STEVE INSKEEP, HOST:
Let's report, next, on a surprise agreement on climate change. United Nations climate talks in South Africa were not expected to produce much, but negotiators for many nations did make a deal, one that could lead to a major new climate treaty at the end of the decade. NPR's Richard Harris is in Durban, South Africa covering the story. Hi, Richard.
RICHARD HARRIS, BYLINE: Hi, Steve.
INSKEEP: So what is the agreement?
