I finally saw the Gore movie yesterday. It's thoroughly persuasive about the reality of global warming and the contribution of carbon dioxide emissions to it. I'd recommend it strongly to anyone. Its blindspots were, however, obvious. No mention is made anywhere of the fact that Al Gore was a very powerful vice-president for eight years in a critical period for this issue. His fulminations against others' indifference would have been a little more credible if he'd at least addressed and explained his own failure to do anything when he was able to. It's also striking that Gore could have used the movie to argue for a serious increase in the gas tax - and he didn't. The movie's final recommendations - recycle! write your congressman! ride a bike! reset your thermostat! - were truly lame after the alarm of the rest of the movie. I think a serious gas tax and a tough increase in mandatory fuel economy standards in the U.S. are essential to prompting the technological breakthroughs that alone can ameliorate this. And yet Gore balked. Just like he did when he was in power.
