The U.S. Carbon Cycle Science Program, in consultation with the Carbon Cycle Interagency Working Group (CCIWG), coordinates and facilitates activities relevant to carbon cycle science and climate and global change under the auspices of USGCRP. The CCIWG supports carbon cycle research across the Federal Government and is responsible for defining program goals, setting research priorities, and reviewing the progress of the research programs that contribute to carbon cycle science. As part of the Sustained Assessment process, the CCIWG led and coordinated the production of The Second State of the Carbon Cycle Report, a state-of-the science assessment of the carbon cycle in North America and its connection to climate and society. Fourteen federal agencies and departments coordinate and support CCIWG program activities. CCIWG works closely with other USGCRP Interagency Groups and engages with U.S. and international partners.
