Re: False premise leads to false results
"You really need to educate yourself on the total GHG effect in the atmosphere versus the delta of human GHG emissions."
Yes, done that in much detail. The impact of human emissions of CO2 are well known, anyway. e.g. long term warming of the planet.
"Thermogeddon is not going to happen."
Depends what you mean by 'Thermogeddon'. The planet is likely going to continue getting warmer as a direct consequence of increased level of human caused CO2 emissions. A catastrophic runaway impact as I would infer from your term is apparently quite possible. For instance what happens when the permafrost melts? Or the clathrates?
See http://www.wunderground.com/resources/climate/melting_permafrost.asp
and https://en.wikipedia.org/wiki/Clathrate_gun_hypothesis
"What is more likely to happen is that idiot governments will listen to idiot pseudo-scientists "
Seems to be a particularly American thing, but yes there is apparently a risk of ignoring the problem - largely driven by a massive funding effort by those with vested interested (like fossil fuel companies) to create the illusion of an on-going scientific debate where none really exists.
