Here at the U.N. climate change summit in Paris, France, negotiators have approved draft text for what they hope will form an accord to curb global carbon emissions by the end of this week. The lengthy document still contains more than 900 square brackets to signify areas of disagreement that still need to be resolved. Contentious issues include financing for developing countries, the precise carbon emission reduction targets, and whether or not the text will outline different responsibilities for developing and developed countries. We’ll have more on the COP21 later in the broadcast.
