The post-Copenhagen climate negotiations seem to be diverging, at least on the question of targets. Brackets, denoting disagreement, have if anything proliferated in the draft texts. The latest from Bonn:
AD HOC WORKING GROUP ON LONG-TERM COOPERATIVE ACTION UNDER THE CONVENTION
Eleventh session Bonn, 2–6 August 2010
Item 3 of the provisional agenda Preparation of an outcome to be presented to the Conference of the Parties for adoption at its sixteenth session to enable full, effective and sustained implementation of the Convention through long-term cooperative action now, up to and beyond 2012
Text to facilitate negotiations among Parties
