UN climate talks near end without timeline for next step: announcing emissions targets

U.N. climate talks are likely to run overtime with more than 190 countries arguing over the building blocks for a new pact to slow global warming.

A draft text presented Friday, the last scheduled day of the two-week conference in Warsaw, gave only vague direction on when countries should present their targets for restricting carbon emissions. That's a key element of the deal that's supposed to be adopted in Paris in 2015.

Despite a push by the European Union and the U.S. for a clear timeline for announcing emissions targets, the draft text only said that commitments should be presented "well in advance" of the Paris summit.

U.S. climate envoy Todd Stern called for "stronger language" to drive the work forward.
