Again, from Heartland:
Climate models used by the United Nations Intergovernmental Panel on Climate Change and other climate groups to predict future temperatures have failed miserably at predicting climate in recent years, new data show.
Scientists overseeing temperature data collected by NASA satellite instruments compared real-world temperatures in the tropical troposphere since 1979 to 73 climate prediction models produced by international government agencies, universities, and other climate groups, including 19 models produced by U.S. agencies, universities, and climate groups. All 73 models predicted substantially more warming than actually occurred, with the mean of the 73 models predicting three times as much warming as actually occurred.
John Christy, the Distinguished Professor of Atmospheric Science and Director of the Earth System Science Center at the University of Alabama at Huntsville, provided the data. Christy’s colleague Roy Spencer published the data charts on his website.
