Global warming is a scam. A correlation between x and y in historical survey data does not establish causality because it could mean that x causes y or that y causes x or that a third unobserved variable causes both x and y or even that the correlation is spurious and it does not contain any causality information whatsoever. Causality may only be inferred from controlled laboratory experiments and there has been none. Please don't let the global warming junk science derail your economic stimulus plan. Please take a good unhyped unhysterical cold logic look with that well-wired brain of yours at what the global warming people are saying. It will not make sense. What's worse, they are actually cheering on the economic meltdown because it will lower greenhouse gas emissions. These people are the enemy of your economic revival plan. Please do not trust people who are happy about recession to help you in your efforts to revive the stalled economy.
