Global Warming Treaty Turns 10

"The Kyoto Protocol was signed as a framework agreement in 1997 under which rich industrialised countries would curb emissions of "greenhouse" gases -- carbon pollution from the burning of fossil fuels that scientists say is dangerously affecting Earth's fragile climate system.It took four years to negotiate the Protocol's highly detailed rulebook, but by that time, the United States had quit the process, under a controversial decision by President George W. Bush...The US pullout has deprived Kyoto of support from its biggest carbon polluter and left it perilously short of failing to muster enough support to take effect."
