His conclusion was that it would be more accurate to say that global warming causes increased carbon dioxide, as opposed to the opposite, that increased carbon dioxide contributes to global warming.
Ahem, increased C02 *DOES* increase global warming. How do I know? The CO2 in our atmosphere keeps the global temperature above freezing.
Is too much C02 a bad thing with regards to global warming? Yes, and if you don't believe me, look at Venus, with its surface temperatures hot enough to melt lead. Venus's temperatures are the end product of a process of a runaway greenhouse effect , and you are telling me that increasing CO2 emissions from human activity will not cause an increase in global temperatures?
Perhaps you misunderstood the guy because he could not have been saying what you said he was saying, and still be called a scientist. The theory is full of holes.
Naturally, I'm sure he must have been an oil company flunky.
Tell me his name and I will try to find out.
