The great failure of the climate models

...Should we trust these computer models of doom? 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.  Atmospheric scientist John Christy developed a global temperature record of the lower atmosphere using highly accurate satellite soundings. NASA honored him for this achievement, and he was an author for a previous edition of the U.N. report. He told a House Science Committee hearing in March 2017 that the U.N. climate models have failed badly. Christy compared the average model projections since 1979 to the most reliable observations — those made by satellites and weather balloons over the vast tropics. The result? In the upper levels of the lower atmosphere, the models predicted seven times as much warming as has been observed. Overprediction also occurred at all other levels. Christy recently concluded that, on average, the projected heating by the models is three times what has been observed.  [320]
