Leaders offer little of substance at the latest climate change gathering in New York

 JUST over 70 days to go and there is miserably little progress yet. The outlook for the global summit on climate change to be held in Copenhagen in December is uncertain. The current version of the draft outcome document for the meeting is hundreds of pages long, with thousands of passages in brackets representing points of disagreement. Climate-watchers are steadily lowering their expectations. They had hoped that activities this week in New York, scheduled around the UN General Assembly, might move things forward. So far there is little to cheer.
