Towards science in support of decision making: characterizing the supply of carbon cycle science

As concern about climate change grows, so does interest in deliberately managing the carbon cycle to reduce atmospheric concentrations of carbon dioxide. Given the scientific and technical nature of knowledge of the carbon cycle, one would expect that carbon science would be directly of use to society in considering this objective. However, carbon science is not currently organized or conducted in such a way that it can be usable to the wide diversity of decision makers who might potentially be involved in managing the carbon cycle. This paper reviews the science policies and actors governing the production or "supply" of carbon cycle science, and suggests alternatives for enabling the supply to better meet demand.
