Steve Milloy explains the value:
Last March, the prestigious New York debating society Intelligence Squared sponsored a debate on global warming, which may be viewed here. A pre-debate poll indicated that, by 2-to-1 (57 percent to 29 percent, with 14 percent undecided), the audience believed that manmade global warming was a crisis. But in the post-debate poll, the audience reversed its pre-debate views - the ranks of the skeptics swelled to 46 percent, the believers plummeted to 42 percent and the undecided declined slightly to 12 percent.
"That's the power of debate," said Milloy. "Though Al Gore aggressively promotes global warming alarmism, he unfortunately seems to lack confidence in his ability to debating climate change against others. But Al Gore's curious reluctance will hardly stop the public from being able to see how his points stack up against that of climate experts," Milloy concluded.
