Audio: In Bali talks, a cheer for Australia

Now that Australia has agreed to ratify Kyoto, the United States remains the only developed country not to have signed on.

When Australia's new Prime Minister, Kevin Rudd, announced to UN conference on climate change in Bali that the first official act of his new government would be to begin to ratify the Kyoto Protocol, representatives from the 189 countries gathered there erupted into thunderous applause. Until now, Australia had been the only developed country aside from the United States not to have ratified the protocol.

The protocol mandates that Australia's greenhouse gas emissions not exceed 8 per cent above 1990 levels. Can Australia do it? Reporting from Bali, Peter N. Spotts discusses the implications of Rudd's announcement.
