Mr. Gore is the author of An Inconvenient Truth, a best-selling book on the threat of and solutions to global warming, and the subject of the movie of the same title, which has already become one of the top documentary films in history. In 2007, An Inconvenient Truth was awarded two Academy Awards for Best Documentary Feature and Best Original Song.

Since his earliest days in the U. S. Congress 30 years ago, Al Gore has been the leading advocate for confronting the threat of global warming. His pioneering efforts were outlined in his best-selling book Earth in the Balance: Ecology and the Human Spirit (1992). He led the Clinton-Gore Administration's efforts to protect the environment in a way that also strengthens the economy.

Al Gore was born on March 31, 1948, the son of former U.S. Senator Albert Gore, Sr. and Pauline Gore. Raised in Carthage, Tennessee, and Washington, D.C., he received a degree in government with honors from Harvard University in 1969. After graduation, he volunteered for enlistment in the U.S. Army and served in the Vietnam War. Upon returning from Vietnam, Al Gore became an investigative reporter with the Tennessean in Nashville, where he also attended Vanderbilt University's Divinity School and then Law School.

The Anthropogenic Global Warming hypothesis is summarized by Warren Meyeras follows:

  1. The world has been warming for a century, and this warming is beyond any cyclical variation we have seen over the last 1000 or more years, and beyond the range of what we might expect from natural climate variations.

  2. Almost all of the warming in the second half of the 20th century, perhaps a half a degree Celsius, is due to man-made greenhouse gases, particularly CO2

  3. In the next 100 years, CO2 produced by man will cause a lot more warming, from as low as three degrees C to as high as 8 or 10 degrees C.

  4. Positive feedbacks in the climate, like increased humidity, will act to triple the warming from CO2, leading to these higher forecasts and perhaps even a tipping point into climactic disaster

  5. The bad effects of warming greatly outweigh the positive effects, and we are already seeing the front end of these bad effects today (polar bears dying, glaciers melting, etc)

  6. These bad effects, or even a small risk of them, easily justify massive intervention today in reducing economic activity and greenhouse gas production
