Carnegie's Anna Michalak spoke with Sierra magazine about an assessment of the carbon stocks and fluxes in soils, water, vegetation, aquatic-terrestrial interfaces, human settlements, agriculture, and forestry. This State of the Carbon Cycle Report was released together with the Fourth National Climate Assessment over Thanksgiving weekend.
"The Second State of the Carbon Cycle Report (SOCCR2) was led and developed by the Carbon Cycle Interagency Working Group (CCIWG) under the auspices of the U.S. Global Change Research Program (USGCRP). Contributing to the Fourth National Climate Assessment (NCA4), SOCCR2 is designed as a special interagency assessment focused on the advances in the science and the understanding of the carbon cycle across North America since the first SOCCR (2007). Specifically, SOCCR2 focuses on U.S. and North American carbon cycle processes, stocks, fluxes, and interactions with global-scale carbon budgets and climate change impacts in managed and unmanaged systems. The report includes an assessment of the carbon stocks and fluxes in soils, water (including near-coastal oceans), vegetation, aquatic-terrestrial interfaces (e.g., coasts, estuaries, wetlands), human settlements, agriculture, and forestry. It considers relevant carbon management science perspectives and science-based tools for supporting and informing decisions, as addressed in and related to A U.S. Carbon Cycle Science Plan (2011) and other documents, such as the USGCRP Strategic Plan (2012-2021) and the Global Change Research Act (1990). The status of and emerging opportunities for improving measurements, observations, and projections of stocks and fluxes in the carbon cycle, including uncertainty identification, are part of the Report."
Michalak was lead author on the 2011 A U.S. Carbon Cycle Science Plan described above, and co-led Chapter 1 of SOCCR2.
