WARSAW (Reuters) - U.N. Secretary-General Ban Ki-moon urged world leaders on Thursday to make "bold pledges" for cuts in greenhouse gases by next September to guide a deal to fight climate change but acknowledged that many nations would be late.
Ban also told Reuters that rich nations' promises at U.N. climate talks in Warsaw for new funds to help the poor tackle more heatwaves, floods and rising sea levels caused by global warming were "insufficient".
