The Accuracy of Climate Models – “The Signal and the Noise: The Art and Science of Prediction” – Nate Silver

November 24th, 2012 · No Comments · Environmental Policy, Policy, Politics, Prediction, Statistics

Emanuel’s concerns are actually quite common among the scientific community: climate scientists are in much broader agreement about some parts of the debate than others. A survey of climate scientists conducted in 2008 found that almost all (94 percent) were agreed that climate change is occurring now, and 84 percent were persuaded that it was the result of human activity. But there was much less agreement about the accuracy of climate computer models. The scientists held mixed views about the ability of these models to predict global temperatures, and generally skeptical ones about their capacity to model other potential effects of climate change. Just 19 percent, for instance, thought they did a good job of modeling what sea-rise levels will look like fifty years hence.
