Journalists might want to remember that there are many major scientific research institutions studying climate change across the many disciplines needed to describe and understand it. Many of these are attached to universities -- but others are consortiums of labs or partnerships between federal and private entities. There are too many to list, but below you will find some of the weightiest. Whenever possible, we have listed contact info for the director and a link to the faculty directory, so you can go straight to the source. A press contact may help if you do not know which expert you want to talk to.
NCAR is perhaps the greatest U.S. climate research institution. It draws not merely post-docs, but prominent researchers from around the U.S. and around the globe.

The Harvard-Smithsonian Center for Astrophysics is located in Cambridge, MA, with telescopes in other places (including space). It is a joint effort of the Harvard College Observatory and the Smithsonian Astrophysical Observatory. Its primary connection to climate is the study of how stars work. While CfA is a fine astrophysics research facility, it includes among some 300 scientists two climate skeptics, Sallie Baliunas  and Willie Soon , who have asserted that solar variability, not greenhouse gases or orbital mechanics, is the dominant cause of climate change. This assertion is at odds with the evidence. Website . Phone: 617-495-7463. Staff Directory . Director: Charles Alcock, (617) 495-7100, email@example.com . Public Affairs Office .

Produced by Oregon Sea Grant at Oregon State University, Communicating Climate Change is a series of taped interviews with leading social scientists on the question of how to communicate about climate change to a broad public. Interviewees as of April 18, 2008, include Anthony Leiserowitz, Susanne Moser, Caron Chess, Baruch Fischhoff and Ed Maibach. While intended for an audience of meteorologists, science journalists, government agency personnel, university outreach specialists, and members of non-governmental organizations, the podcast offers thought-provoking content for lay audiences as well.
