COPENHAGEN — No legally binding agreement until sometime next year, emissions targets politically acceptable but not in line with what scientists recommend and only enough money to pay for the climate change needs of developing countries until the end of 2012 appear to be the likely results of the U.N. climate conference, officials and NGOs warned over the weekend.

Midway through the conference that was supposed to produce a legally binding framework for greenhouse gas reductions for the 2012-2020 period, some progress has been made on minor technical issues, officials said.

But developed and developing countries remain divided on the big issue of how to cut greenhouse gases by the amount climatologists say is needed to prevent the worst effects of climate change but is also politically acceptable to all.
