    ANNOUNCER: Early this morning Hurricane Katrina slammed into New Orleans.

    AL GORE, FMR VICE PRESIDENT OF THE UNITED STATES: Is it possible that we should prepare against other threats, besides terrorists?

    PAUL GIGOT, HOST: That was a sneak peek at Al Gore's new global warming documentary, "An Inconvenient Truth." The 2000 democratic presidential nominee's movie and accompanying book are set for release later this month.

    But my guest this week says Gore and other global warming alarmists have created a climate of fear, intimidating dissenting scientists into silence on the subject.

    Richard Lindzen is a professor of meteorology at the Massachusetts Institute of Technology.

    Professor Lindzen, welcome.

    RICHARD LINDZEN, PROFESSOR OF METEOROLOGY, MIT: Thank you.

    GIGOT: We keep hearing and reading that all scientists agree about certain things on global warming, that the world is warming, that it's man made, the cause is man made, and that we must act urgently about it.

    You're a meteorologist, what do you think scientists really agree on?

    LINDZEN: I think they agree that we've probably warmed about a half degree centigrade in the last century. I think they agree that carbon dioxide has gone up 30 percent. I think we agree that carbon dioxide would tend to contribute warming.

    But there is no agreement that the warming we've seen is due to man. Moreover, the warming we've seen is much less than we would have expected on the basis of the models that produce alarm.

    GIGOT: If carbon emissions aren't the cause of global warming, what are some of the other possibilities?

    LINDZEN: Well, there are numerous possibilities at the level of a few tenths of the degree that we're seeing, including nothing. That is to say, the earth's climate is forever changing. It's always warming and cooling. And far more in any given locale than it is globally. And you don't need anything to cause it.

    If we understood it precisely I think we'd be in much better shape, but that isn't the case.

    GIGOT: Some of these predictions of global warming of five, six degrees over the next century — obviously we don't know that for a fact because it's ahead of us. They're based on computer models. How accurate are those models?

    LINDZEN: At this point, there's virtually no objective criterion that says that they work. Moreover, I mean, carbon dioxide alone wouldn't cause that. It would only cause about a degree.

    The predictions of a lot more come from the way the models treat clouds. Every modeler I know acknowledges that they do it disastrous job on clouds. So those predictions are based on things that we know are wrong.
