BONN, Germany,  (Reuters) – Negotiators from 185  nations end two weeks of talks on a new climate treaty today  with a new blueprint for a pact that omits the most draconian  options for greenhouse gas cuts by 2050.

The streamlined 22-page draft also cuts all references in a  previous text to “Copenhagen”, the host city for a U.N. summit  in December that fell short of a binding deal to slow a rise in  temperatures blamed for heatwaves, floods and rising sea levels.

The May 31-June 11 talks are the biggest since the summit,  trying to get negotiations back on track even though many  delegates say that a legally binding deal is out of reach for  2010 and is more likely in 2011.
The new text, issued shortly before midnight (2200 GMT) yesterday, is meant as a blueprint to guide negotiators to  overcome rifts between rich and poor nations when they reconvene  at a next session in early August in Bonn.

It outlines a goal of cutting world emissions of greenhouse  gases by “at least 50-85 percent from 1990 levels by 2050” and  for developed nations to cut emissions by at least 80-95 percent  from 1990 levels by mid-century.
