Kerry Sheridan, AFP: Dr. James Hansen addresses the topic of catastrophic man-made global warming. He considers it so urgent as to publish it before it is peer reviewed. He claims it is urgently necessary to tax fossil fuels (in the United States) and greatly reduce their use or (American) kids will suffer from man-made extremes in the climate/weather. Environmentalists for Nuclear Energy - USA presents their photographic evidence. People around the world, who depend on fossil fuels, disagree with Dr. Hansen about taxing and stopping use of fossil fuels.
