NOTE: Models don't actually project temperatures in degrees centigrade per decade, they predict the forcing effect of the various feedbacks for a given rise in carbon gas concentration, and the temperature rise per decade is inferred from that. In the case of the 17 models reviewed in the Geophysical Research Letters journal, ten of them accurately predicted the actual CO2 concentration increase and matched actual temperature data. Four matched actual temperature data when their CO2 assumptions were adjusted to match actual CO2 concentration. Two were overestimates, and one was an underestimate.
