Some specialists are calling for an overhaul of the UN global warming process, which yielded only modest progress in Copenhagen.
Participants approved a Copenhagen accord that sets out emissions-control objectives, sets a target of less than 2 degrees for global warming, and pledges $30 billion in aid to developing countries. The pact is not legally binding.
Negotiations on a deal to curb greenhouse gas emissions and head off global warming were suspended Monday morning in Copenhagen, with poorer countries charging wealthier nations aren't prepared to make necessary cuts in CO2 emissions.
After the first week of global warming talks in Copenhagen, disagreements between nations are still evident, particularly between industrial heavyweights the US and China.
