U.N. Secretary-General Ban Ki-moon has urged governments to put forth more ambitious plans to cut carbon emissions, saying "current pledges are simply inadequate." Speaking Tuesday to a U.N. climate conference in Warsaw, Ban said countries need to "set the bar higher" as they negotiate a new global climate agreement that is supposed to be adopted in 2015. According to AP, he asked countries to bring announcements on climate action to a special summit of world leaders in New York next September. Warning that people around the world now "face and fear the wrath of a warming climate," Ban urged delegates in Warsaw to think about their legacy: "Plan not only for your country, but for your neighbor and your neighbor's neighbor." The two-week conference is set to end Friday.
