Frustrated negotiators hoped for a last-minute breakthrough Friday as they wrap up a fraught round of UN talks in Germany to forge a climate rescue pact to be adopted by the world’s nations in December. Diplomats have lamented the “snail’s pace” of this week’s haggle in Bonn, accusing one another of rehashing well-rehearsed positions and holding up the real work of line-by-line text bartering. Friday was the sixth-to-last negotiating day, with five more to follow in October, before the highly-anticipated November 30-December 11 UN conference opens in Paris in the presence of heads of state.–AFP
