BEIJING (AP) - The United States and China have pledged to take ambitious action to limit greenhouse gases.
At a news conference in Beijing today, President Barack Obama announced that the U.S. would move much faster in cutting its levels of pollution.
Chinese President Xi Jinping (shee jihn-peeng) agreed to cap China's emissions in the future.
