Unfortunately, we are all going to stop laughing when you can't buy incandescent bulbs in a couple years, Interstate highway speed limits are lowered to 50 mph, CAFE averages are raised to 50 mpg and you can't buy any more SUVs, your office is at 82 in the summer and 65 in the winter, carbon taxes raise your gasoline to $8 / gallon, you have to pay $15/day to park in your company parking lot and cement and concrete are hit with a huge CO2 tax to boot, raising everybody's building costs (CaCO3 + Heat --> CaO + CO2). Yeah, that's all real funny.
If we realists don't get organized soon to stop the global panic, all this and more is going to be real within our lifetimes.
I used to think another revolution was impossible. But, the more I see of the insanity of our politicians, I am begging to think we will once again have to fight for our Liberties. If the likes of Gore or any leftist gets power, rough times will lay ahead. This joke that is AGW may turn into a nightmare.
