RealClimate is a commentary site on climate science by working climate scientists for the interested public and journalists. We aim to provide a quick response to developing stories and provide the context sometimes missing in mainstream commentary. The discussion here is mostly restricted to scientific topics and will only rarely get involved in any political or economic implications of the science. All posts are signed by the author(s), except ‘group’ posts which are collective efforts from the whole team. This is a moderated forum.
