     If international leaders were as united as the scientific community on climate change, global warming might

be a thing of the past. "The world's scientists have spoken clearly and with one voice," UN Secretary General

Ban Ki Moon said, "I expect the world's policymakers to act the same."

     Unfortunately, the global political community is a long way from speaking with one voice on anything, and

climate change is no exception. We'll know for sure next week,when environment and energy ministers from

around the world meet on the Indonesian island of Bali for the UN's climate change conference. The summit

(首脑会议) has been held nearly every year since 1992, when the UNFCCC (《联合国气候变化框架公约》)-

the document that has since guided international work on global warming-was agreed on. It was at the 1997

conference that the Kyoto Protocol was passed, but since then, there has been little progress.

     This year's talks will be the most important international environmental discussions in over a decade. The

Kyoto Protoco-which requires developed nations who have agreed on the solution to cut their greenhouse gas

emissions (排放) to about 5% below their 1990 levels by 2012-comes to an end in just five years. The world

needs to begin immediately at Bali the process of preparing another document like Kyoto to be ready by the

end of 2012. Otherwise, we'll be faced with a global vacuum (真空状态), just at the very moment when

greenhouse emissions must begin falling in order to avoid dangerous climate change.

     The good news is that, just last week,150 top global corporations approved a request calling for necessary

cuts in greenhouse gas emissions, a business position that was unthinkable just a year ago. Australia-a Kyoto

holdout, like the U.S.-has just elected a new prime minister with a strong environmental record who says he'll

support the protocol. The U.S. Congress and representatives have also stepped in and taken their own steps

on climate change.

     "There is a building sense that enough time has been wasted and that it is time to act," said Jennifer

Haverkamp, international counsel for Environmental Defense.
