No idea how that guy can be taken seriously. Shorter version: CO2 is not a greenhouse gas because he says so.

I tried to distill the few, um, scientific, arguments in between the spam:

Well, it is simply not happening. Worldwide there was a significant natural warming trend in the 1980’s and 1990’s as a Solar cycle peaked with lots of sunspots and solar flares. That ended in 1998 and now the Sun has gone quiet with fewer and fewer Sun spots, and the global temperatures have gone into decline.

You know you can stop reading as soon as you are told that the earth has cooled since 1998. Anyway, the connection with the sun has been debunked multiple times already.

Earth has cooled for almost ten straight years.

No, it hasn’t.

Let me illustrate. I estimate that this square in front of my face contains 100,000 molecules of atmosphere. Of those 100,000 only 38 are CO2; 38 out of a hundred thousand. That makes it a trace component. Let me ask a key question: how can this tiny trace upset the entire balance of the climate of Earth? It can’t. That’s all there is to it; it can’t.

Not sure what he is trying to say here, all he has demonstrated is his impressive ability to divide by ten. I guess he thinks that because the mixing ratio is small it cannot have a large effect. Which is quite silly, because a lot lower mixing ration of cyanide will have a devastating effect on your body for example. And there a lot more effective toxins. Well, the point is that CO2 is a triatomic gas, which does absorb infrared radiation, while the much more common gases (nitrogen, oxygen and argon) have two or just one atom. That makes a lot of difference. And that’s not just something pulled out of thin air, it can be measured. (Pun not intended, but tolerated).

One point Coleman makes repeatedly is the claim that the only greenhouse gas we are worried would be carbon dioxide, which isn’t quite correct. There are also methane, nitrous oxide and, to a lesser extent, CFCs.

The rest of the article doesn’t contain any scientific arguments. This one certainly isn’t:

I suspect you haven’t heard it because the mass media did not report it, but I am not alone on the no man-made warming side of this issue. On May 20th, a list of the names of over thirty-one thousand scientists who refute global warming was released. Thirty-one thousand of which 9,000 are Ph.ds. Think about that.

Well, I did think about it and found that there are 22,000 scientists without a PhD on that list. Anyway, it seems to be quite easy to get onto that list. And this is not a signature contest in the first place.

Coleman opened his speech with:

You may want to give credit where credit is due to Al Gore and his global warming campaign the next time you fill your car with gasoline, because there is a direct connection between Global Warming and four dollar a gallon gas.

Later he argues:

The battle against fossil fuels has controlled policy in this country for decades. It was the environmentalist’s prime force in blocking any drilling for oil in this country and the blocking the building of any new refineries, as well. So now the shortage they created has sent gasoline prices soaring.

Completely wrong. For example. drilling in the ANWR would decrease the price of gasoline by 2 cents. And the refineries are underutilized. Who cares, when we can have a cheap shot at the evil environmentalists.

If Al Gore and his global warming scare dictates the future policy of our governments, the current economic downturn could indeed become a recession, drift into a depression and our modern civilization could fall into an abyss. And it would largely be a direct result of the global warming frenzy.

Sounds alarmist, doesn’t it?
