Description
In the last half of the 20th century, scientists began understanding that industrialization and the effects of explosive population growth were affecting the fundamental structure and composition of earth's atmosphere. Man's ever-increasing thirst for energy, quenched by the burning of fossil fuels, has dramatically increased greenhouse gases in the lower atmosphere. This 2-disc set examines and explains this phenomenon, and looks into the future...
Description
Leading environmental policy experts and scientists explain the phenomenon of global warming, and present recommendations for global action to counter the threat. They discuss the biotic consequences of global warming, the effects on physical systems such as the soil and water supplies, the global greenhouse gases, and public policy responses. The recommendations include curbing the production of greenhouse gases such as carbon dioxide and methane,...
Description
This documentary addresses the major environmental challenges of our century by investigating a forgotten gas from Earth's past. With up to 20 times the warming potential of carbon dioxide, methane emissions could threaten life on earth. From the Arctic Ocean to Siberia to the Antarctic, what impact will this greenhouse gas have on our climate? Join scientific teams from the U.K., Russia, Denmark, Canada, France, and the U.S. as they study the effects...
Description
Former Vice President Al Gore explains the facts of global warming, presents arguments that the dangers of global warning have reached the level of crisis, and addresses the efforts of certain interests to discredit the anti-global warming cause. Between lecture segments, Gore discusses his personal commitment to the environment, sharing anecdotes from his experiences.

In the global-warming debate, definitive answers to questions about ultimate causes and effects remain elusive. In Global Warming: Myth or Reality? Marcel Leroux seeks to separate fact from fiction in this critical debate from a climatological perspective. Beginning with a review of the dire hypotheses for climate trends, the author describes the history of the 1998 Intergovernmental Panel on Climate Change (IPCC) and many subsequent conferences....
10) Climate change and the global harvest: potential impacts of the greenhouse effect on agriculture

Publisher description: If the predictions of many atmospheric scientists on global warming are realized, the mean change in temperature of the earth's surface will rise by several degrees--a warming that is likely to trigger a series of changes affecting the hydrologic regimes of entire regions. These predictions have serious implications for the future of food production and global food security, which depend on the predictability of the climate...

"Global warming is a fact. The temperature of the Earth is rising faster than at any time in recorded history, and in the next century, is likely to increase by up to six degrees." "Beating the Heat is a lively, concise, and rigorously-researched exploration of this imminent crisis. Environmental specialist John Berger shows the causes and consequences of climate change, rebuts the deceptive arguments of climate change skeptics, and presents practical...

"Last year, awareness about global warming reached a tipping point. Now one of the most dynamic writers and one of the most respected scientists in the field of climate change offer the first concise guide to both the problems and the solutions. Guiding us past a blizzard of information and misinformation, Gabrielle Walker and Sir David King explain the science of warming, the most cutting-edge technological solutions from small to large, and the...
Description
Over the past 100 years, the mass consumption of fossil fuel, especially in America, has contributed to a dangerous global warming that is now beginning to adversely impact our lives and promises to do far greater damage if we continue to ignore its warning signs. This cautionary documentary offers a guide to the impacts of global warming on the U.S. and gives measures that can be taken to reverse this trend.
Description
"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,...
