** FILE ** Then-Vice President Al Gore, center, shakes hands with Japanese Prime Minister Ryutaro Hashimoto, right, as Japanese Foreign Minister Keizo Ouchi looks on prior to their talks in Kyoto, western Japan, in this December 8, 1997, file photo. The American vice president was an environmentalist and the U.S. Congress was conservative. China and India were on the fringes of the climate change debate. And big business said going green would strangle industry. The Kyoto global warming pact, signed 10 years ago on Tuesday, was brokered under vastly different circumstances from those facing negotiators at a U.N. climate conference this week in Bali as they map out the agenda for a successor agreement.
