectories adopted by the Intergovernmental Panel on Climate Change (IPCC).

CMIP6 global products are downscaled and bias corrected at 0.25-degree, available for 1950-2100
