The climate change summit in Copenhagen wrapped up over the weekend - and a muted response has greeted what some are calling a toothless agreement, which observers note is merely a statement of intent rather than a binding document. David Biello, associate editor of environment and energy at Scientific American, was at the summit in Copenhagen. He says if you try to pick winners and losers from the conference you'll find that no nation really came out on top. And Kathleen McGinty, chair of the White House Council on Environmental Quality during the Clinton administration, says that the White House blew an important chance for diplomatic action.
Climate talks in Copenhagen wrap up today, but will an appearance by President Obama inspire nations to strike a last-minute deal? We talk with Kathleen McGinty, former chair of the White House Council of Environmental Quality, and Peter Thomson, the environment editor for PRI's The World, about what to look for as countries try to reach an agreement in the final hours.
