Global Average Temperature 1900 to 2100

Observed and projected changes in the global average temperature under three IPCC no-policy emissions scenarios. The shaded areas show the likely ranges while the lines show the central projections from a set of climate models. A wider range of model types shows outcomes from 2 to 11.5ºF.1 Changes are relative to the 1960-1979 average.  Image References: Smith et al.2; CMIP3-A3
