...If you establish that the Earth is warming, it doesn't necessarily follow that we have a moral duty to reduce emissions. What should follow is an informed debate about the costs and benefits of various policies to address that warming - reducing emissions is just one possible answer. Another debate should focus on those policies' economic costs.
Al Gore doesn't want to have those debates, because the majority of evidence suggests that emissions reduction will be very costly and will have little effect. Kyoto, fully enacted by all its parties, would for all its cost reduce global warming by a mere 0.07 degrees Celsius by 2050 - a barely detectable amount.
Meanwhile, 2 billion people around the world go without electricity. About 3 million die each year because of fumes given off by primitive stoves. The U.S. economy sneezes when gasoline hits $3 a gallon.
If we have a moral duty, it's to keep energy affordable here and to expand access to it overseas. That's the real moral truth, however inconvenient for Al Gore.
