Help with a refutation?

[Orrex]

A friend has been complaining on FB about the "global warming controversy." In particular, he's asserted repeatedly that humans are responsible for "one sixth of one percent" of global warming.

He's not usually a flat-earther, but he is a Republican. Surprise surprise!

Obviously he won't give a citation, demanding instead that everyone else prove him wrong. I don't particularly care about proving his foolishness, but I remain kind of curious about it.

Any idea where he came up with that particular figure? He's quoted it often enough for me to think that he must have heard it somewhere.


Thanks!

1. Tell him the only "controversy" is that he refuses to provide a citation for his horseshit stats. nt

2. I'm gonna guess Limbaugh

He is the source of most of the GOP 'arguments' and he just pulls them out of his ass.

That is why Romney kept saying the most absurd stuff, why so many Republicans say off the wall stuff they feel completely confident in but can't back up...because they heard him say it, and they actually believe he tells the truth.

Limbaugh is making fools of them, because they don't know he just makes stuff up. It they ever do find out, you would think they would be mad as hell, particularly with their emotionally reactive tendencies.

3. Smells like he is talking about absolute increase in CO2

Which is about 160 ppm since 1750, which is about a 58% increase or he could be talking about this as the increase in heat trapping due to this increase in CO2. In the last case he is ignoring positive feedback effects and is ignorant of compound interest calculations.

4. Thanks!

I'll keep that in mind.

5. Remember you have to use words they will understand

I would start now by making it clear your refudiating his point
