any time you run into some imbecile wanting to tax you to death to stop "global warming", just remember why you can't buy hairspray anymore in aerosol cans. Remember why you have to pay somebody a fortune to work on your car's air conditioner instead of just filling it yourself with freon. Why the Columbia astronauts died when the foam applied to their external fuel tank came off because the aerosol application was outlawed.
Global Cooling is the reason. Those morons wanted to tax us to death in order to sprinkle carbon dust on the poles to RAISE the temperature of the planet.
Human activity may have some teeny affect on temperatures. That's not what this is about. It's about taking your money and controlling your life.
