S. Fred Singer, interviewed by John F. McManus The following viewpoint is an interview of atmospheric physicist S. Fred Singer conducted by John F. McManus. Singer disputes the contention that human activities are causing the global climate to warm significantly. Global temperatures fluctuate for many reasons, he argues, not all of them fully understood. Efforts to reduce greenhouse gases, as prescribed in an international treaty negotiated in Kyoto, Japan, in 1997, may harm the economies of industrialized nations but will probably have little effect on the world’s climate. Singer heads the Science and Environmental Policy Project, a policy research group, and is a former director of the U.S. Weather Satellite Service. His books include Hot Talk, Cold Science: Global Warming’s Unfinished Debate. McManus is publisher of The New American magazine.
