Day Two of the United Nations Climate Change Conference 2009

The second day of the 15th United Nations Climate Change Conference (UNFCCC) in Copenhagen for a 12-day conference kicked off on a high note with encouraging words from UNFCCC Executive Secretary Yvo de Boer.

He said negotiators must use the first week of the conference to lay the groundwork for adaptation, mitigation, finance, technology, capacity-building and forests. He also expects funding of at least $10 billion a year from now until 2012 to support developing countries.

"America is serious about climate action". That's the conclusion of a useful new report from the Center for American Progress summarizing the impressive recent Executive, Legislative, and international actions by the U.S. Government.

This is profoundly important news in Copenhagen. For the first time, the nation that has contributed the most to the problem -- and the nation that could do the most to accelerate global solutions -- is at the table. We're not quite there with both feet because the U.S. Senate failed to pass a comprehensive clean energy and climate bill in time. But America is showing up for the global effort as never before.

The outcome of the historic United Nations climate change conference under way in Copenhagen will have reverberations for the future of humanity and the planet, UN Secretary-general Ban Ki-moon said here on Tuesday.

"We've come a long way in just two years' time, but what we do now over the next two weeks (in Copenhagen) will determine how we fare," Ban told reporters at the UN Headquarters in New York.

More than 100 heads of state and government, such as U.S. President Barack Obama and Chinese Premier Wen Jiabao, as well as over 15,000 participants, are set to take part in the event in the Danish capital, where nations are expected to wrap up agreement on an ambitious new climate change deal.
