The central issue discussed in this book is what is now widely known as "Global Warming and Climate Change". It started in the early 1980s as the "greenhouse effect"--Warming of the atmosphere due to the absorption of earth's outgoing long wave radiation by the greenhouse gases. The level of coverage that the western mass media devoted to global warming was low prior to 1988. But interest increased significantly after the U.S. drought in 1988, and related U.S. Senate testimony by Dr. James E. Hansen, NASA's chief climate scientist, who attributed the abnormally hot weather to global warming. --Book.
