Despite widespread scientific acceptance of the global warming theory, it remains a highly contentious subject. This program studies divergent points of view contributing to the global warming debate, untangling a morass of political and scientific concerns and providing a wealth of historical background on the issue. Is the greenhouse effect as dangerous as theorized, or is that simply bad science? What effect on human life and the world economy can be expected in the coming years? Will the global community ever agree on a concerted plan of action? These and other questions shed light on the dominant environmental issue of our time. A BBCW Production. (60 minutes)
