Negotiators at the U.N. climate talks in Lima, Peru managed to agree on a compromise deal early Sunday morning, the Associated Press reports, more than 30 hours behind schedule after 10 days of negotiations.

Representatives from more than 190 countries were ultimately able to determine what information should be included in the pledges countries participating in a global pact in Paris next year will submit, although the AP reports that "a rigorous review of the greenhouse gas emissions limits" was rejected.

24 hours before the deadline, negotiators had agreed on only one paragraph of text, The Guardian reported. The underlying dispute, as always, was over how the burden and responsibility of curtailing climate change should be shared, or distributed, between richer and poorer nations. The final draft of the text states that countries participating in the Paris pact recognize "common but differentiated responsibilities and respective capabilities, in light of different national circumstances."

"The text went from weak to weaker to weakest," Sam Smith, chief of climate policy for the environmental group WWF, said. "It's very weak indeed."

If it's this difficult getting everyone ("everyone") to agree that big, rich, industrialized nations that have been pumping greenhouse gases into the atmosphere for decades, or longer—and reaping the economic rewards—might need to shoulder some more of the relative responsibility for helping out island nations being flooded by rising seas, it doesn't look good for Paris, where the idea is to talk about what that would actually mean, in terms of policy.

Also countries are supposed to announce by March what they are going to do to cut emissions after 2020. Hmm.
