Authored by more than 200 scientists from the United States, Canada, and Mexico, the Second
State of the Carbon Cycle Report (SOCCR2) provides an up-to-date assessment of scientific
knowledge of the North American carbon cycle. This comprehensive report addresses North American carbon fluxes, sources, and sinks across atmospheric, aquatic, and terrestrial systems,
as well as relevant perspectives from scientific observations and modeling, decision support,
carbon management, and social sciences. The report presents Key Findings and actionable
information on the observed status and trends within the North American carbon cycle, as influenced by natural and human-induced factors. These findings are based on multidisciplinary
research that includes experimental, observational, and modeling studies from the last decade.
Intended for a diverse audience that includes scientists, decision makers in the public and private
sectors, and communities across the United States, North America, and the world, SOCCR2
provides information to inform mitigation and adaptation policies and management decisions
related to the carbon cycle and climate change.
