Global Change: Windows of Inquiry

Presented by some of the foremost experts on global change in North America, with footage from the islands of the Arctic to the Salton Sea in California, this series explains the complex issue of global change in a way that is both clear and compelling. Looking at population growth, atmospheric and bio-diversity change, and environmental quality, this program shows evidence of what damage has been done, along with scientific projections of what is likely to occur if consumption of the earth's resources is not reduced.åÊThis program examines evidence of global change from the aspect of what has been induced by human activities and what is a result of natural process. An explanation of how each of the earth's ecosystems is tied together reveals why changes in one affect the others. The program also uses evidence of past global change to predict what we can expect in the future.
