Kyoto Protocol on the Line at G8 Summit

With the G8 summit underway, President Bush will tout his own alternative to the Kyoto Protocol: letting individual nations form their own global warming goals, rather than complying with limitations on greenhouse gas emissions, as the protocol requires.

Still, hard limits have their supporters. Greenpeace Global Warming Campaign Director Chris Miller told "Morning Call" that, far from creating economic problems for the U.S., instituting limits will allow the U.S. to protect the environment, lead technological advances toward clean energy, and create jobs.

But Christopher Horner, author of "The Politically Incorrect Guide to Global Warming & Environmentalism," questioned the practicality of Miller's assessment.

Bush recognizes that individual countries want to determine their own course when it comes to emissions limitations, Horner said. "Bush is focusing on the politically feasible," he said.
