Heads up, because old Cogitator will soon show up here espousing how man is changing the climate. Folks like him are as big a problem as the cow fart hypothesis.
Cogitator's biggest problem is he is under the delusion that the science of global warming is not politicized. Cogitator does not see the extreme bias in the reporting.
Man is changing the climate. Even if there was absolutely no fossil fuel CO2 involved, man's activities would change the climate (think about the difference between a plowed agricultural field and a deciduous hardwood forest, for a moment, and then think about what Minnesota used to look like). To think that man's activities have no effect on climate is foolish.
It is customary on here to cc somebody when talking about him.
