role. However, the model was very simple and the calculation of the CO2 effect was lower than other estimates by a factor of about three, as noted in a footnote to the paper. The story made headlines in The New York Times. Shortly afterwards, Schneider became aware that he had overestimated the cooling effect of aerosols, and underestimated the warming effect of CO2 by a factor of about three. He had mistakenly assumed that measurements of air particles he had taken near the source of pollution applied worldwide. He also found that much of the effect was due to natural aerosols which would not be affected by human activities, so the cooling effect of changes in industrial pollution would be much less than he had calculated. Having found that recalculation showed that global warming was the more likely outcome, he published a retraction of his earlier findings in 1974. In a 1976 book The Genesis Strategy he discusses both long-term warming due to carbon dioxide and short-term cooling due to aerosols, and advocated for adopting policies that are resilient to future changes in climate. Media contributions Schneider was a frequent contributor to commercial and noncommercial print and broadcast media on climate and environmental issues, e.g., Nova, Planet Earth, Nightline, Today Show, The Tonight Show, Bill Maher's shows, Good Morning America, Dateline, The Discovery Channel, as well as appearances on the British, Canadian and Australian Broadcasting Corporations. Schneider commented about the frustrations and difficulties involved with assessing and communicating scientific ideas. In a January 2002 Scientific American article, he wrote: In 1989, Schneider addressed the challenge scientists face trying to communicate complex, important issues without adequate time during media interviews. This citation sometimes was used by his critics to accuse him of supporting misuse of science for political goals: For the original, together with Schneider's commentary on its misrepresentation, see also American Physical Society, APS News August/September 1996. Honors 1991 AAAS Award for Public Understanding of Science and Technology. 1992 MacArthur Fellow "Genius Award". 2002 Elected to the National Academy of Sciences. Chair of the American Association for the Advancement of Science's Section on Atmospheric and Hydrospheric Sciences (1999–2001). The Intergovernmental Panel on Climate Change (IPCC), to which Schneider made very significant contributions, shared in the 2007 Nobel Peace Prize. Personal Schneider was married to the biologist Terry Root. Schneider was a survivor of an aggressive cancer, mantle cell lymphoma. He
