Friday, February 3rd 2017
Speaker: Ed Larson, Pepperdine University
Subject: "Red Dawn Rising: the Sketchy History and Techno-thriller Prospects of Geoengineering"
Refreshments served at 3:25 p.m.

The global debate over the danger of human-caused climate change has spawned a secondary one over geoengineering as a possible human-instigated response with attention increasingly focusing on the intentional injection of sulfate aerosols into the stratosphere to cool the earth. Over the past two decades, this idea has moved from a crank concept supported by a few fringe technologists in Russia and the United States, such as H-Bomb physicist Edward Teller, to a theory whose study has been endorsed by such mainstream scientific organizations as the Royal Society, the National Academy of Sciences, and the Intergovernmental Panel of Climate Change. With a friendly ear in the Kremlin and now the White House, the world may see a red dawn rising for geoengineering. This lecture will review its sketchy past and techno-thriller future.
