Summary: If global warming cycles are natural phenomena, why should humans alter their consumption habits and behavior? Have we really accelerated climate change? This program studies the causes of ozone depletion and the buildup of greenhouse gases-examining both sides of the highly politicized issue while making the case that current warming trends are in fact human-caused. Outlining the importance of...

Summary: As visually spectacular as it is informative, this program thoroughly surveys the world's varied climate systems. Using simple color-coded maps based on the Koppen classification system, the video identifies the characteristics of the following zones: humid tropical climates, wet-dry tropics, dry climates, subtropical and mid-latitude deserts and steppes, humid mid-latitude climates, humid...

Summary: People everywhere are interested in the weather, but how does it all work? Beginning with Earth's atmosphere-its evolution, its gaseous composition, and its four regions-this video takes a close look at how conditions combine to create climate and weather. Topics include the Koppen Climate Classification System; weather prediction; types of clouds and precipitation; thunderstorms, tornadoes,...

Summary: To predict weather and understand climates, researchers use physics, environmental science, mathematics, and information technology to interpret huge amounts of oceanic, atmospheric, and terrestrial data. Filmed with the assistance of Australia's Bureau of Meteorology, this program introduces the allied sciences of meteorology and climatology. After explaining how the sun, wind, and clouds...

Summary: How serious is the "greenhouse effect" on global climate and the environment? Very, says Dr. Jessica Tuchman Mathews, a Ph.D. in biochemistry and biophysics. We are now facing the specter of the "greenhouse effect," the prospect of overloading the earth's atmosphere with gases released when industrial nations burn fossil fuels like coal and oil, and the Third World strips its forests to farm...

Summary: 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 cases where seeding appears to have been successful. This program shows how migration in the Sahel has altered regional climate; examines the...

Summary: 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 relationship between sunlight and CO2, explains why the atmospheres of Mars and Venus cannot sustain life, theorizes about the disappearance of...
