First thing, it is the rare politician that actually cares.

So, if the climate change castrophists were actually correct, and the world ends in fire in 10 years, those politicians wouldn't do anything inconvenient.

But they will do things that make them look good in all the other rich people's eyes. Have to have the expensive car, and arrive on the private jet. If you fall on hard times and can only afford a Cadillac, you are just forgotten by that crowd.

Second thing, a single volcano produces more CO2 than all of humanity.
Further, CO2 doesn't affect temperature. (Al Gore proved this)
And the plants could really use some more CO2 in the atmosphere.

So, instantly we can see that those politicians just want something to tax.
The more they tax, the more money they get.

I wouldn't call those congress-critters hypocrites, they are pure evil.
(if only they were just hypocrites)
