Global Temperatures Projected to Rise Significantly by Century's End

Change in average global surface temperature compared to the preindustrial average (1850-1900)

This chart shows the change in average global surface temperature compared to the preindustrial average (1850-1900). It includes warming projections based on scenarios where the world continued with climate-related policies from around 2015 and 2022.
