Obama: 'No Time to Waste'

Climate-change talks continued in Copenhagen, with most negotiators expecting to work through the night. Earlier Friday, President Obama urged leaders of 193 countries to accept an agreement, even one that he acknowledged was far from perfect. "We are running short on time, and at this point the question is whether we will move forward together or split apart, whether we prefer posturing to action," Obama said, arguing that all major economies should agree to national actions to reduce emissions and a system of evaluating whether countries are keeping their promises. After the speech, Obama met with China's Wen Jiabao for nearly an hour, a development the White House called a "step forward." The U.S. and China may hold the key to striking an agreement.
