Betting Against Al Gore: ups ante to $100,000

Published August 16, 2007

(Chicago, Illinois – August 14, 2007) The latest challenge to the heavily promoted idea that global warming is man-made and likely to be harmful is a $100,000 reward offered by to the first person who can scientifically prove Al Gore’s theory that human beings are causing harmful global warming.

Gore continues to aggressively pursue his claim that harmful global warming is caused by man-made carbon dioxide emissions. Repeating the formula of fear used in his movie, An Inconvenient Truth, Gore continues his climate change crusade with a dramatic PowerPoint presentation, book tour, and concerts. His book signings double as campaign rallies and volunteers energize the crowd and collect petition signatures for Gore’s possible run for president.

At the center of the debate challenge is the question of whether man-made carbon dioxide causes global warming. This theory has become increasingly difficult to defend as:

  • evidence of natural climate variability due to solar cycles is more widely embraced in the scientific community;
  • the National Oceanic and Atmospheric Administration (NOAA) recently announced U.S. temperatures in the 21st century were not warmer than those before World War II; and
  • the Intergovernmental Panel on Climate Change (IPCC) recently released the comments of scientists whose reviews of the fourth assessment report were critical of global warming theory … and largely disregarded by the report’s lead authors. is offering a $100,000 reward to anyone able to prove two of the key hypotheses that need to be true if fear of global warming is justified.

The list of Gore debate challengers continues to grow as scientists, economists, and researchers dissect his extreme rhetoric and unjustified conclusions. joins best-selling author Dennis Avery (Unstoppable Global Warming), Lord Christopher Monckton (a science advisor to Margaret Thatcher), Bjorn Lomborg (Danish economist), author Michael Crichton, Dr. S. Fred Singer (Unstoppable Global Warming, former director of the U.S. National Weather Service), Dr. Tim Ball (historical climatologist), Prof. Ian Clark (University of Ottawa), and Prof. Richard Lindzen (Massachusetts Institute of Technology), among others.

Gore has refused all debate challengers to date. Joseph Bast, president of The Heartland Institute, notes, “Maybe it’s because climate alarmists tend to lose when they debate climate realists. Or because most scientists do not support climate alarmism.” The Heartland Institute has run ads worth more than $500,000 in the Wall Street Journal, New York Times, and Washington Times promoting a debate.
