haha, I just saw SPidey's article.
It does seem a bit retarded on the surface, but the article doesn't specifically blame Bush for Katrina--the actual creation of the hurricane.
I know subtlety isn't you guy's strong point, and literacy tends to be a passing fancy, but here is the sentence with which you use to misinterpret the article's message
It simply repeats the prevailing scientific opinion--completely undisputed in the world of peer-reviewed science--that current trends are leading towards more extreme wether patters. We very much do know that CO2 is a major factor (especially when it comes to oceanic acidification, not so much atmospheric), and the idea of not controlling our oiutput is, well, completely retarded.
Funny, too, that the article spends time showing how Bush/Cheney and Co. had a very progressive, er, I mean "evil librul!" stance on regulating CO2 and controlling climate change, before some other pigheaded blowhard crony approaching them regarding the disastrous effects their policy would have on their own personal finances.
So, yeah--Bush actually wanted to affect legitimate progress in climate science, until it was explained to him that his investments would be hurt.
