From 2002 to 2009, USGCRP was known as the U.S. Climate Change Science Program (CCSP). CCSP created a series of 21 Synthesis and Assessment Products (SAPs), centered around five scientific goals, that integrated research on key climate science issues and aimed to support informed discussion by decision makers, stakeholders, and the general public.
