There has been virtually no overall global warming since 2001. Christopher Monckton, a former adviser to Margaret Thatcher, reminded the conference that temperatures "have been plummeting at a rate equivalent to 11 Fahrenheit degrees per century throughout the four years since Gore launched his mawkish, sci-fi comedy horror B-movie."

Eagle Forum's observer at the Heartland Conference, Pat Carlson of Dallas, reported that its most interesting speaker was Czech Republic President and rotating President of the European Union Vaclav Klaus, who has taken a bold position against the prevailing propaganda about global warming. He described talking to global warming advocates as similar to trying to make "well prepared arguments" using "relevant data" to former East European Communist bureaucrats: "It all fell into emptiness ... they did not listen ... they did not argue back ... they considered you uninformed ... a complainer."

Klaus has written a book called "Blue Planet in Green Shackles -- What is Endangered: Climate or Freedom?" He had previously carried his politically incorrect views to the World Economic Forum in Davos, where he reminded the countries promoting the global warming agenda that they "had not fulfilled even the relatively modest Kyoto Protocol obligations."

As a resident of St. Louis, which boasts a world-class zoo noted especially for its bears housed in their natural habitats, I've been concerned because of the many television spots warning that global warming may make polar bears extinct. I can now stop worrying; the Senate's expert on global warming, James Inhofe, R-Okla., has discovered that polar bears are actually more plentiful than they were 40 years ago.

This was confirmed at the Heartland Conference by Ph.D. polar bear biologist Dr. Mitchell Taylor. He said polar bears are definitely not disappearing; their numbers are holding steady at about 24,000.

At the Heartland Conference, the science of global warming was actually discussed and debated. That was very different from the United Nations conferences Carlson previously attended, where global warming caused by humans was accepted as fact without debate.

The advocates of a U.N. treaty to force the United States to reduce our use of energy are extraordinarily shy about debating the science of the issue. We've yet to hear any of them explain or apologize for their hysterical support of the false assumption of the 1960s that millions of people would starve to death in the 1980s because of overpopulation, or of the 1970s theory that global cooling would kill our agriculture.

Christopher Horner's new book, called "Red Hot Lies: How Global Warming Alarmists Use Threats, Fraud and Deception to Keep You Misinformed," gives many, many examples of how they not only refuse to debate, but are malicious against anyone who dares to contradict their view.
