I really hate this argument, this drama. Global warming is measurable. It either exists, or it doesn't.
The real controversy is the cause of global warming. Honest scientists argue over this point. At best I can only be a spectator. I don't have any access to the raw data nor to the equipment required to reliably measure whether this cause or that cause directly contributed to global warming. If you don't either, and you have strong feelings one way or the other, I recognize and will respect your faith, and will not argue with you.
That said, I will stipulate that global warming is happening, AND that I am a contributor because; a) I drive an SUV and b) I eat too many beans (creating methane) IF you will stipulate that under no circumstance will one politician anywhere do anything whatsoever to resolve the problem. At best, all their hot air makes it worse.
