Keep him from traveling

Per Al Gore

The former vice president, who earlier urged the countries to speed up the timetable for reducing emissions by two years, said he was optimistic about tougher measures partly because growing public awareness of global warming was spurring "the world's first people power movement" on climate change.

He said that could force political leaders to take action.

"They have to find some courage to resist the special interests, the special fears, the concern that often have wider influences than they should and instead respect the demands of the human future," Gore said.

This year's Nobel Peace Prize is part of that process, Gore said, because it "has already caused increased attention to the problem of moving along to solve the crisis of climate."

Pachauri warned that, in his opinion, data coming in after the panel concluded work on its latest assessment suggests that "the future could very well be far more dire than we believe it is today."

He said the world cannot hope that technology alone will counter the threat, but that people must be prepared to change to way they live.

If governments are serious about ending global warming, they'll start with banning all of Al Gore's travel.
