Abstract:

Policy makers and the public are increasingly concerned about the impacts of climate change, and this requires richer, fine-scale information on current and future climate conditions at regional scales. The Atlas chapter coordinates with other chapters of Working Group I (WGI) report in the IPCC Sixth Assessment Report (AR6) to assess basic information on observations, attributions, and projection of regional climate change, and establishes an online interactive atlas system. The Atlas consists of two parts. The Atlas chapter assesses climate change in each region based on new reference regions, and focuses on observed trends and attributions of surface temperature and precipitation, and projected future changes. The Interactive Atlas, a new component of the AR6 WGI report, provides comprehensive information on observed and predicted climate change and climate change attribution over time in the form of interactive maps based on observed, global (CMIP5 and CMIP6), and regional (CORDEX) model projections.
