The global average surface temperature for 2081-2100 is likely to be 0.3°C in the most optimistic scenario and 4.8°C in the most pessimistic scenario above the average of 1986-2005.

Global average surface temperature rise projected by an ensemble of models

Global average surface temperature rise (relative to the average temperature of 1986-2005) projected by an ensemble of models. Red and blue solid lines are multi-model mean under RCP8.5 and RCP2.6 respectively, with shading representing the uncertainty range. The black solid line represents the simulation for the 20th century. The coloured vertical bars on the right show the uncertainty range of the average over the period 2081-2100 for all scenarios, with the mean value given as a horizontal line. (Source: IPCC AR5)
