Report: Short-lived Pollutants Accelerate Climate Change

Officials from 192 countries meeting in Warsaw, Poland this week are taking steps to craft a United Nations treaty to replace the Kyoto Protocol, the global climate agreement that expired last year. While talks are expected to lead to a new treaty by 2015, a new World Bank report advocates action now. As VOA's Rosanne Skirble reports, it calls for the reduction of shorter-lived pollutants - as a way to slow the pace of climate change and save lives.
