One of the most hotly debated subjects of modern politics is the growing environmental hazards created by industry. According to scientists, global warming is a sign of eventual destruction. Yet, developing countries are putting more and more toxins into the atmosphere. Nova explores the boundaries of this fierce issue in its two-hour special Nova: What's Up With the Weather? Traveling all over the world, the PBS program visits sites where greenhouse gases have caused damage. In the Maldives Islands, sea levels are ever increasing. Greenland serves as secretary to global warming, keeping 10,000 years of ecological changes in its soil. While Washington debates legislation to control energy use, China and India become leaders in environmental pollution. Nova asks some tough questions about the future of the earth itself, and the answers are frightening.
