The U.S. Global Change Research Program is producing a Climate Science Special Report (CSSR), which will inform the content of the fourth National Climate Assessment. The National Academies of Sciences, Engineering, and Medicine is seeking nominations for a new ad hoc Committee that will conduct an independent review of the CSSR, concurrent with the public comment period for the document. The document will be available by early next year.
Nominations are being sought for individuals with expertise in key areas addressed in the CSSR, including but not limited to: climate variability; observed climate change; climate sensitivity and feedback processes; radiative forcing; atmospheric chemistry; ocean acidification and biogeochemistry; climate intervention and mitigation; attribution of climate change; extreme weather events; and climate modeling and projections. 
Additional information and a link to the nomination form is available online. Nominations are due by Friday, October 7.
