Delegates wait for the plenary session of the 19th conference of the United Nations Framework Convention on Climate Change COP19 in Warsaw on November 22, 2013. The UN climate change conference that is to lay the groundwork for a new pact to prevent global warming, is scheduled to close Friday.

For two weeks, international delegates have been in Warsaw discussing climate change. Today is the last day of the conference, but these meetings — known formally as the 19th session of the Conference of the Parties — haven't produced all that much in terms of results.

For more on just what's been happening at this conference, we're joined by Michael Dorsey, the interim director of energy and the environment at the Joint Center for Political and Economic Studies in Washington, DC.
