How long ago did glaciologists and environmentalists begin to worry about global warming? How many scientists have battled over the earth's future, one group believing in nuclear winter and the other a world that makes the vision of Soylent Green, where our planet is a dry roated peanut where one tree is a sight only the rich may see, a reality?
