This series offers a thorough introduction to and analysis of the relationship between climate and humanity: our linked prehistory, history, and likely future. Climate is the determining factor in where and whether life exists—why there is life on Earth and not on Mars and Venus; in specialized organisms where it is hot or cold, wet or dry, light or dark. Climatic change killed off the dinosaurs and brought prehistoric humans out of the trees and upright on their feet to search for food. And climatic change is threatening now to wipe out life on Earth—by drowning, boiling, suffocating, starving, or genetic destruction. These programs examine the nature of climate, what people have done to alter it, whether we are prepared to foot the costs of saving our planet, or to try to reverse the processes we have set in motion by attempting with scientific means to counter the deadly prospects which confront us. 6-part series, 26 minutes each.
