claim: Let’s find out by comparing the actual temperatures since 1979 with what the 32 families of climate models used in the latest U.N. report on climate science predicted they would be.
evidence: Models referenced by the Intergovernmental Panel on Climate Change ( IPCC ) predict that global temperatures are likely to increase by 1.1 to 6.4 °C ( 2.0 to 11.5 °F ) between 1990 and 2100.
