Hydrogen fuel exhaust is water vapor. I wonder what liberals will do when they realize water vapor is a much more effective green house gas than CO2? Probably demand that we import all our hydrogen rather than make it ourselves. And solar cells, they absorb the sun’s heat instead of letting it otherwise reflect back into space. So we’ll need an albedo tax. The government can use the money to research other alternative energies, such as pixie dust that doesn’t harm the environment, and you can even smoke it like marijuana. Surely if a liberal can imagine it, it must exist.
I'm fond of that fact, as well. You must have seen the proposal to put ships in the ocean designed to blow sea water in the air to make clouds to shield us from the sun's rays :-)
Of course, I'm still waiting for an explanation about how CFCs manage to eat only ozone way up in the atmosphere, completely ignoring the ozone at ground level that causes bad-air days :-) (oh, and an explanation about how ice-core samples show flowers used to grow at the North Pole, what caused the glaciers to melt before there were SUVs, etc, etc...)
