"Ken Caldeira, of the Carnegie Institution for Science’s Department of Global Ecology at Stanford University—one of the world’s leading scientists in climate change—presents policy-relevant science to help solve the carbon-climate problem. Hear about carbon-neutral energy for economic growth and environmental preservation—and the back up plan: goengineering. Beyond numerous scientific journals, he’s written for The New Yorker and The New York Times, contributed to reports that won the Nobel Peace Prize, has testified before Congress and the British Parliament and will organize a session on geoengineering in Copenhagen."
