 Global surface temperature changes in °C relative to 1850-1900. These changes were obtained by combining CMIP6 model simulations with observational constraints based on past simulated warming, as well as an updated assessment of equilibrium climate sensitivity . Changes relative to 1850-1900 based on 20-year averaging periods are calculated by adding 0.85°C  to simulated changes relative to 1995-2014. Very likely ranges are shown for SSP1-2.6 and SSP3-7.0 . Assessments were carried out at the global scale for , ,  and .
