PBS Nova - Global Warming: What’s Up With the Weather

Deadly flooding in Africa. Catastrophic hurricanes in the U.S. Record-high temperatures worldwide. Are these natural, temporary glitches in our global climate, or is the devastation the result of global warming? The weather is different now — but why?
Find out when NOVA and FRONTLINE join forces to determine What’s Up with the Weather? Man-made carbon dioxide has overloaded the earth’s atmosphere. With demand for fossil fuels increasing daily, experts predict emission levels will triple in the next 100 years. But the greenhouse effect remains the subject of heated debate among scientists, climatologists, and futurists. Some believe the earth’s temperature will rise by nearly 10 degrees, melting arctic ice caps and, paradoxically, bringing about a new Ice Age. Others believe the weather will stay relatively normal. Who’s right? Decide for yourself as this riveting two-hour special gives you the fascinating — and occasionally frightening — forecast for the future.
