 | by Stephen G. Benka, Physics Today. An article relevant to GSS Climate Change chapter 7. Excerpt: ...Currently there are about 20 climate models in use around the world that generate the indicators—including temperature, precipitation, clouds, and water vapor—on which the Intergovernmental Panel on Climate Change bases its projections. The largest uncertainties in the IPCC assessments—the most recent was in 2007—arise from how the models handle the complex feedback mechanisms of clouds and water vapor. Until recently, the “ground-truth” data for the simulations were sparse and provided climate scientists with incomplete knowledge. But that has changed with data from the A-Train constellation of satellites during 2006–09....
