Yeah let's teach kids that the only way to get anything done is to let big government tax the shit out of us all in the name of saving the planet.
And they won't teach that even if the United States reverted to the fucking stone age that it wouldn't even put a dent in CO2 emissions as long as China India and the rest of the developing world is expanding.
Who said anything about policy response? It was about whether we are warming at all, and if we are, what is the cause.
It has been established beyond doubt that we are warming very rapidly. And established beyond a reasonable doubt that the GHGs that we have introduced into the atmosphere is the primary driver of that warming.
As far as policy response goes, that belongs in Political Science classes.
