This is SCIENCE FRIDAY. I'm Ira Flatow. Those of us of a certain age can remember exactly what we were doing on a Friday this hour 50 years ago when we heard the news.

"We think of it as the best thing in the world," says organic farmer Jim Crawford, "and they think of it as toxic and nasty and disgusting."
NPR's Richard Harris has covered the U.N. climate talks since the first treaty was negotiated in Rio de Janeiro in 1992. He's monitoring these new talks, and he joins us now to talk about this long-running argument over climate-related funding for the developing world. Richard, thanks for being here.
RICHARD HARRIS, BYLINE: My pleasure.
