An impressive YouTube video has been making its rounds over the past week, appearing at first glance to show high-resolution satellite images of U.S. carbon dioxide emissions.
Rather than images from space, however, the Vulcan Project is actually a revolutionary new model of CO2 emissions building on and extrapolating from existing models of more conventional pollutants. The project, funded by NASA and the Department of Energy, is the work of a team at Purdue University in Indiana.
