RealClimate

 "RealClimate" is a commentary site (blog) on climatology. The site's contributors include climate scientists whose goal is to provide a response to developing stories and a context they feel is sometimes missing in mainstream commentary on climate science and climate change. The forum is moderated, and is restricted to scientific topics to avoid discussion of political or economic implications of the science. "RealClimate" was launched on 10 December 2004 by nine climate scientists.
