Challenges for the U.N. Summit
An article by Berkeley Visiting Scholar Rob Collier in the April 2, 2009, San Francisco Chronicle ("Can Obama lay ground for climate talks?") raises interesting questions about some of the more challenging issues facing the participants in the December 2009 U.N. Summit.
Berkeley graduate student researcher Stacy C. Jackson makes the compelling argument that two distinct treaties are needed in Copenhagen at the U.N. Climate Change Summit to separately address the mitigation of long-lived versus short- and medium-lived pollutants. This conclusion results from her analysis of the contributors (pollutants & activities) to climate forcing over a 20-year period.
Her conclusions have been published in Science Magazine and may be read at Science.
