We would like to inform you that the Second State of the Carbon Cycle Report (SOCCR2) was released by the U.S. Global Change Research Program (USGCRP) via https://carbon2018.globalchange.gov. With over 200 contributing experts, this interagency highly influential scientific assessment was led by the Carbon Cycle Interagency Working Group (CCIWG) and U.S. Carbon Cycle Science Program. Individual chapter PDFs can be downloaded HERE. Incorporating 19 chapters distributed across four interconnected sections (I. Synthesis, II. Human Dimensions of the Carbon Cycle, III. State of Air, Land, and Water, IV. Consequences and Ways Forward), SOCCR2 assesses the last decade of cross-sectoral carbon cycle advances across the U.S., Canada and Mexico, in the global context. The global community might also be interested in the 4th U.S. National Climate Assessment which was released simultaneously via https://nca2018.globalchange.gov.
