The National Association of Evangelicals is circulating a draft statement that would endorse mandatory carbon-dioxide emissions limits like those of the Kyoto Protocol in an effort to mitigate or prevent global warming. As someone who has read the science on this debate carefully and widely for about fifteen years, I conclude that there is not adequate scientific evidence to support the notion that such a policy would be of any use in mitigating or preventing global warming, even if its assumption that human energy use is a significant causal factor (and the evidence for that is slim to insignificant). The costs of it in prevented economic development, though, are huge, since energy is one of the most fundamental elements of production. The consequence of such a policy for poor, developing nations would be to slow their development and thus prolong for many years more than would otherwise be the case the severe poverty and attendant disease and early death to which roughly four billion of the world's people are subject.
