free of ideology???? Yeah, the deniers are "free of ideology". What a laugh. It's also not just CO2. What of the other gases? While CO2 is on the forefront, there are others including some not found in nature, that are even more potent than CO2. They're parroting a line designed to fool the uninitiated in order to further an agenda. To say that the CO2 concentration effect is somehow maxed out, doesn't pass the smell test, IMO. They're fighting hard to equate a percieved lack of openess with bad science. They have to make it a political issue because 99% of the deniers' scientific objections turn out to be total nonsense.
Now I realize that every bit of evidence is on your side and that it is impossible that there was ever any warming that occurred prior to the Industrial Revolution. All of that notwithstanding, how can it be that the warming over the last 2000 years, less than about 1 degree, occurred with about 60% in the first 1000 years and about 40% in the most recent 1000 years?
Also, How is it that we are cooler today than we were, again by about a degree, 8000 years ago?
I hate to keep quoting Einstein because he was obviously out of step with real scientists, but he said something along the lines of no matter how beautiful the theory, eventually the results must be examined.
