Ronald Bailey Wonders If the U.N.’s IPCC Climate Models Can Be Trusted?

NewGlobalWarmingImageMeryll: DreamstimePretty much everyone concerned with this issue
agrees the world is warming. But what is causing the planet to warm
up? The new scientific report from the U.N.’s Intergovernmental
Panel on Climate Change (IPCC) issued earlier this week flatly
declared that it is “extremely likely that human influence has been
the dominant cause of the observed warming since the mid-20th
century.” One way to probe this claim is to see how well the
computer climate models relied upon by the IPCC do at simulating
observed temperature trends. The IPCC says that the models do just
fine, but Reason Science Correspondent Ronald Bailey
suggests that there is room for doubt.
