Fix environment without U.S., Gore tells climate change summit

NUSA DUA, Indonesia -The Bush administration is the main obstacle to progress in international efforts to fight global warming, but the rest of the world should move on without it, former U.S. vice-president Al Gore said Thursday night during a special appearance at the United Nations climate change summit.

"I am not an official of the United States and I am not bound by the diplomatic niceties," said Gore in an emotional speech to delegates that lasted close to an hour. "So I am going to speak an inconvenient truth: My own country, the United States, is principally responsible for obstructing progress here in Bali. We all know that."
