EDINBURGH, Scotland, April 9 (UPI) -- Environmentalists and climate scientists, facing public skepticism, are losing the debate on global warming, a U.S. scientist who first raised the issue says.
James Hansen, director of the NASA Goddard Institute for Space Studies, who issued warnings about man-made climate change as early as the 1980s, said public skepticism is increasing even in the face of growing scientific acceptance of the reality of global warming.
