Make their argument

I found an article, by Leonard Weinstein. In it, he addresses the global warming report by the IPCC, the Intergovernmental Panel on Climate Change. This organization is the U.N.'s group whose job it is to tell the world about the world's climate changes.

Mr. Weinstein points out that the IPCC used models to explain the notion of man-made greenhouse gases (GHG's) causing global warming. He makes the case that these models are either inaccurate or greatly exaggerated. He makes points, based on natural climate processes, to support his argument. And he points out, with evidence, that water vapor, not CO2, is the most significant GHG. And it's naturally occurring.

A short biography of M. Weinstein is at the bottom of the article.

I didn't find the IPCC report he's talking about, but I found a report, very recently written, which covers global warming and says it's very likely man-made CO2 is the cause of observed rising temperatures on the planet. It's called the IPCC Fourth Assessment Report. If you go to this page, and click on "full report", it will appear in pdf.

I think it's interesting that the phrase very likely appears in the IPCC report very often. On page 33, part 1.3, they say observations show that the earth is warming, Weinstein makes the argument that warming has been occurring naturally.

On page 38, in part 2.3, they say a positive feedback exists where water vapor is concerned, not CO2. In that way, it agrees with Weinstein. But they say water vapor is not a GHG that forces climate change.

The IPCC report does try to push the idea that it's man-made CO2 that's causing global warming.

It is an extremely long-winded article. But they go back again and again to their models.

In fairness, I'm pointing out the name of a lead writer on the IPCC article, Lenny Bernstein. You can see some of his history here. At the bottom of the page you can access powerpoint slides to a course he teaches, Energy Myths and Realities.

Also in fairness, I saw the slides, and I have to say they seem scientific in their presentation. There's one that deals with ethanol emissions being more toxic than gasoline. I thought that was significant. But, these seem to be lecture notes. I don't know if he believes this point or if he would disagree with it in his lecture.

But no matter how grounded in science he seems to be, I disagree with the notion of global warming.
