CCSP Research Element:
Global Carbon Cycle
Carbon is important as one of the building blocks
for the food and fiber that sustain human populations, as the primary energy
source fueling economies, and as a major contributor to the greenhouse effect
and climate change. Carbon dioxide and methane concentrations have been
increasing in the atmosphere, primarily as a result of human use of fossil fuels
and land.
CCSP-supported research on the global carbon cycle focuses on identifying
potential future changes to atmospheric, terrestrial, and oceanic storage of
carbon, and movement of carbon among those pools. The program also provides the
scientific underpinning for managing carbon sources and sinks. Specific programs
and projects focus on North American and oceanic carbon sources and sinks; the
impact of land-use change and resource management practices on carbon sources
and sinks; projecting future atmospheric carbon dioxide and methane
concentrations and changes in land-based and marine carbon sinks; and the global
distribution of carbon sources and sinks and how they are changing.
Benefits from this research include:
Increased understanding of the sources and sinks for carbon, helping to
evaluate carbon sequestration strategies and alternative response options
Improved confidence in projections of atmospheric concentrations of
carbon-based greenhouse gases.
