When arguing with leftists (dolts) you have to remember that they think the federal government is a purely altruistic institution, comprised of individuals without a modicum of self interest and self dealing. I know it's naive and foolish, but it's their sophomoric predisposition and it's unwavering.
Look here, you have a group of people arguing tooth and nail that the net worth of handful of people and corporations is some how in parity with the annual giving of the world's governments to agw research. This is a laughable statement that's beyond correction. You would literally have to start by teaching basic accounting on a message board, which would be like teaching mandarin on a message board, only the person to be taught doesn't want to learn.
Further complicating the incomprehension of the leftist (dolt) is their misunderstanding of science and their complete lack of perspective and scale with respect to AGW, specifically the associated consequences of prematurely implementing the policies they want to curtail greenhouse gas emissions. Let's assume AGW is proven one day, but its effects have been overstated by these provably unreliable models by a factor of 50, meaning the effect is essentially de minimus.
They'd nonetheless insist on the economically devastating policies they are proposing, because they are insane and this has nothing to do with science or preserving the earth. It's about power and control. The policies they desire further consolidate wealth within governments, and to the detriment of an ever expanding group of poor people and some rich people that decided to invest in oil instead of green energy.
