That is an utterly political tract. You should read the most recent IPCC report. That is the "best guess" among leading climatologists and other scientists. CO2 is up to about 387ppm in the atmosphere as of about 2 years ago, and has been climbing rapidly especially since 1970. It started its most recent climb in the 19th century, as use of fossil fuels became more prevalant, and has increase faster pretty much proportionately with their greater use.

Of course, one thing the skeptics have is this: the scientists who believe the global warming thesis believe that 450ppm is an important number. Once it is meaningfully passed--especially if it lasts for more than a brief period--all mammals and many other life forms on earth will have a hard time adjusting. Especially if this happens as quickly as the rise of the past 30 years (and if nothing is done, the slope will most likely actually be steeper than the past 30 years). Does anyone know this absolutely certainty? Well, as far as I know, the knowledge isn't like the sun will "rise" tomorrow. But it is a good guess, an informed guess.

You can keep dissing the research as much as you want. But as with Iraq, just repeating that something will or won't happen doesn't make it happen. I would have thought you might have learned that by now. But guess not.
