The United Nations climate talks were seen as a stepping stone toward a new climate treaty. Instead, the countries attending have agreed to extend the Kyoto Protocol through 2020.

Weekend Edition Saturday host Scott Simon talks with David Milarch of the Archangel Ancient Tree Archive about their project to plant clones of ancients tree on the Oregon coast.

United Nations climate talks ran into overtime on Friday night, as diplomats pressed for whatever small advantage they could achieve.

As usual, the talks, which are being held in Doha, Qatar, involve closely interwoven issues. They include the usual wrangling over money, as well as early efforts in a multiyear process that is supposed to result in a new climate treaty.

Part of that involves finding a graceful way to phase out the Kyoto treaty, which has not proved to be a successful strategy for dealing with a warming planet.

Mm-hmm.

LICHTMAN: Earlier this week, NASA announced plans to launch another rover to Mars in the year 2020. And there's some buzz, there's some speculation that this one could have a wheel up on Curiosity. Maybe it wouldn't just analyze samples there but could shift them back to Earth.

FLATOW: You know, I've heard that before.

LICHTMAN: Don't be downer, Ira.
