AB: Over the past few centuries, concentrations of carbon dioxide and other greenhouse gases have increased in the atmosphere, leading to potential changes in climate. Concern has risen such that societies are now contemplating actions designed to mitigate or prevent further increases. A variety of approaches has been suggested: direct reduction of emissions, deliberate manipulation of the natural carbon cycle to enhance sequestration, and capture and isolation of carbon from fossil fuel use. Policy development to date has laid out some of the principles to which carbon management should adhere, including quantification and verification, additionality and separation, permanence, and environmental acceptability. Much of this policy is still being debated, however, and many of the issues involve significant scientific and technological challenges. This presentation will summarize these carbon management principles, and briefly review examples of the scientific knowledge base available to support specific application of policy options. The issues of scaling of observations and mechanistic understanding of the carbon cycle in North America will be emphasized.
