The December issue of National Geographic Magazine http://ngm.nationalgeographic.com/ features the work we've done here at MIT and with Climate Interactive (http://climateinteractive.org) on mental models of climate change in their "Big Idea" feature (p. 26-29 of the print edition; online at http://ngm.nationalgeographic.com/big-idea/05/carbon-bath) . They did a nice job with the art and in conveying some complex ideas clearly.
