Not all scientists believe that global warming is caused by man, or even that the rise in CO2 from .04% to .02% or whatever is caused primarily by man. The
Great Global Warming Swindle documentary does a pretty good job of debunking this. (a documentary made by Marxists, btw) Solar activity and/or the earth's Malinkovich cycles cause global warming, and global warming in turn causes higher amounts of CO2 to be released from the oceans. If man-made CO2 causes global warming, then you'll have to explain why the temperature of Mars is rising too.
I couldn't care less what some ignoramus politician says, especially when he's wrong about 80% of the time on any given issue, especially when his wall street buddies are licking their chops at the prospect of making profits from trading carbon credits.
Translation: I can't argue facts, so I'm going to pretend that there is a consensus. Scientists would never chase after government grant money, and government has no motivation to push the idea of man-made global warming, no siree. They are interested in our well-being, not carbon credits and sin taxes on energy.
PS: I'm not a neocon, in fact I argue with neocons frequently as my post history shows.
