If the threat of global warming has been created by our reckless use of technology, can we use technology to eliminate the threat? We could try to cool the earth by deliberately polluting the atmosphere, as volcanoes do, but suppose we overcooled the planet, creating another ice age? This program suggests some less drastic solutions to the problem of global warming: reducing CO2 emissions; harnessing the energy of the sun and the wind; using nuclear power; conserving energy; curbing or stopping the use of CFCs; and preserving the rainforest. But the basic fact is that greenhouse gases are produced by fundamental biological processes, and there is no reasonable way to stop their proliferation. It may also be taken as a given that, while individuals may be able to adapt to climatic change, societies cannot. (26 minutes)

The Greenhouse Effect
View Video Clip
A life-sustaining envelope of gas surrounds the earth. This atmosphere contains oxygen, CO2, water vapor, and other gases-it is what generates climate, which affects all living beings. This program analyzes the sun's gradual brightening and the relat...(more details)
 
Sun, Sunlight, and Weather Patterns
View Video Clip
Climate is a changing phenomenon, the first signs of alteration appearing in its day-to-day behavior-i.e., the weather. One readily observable recent climatic change is the increase in the number and ferocity of giant weather events like hurricanes. ...(more details)
 
Global Warming
View Video Clip
The history of Earth has been a history of temperature change; people and animals have historically moved to better climes, richer pastures, and areas of more abundant food. The problem now is that "somewhere else" is already occupied; meanwhile, tem...(more details)
 
Civilization and Climate
View Video Clip
Changing climate probably played the decisive role in drawing hominids out of the trees, up on their hind legs, and off in search of food whose supply had been dispersed by the replacement of rainforests by grasslands. Migrations were motivated by th...(more details)
 
Modifying the Weather: The Case of the Man-Made Desert
View Video Clip
By building roads, watering crops, and grazing cattle, we are constantly changing the climate. We may also modify the weather by cloud seeding, though there is no scientifically accepted proof that rain or snow would not have occurred naturally in c...(more details)
