For over the past 200 years, the burning of fossil fuels, such as coal and oil, and deforestation, have caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. In this collection documents (1991-2009) the U.S. response to the threat posed by climatic change and global warming. The research behind the studies, reports, and analyses represents an exhaustive review of the facts, causes, and economic and political implications of a phenomenon that threatens every region of the world.
