To what extent has industrialization impacted Earth’s climate? How are researchers studying global warming? And what is being done to forestall the planet-wide ecological crisis looming over the horizon? This timely program makes generous use of computer models, 3-D animations, and high-tech imaging to explore these crucial questions. Analysis of ocean sediment, prehistoric trees and pollen, and air trapped in polar ice; the influence of forests, volcanic aerosols, and microbe activity on the greenhouse effect; increases in desertification, hurricane activity, and incidences of drought, flooding, forest fires, and mudslides; and sustainable and efficient energy sources are discussed.
