Here's what world leaders agreed to — and what they didn't — at the U.N. climate summit:
The U.N. climate summit ended with calls on governments to return next year with tougher pledges to slash greenhouse gas emissions.
Nations made new pledges on methane gas pollution, deforestation, coal financing, as well as a completion of long-awaited rules on carbon trading and a notable U.S.-China deal.
Climate scientists, legal experts and politicians argue the final deal out of Glasgow resulted in incremental progress inadequate to address the climate crisis.
