Toward a real global warming treaty

Last year, the world gathered at Kyoto to grapple with the threat of global warming. But the Kyoto approach-negotiations to set national limits on the emissions of the greenhouse gases that are heating the earth-cannot solve the problem. The emissions targets will never be met without the cooperation of the developing countries, and they will not consent. We would do better to attack global warming through mutually agreed-upon actions, especially a nationally collected tax on greenhouse gas emissions.
