News of a January 31 "teach-in" on more than 1,000 college campuses nationwide strikes me of just one more example of the growing desperation of the environmental movement that has bet its credibility and influence on global warming.

Mark your calendar for any news about a March 2-4 conference in New York that is expected to draw between 400 and 500 global warming skeptics, i.e., scientists, economists, and policy experts. I suspect that print and broadcast journalists will do their best to ignore this event in what is arguably the media capitol of the nation, if not the world.

Organized by the Heartland Institute and co-sponsored by the International Climate Science Coalition, Oregon Institute of Science and Medicine, and the Science & Environmental Policy Project, it should put to rest the very core of the "teach-in", the notion that there is a consensus among the world’s scientists that global warming is happening or about to happen.

In one way, even the Greens are right. There is global warming and the reason is that it is a perfectly natural phenomenon based entirely on the activity of the Sun. No one disputes that the Earth has warmed about one degree Fahrenheit since the end of the last mini-ice age around 1850. And, as Martha Stewart would say, that’s a good thing.
