UN top official calls for unity in tackling climate change

The UN's top climate change official has called on all countries to cooperate and make compromises at the upcoming Copenhagen conference. De Boer, said success at Copenhagen will put the world on a safe, low emissions growth path. He also said the stakes are too high for any country to be focused solely on national agendas.

Yvo De Boer, UN Climate Chief, said, "Rich countries must put at least ten billion dollars a year on the table to kick start immediate action up to 2012 and they must list what each country will provide and how funds will be raised to deliver very large, stable and predictable finance going into the future without constantly have to renegotiate those sums every few years."
