U.N.'s Ban Seeks Bold Climate Pledges at 2014 Summit; Not a Deadline

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".

Ban will host a one-day summit in New York on September 23, 2014.  Many developing nations want it to be a deadline for rich countries to outline planned cuts in greenhouse gases beyond 2020 as a key step towards a global climate deal in 2015.
