The second “State of the Carbon Cycle of North America Report” (SOCCR-2) includes an overview of the North American carbon budget and future projections, the consequences of changes to the carbon budget, details of the carbon budget in major terrestrial and aquatic ecosystems(including coastal ocean waters), information about anthropogenic drivers, and implications for policy and carbon management. SOCCR-2 includes new focus areas such as soil carbon, arctic and boreal ecosystems, tribal lands, and greater emphasis on aquatic systems and the role of societal drivers and decision making on the carbon cycle. SOCCR-2 provides information to support science-based management decisions and policies that include climate change mitigation and adaptation in Canada, the United States, and Mexico. Findings indicate that North America is a net emitter of carbon dioxide and methane to the atmosphere, and that natural sinks offset about 43% of emitted carbon dioxide.

With SOCCR-2 providing a baseline about carbon sinks over the last decade, the current role of land ecosystems in removing CO2 from the atmosphere is highlighted, along with research needs to facilitate the important role of negative emissions in reducing greenhouse gases sufficiently to limit climate warming to 2 degrees C or less by the end of this century. Afforestation, improved land management, and bioenergy crops are technologically ready for deployment at large scales to achieve reductions of about 10 PgCO2 per year globally. However, research needs to achieve this involve: how to reduce barriers to deployment and achieve full participation by landowners; new approaches to reduce impacts on biodiversity, water, and other land values; better understanding of induced impacts such as changes in timber markets; and improved monitoring and accounting approaches.
