Obama: climate agreement a breakthrough in action

US President Barack Obama called the climate agreement a breakthrough in action. But he said more still needs be done to combat global warming.

Barack Obama, US President, said, "Going forward we're going to have to build on the momentum that we established in Copenhagen to ensure that international action to significantly reduce emissions is sustained and sufficient over time. At home, that means continuing our efforts to build a clean energy economy that has the potential to create millions of new jobs and new industries. And it means passing legislation that will create the incentives necessary to spark this clean energy revolution."
