The consensus of the noted climate policy scholars whose work is discussed in this article is clear. Given the need to maintain strong US economic growth and address a growing population, a persistent trade deficit, and the retirement of the baby boom generation, policy-makers need to weigh carefully the Kyoto Protocol's negative economic impacts and its failure to engage developing nations in full participation. If growing scientific understanding indicates that such a policy is needed, it is essential to global economic growth and to the stabilization of carbon concentrations in the atmosphere that the US adopt a carefully timed climate change policy. It should be based on accurate science, improved climate models, global participation, tax incentives to accelerate investment in energy efficiency and sequestration, and new technology.
