I really didn't have the ambition to fisk this entire series (there seem to be some big assumptions in the carbon isotope analysis). But at least, after a very long time of being derided by making the exact same point about cause and effect between temperature and CO2, apparently it's been elevated into the Conventional Wisdom.

I also notice an almost obsessive attempt to push water vapor off the table. Most global warming articles call CO2 as the most influential greenhouse gas after water vapor, but I can't remember the last time one of those articles showed by how much.

Water vapor also increases as temperature does, but seems to be largely overlooked. Global warming skeptics often quote a figure of "95 percent" as the amount of the overall greenhouse effect of water vapor. So far, my own researches indicate a more plausible number is somewhere between about two-thirds and three-quarters. Still, it's not insignificant.
