quoting from The latest personal attack on Gore

"Al Gore uses a lot of electricity. Al Gore buys carbon offsets. Libertarians who take anthropogenic global warming seriously - count me among them - generally favor markets in emissions over hard regulatory targets for individual homes and businesses. That way people and companies can decide to conserve or offset or buy unused capacity as they see fit, minimizing emissions while maximizing utility.
Curiously, the "free market" think tank that gives us our first link declares that Gore's free choice to use his own money to offset his family's carbon output makes him a "hypocrite," since he thinks global warming is bad. This may seem odd, but perusing the Hit & Run comment thread from which I got the above links will clarify: libertarians believe in principles, and one of the most important principles is
AL GORE SUCKS AND IS FAT FAT FAT!!!!
Therefore anything he does is wrong."
