Overall a pretty good film that avoids the hysterics of the "man-made global warming" advocates (MMGWA). The scientific information presented demonstrates that global warming exists, but whether it is man-made is highly questionable. The film also exposes the unintended consequences of reactionary environmentalism, ie, banning of DDT leading to millions of deaths from malaria and the inability of third world countries to emerge from poverty because they lack electrical power.About the only criticism is the comments about global warming being good because fewer people will freeze to death each year. This type of comment is silly. People die every year during heat waves too and a MMGWA could make the same case. Overall, very good otherwise.
