because we have primed the natural cycle with unprecedented amounts of CO2.
As for "global warming" being caused by man. It would be more accurate to say that some feel that climate change is being accelerated by man. Some feel that we will push it to unprecedented temperatures.
Another link to a NASA scientist's views on the subject and how it has been treated by the politicians and special interest groups.
Climate Expert Says NASA Tried to Silence Him - New York Times
Page 11 of this next presentation is the chart you want to see. It shows todays green house gases compared to the natural cycle as evidenced by gases found in glacial ice cores.

Dr. James E. Hansen's website has lots of data.
Dr. James E. Hansen Makes interesting reading.
Tig,
Thank you for the links. While I agree that it's interesting reading, I also find it hard to take anything in the New York Times seriously.
I realize that we can go back and forth forever listing scientist after scientist who disagree with each other, and why each other is wrong, without even agreeing on anything. I'm not going to try to explain why they are wrong, in fact, I'm sure they are correct in what they have observed.
The difference is that I have no faith at all in there conclusions. Time after time they have been proven wrong. It's nice to think that we should plan for the worse, but when all the do is predict doom and gloom, and it never happens, then I begin to wonder about their motives.
After Katrina, what was the national news about? All these experts told us how global warming was responsible for the huricane season and that the following year was going to be even worse. Did anybody hear one prediction that turned out to be accurate? How many caought that very short lived story that last years hurricane season wasn't even a record breaker and that the worse seasons were in the 1930's and 1940's?
When the experts can accurately tell me what the weather will be like in the next five days, then I'll listen to what they say will happen in the next fifty years. They just don't have any credibility.
As to CO2 levels, you'll find that a single volcano eruption puts out more than what all mankind has. The planet has a way of dealing with it.
I'm all for clean air, water and land. But some people seem to blur polution and global warming into the same thing. I believe these are two seperate issues. Polution is something that we should all work to eliminate.
