Human Interactions with the Carbon Cycle
- Share to:
The main themes raised in the workshop are summarized in this section; the rest of this report provides more detail on the presentations and discussions. A major theme at the workshop was the increased recognition, particularly among natural scientists working on the U.S. Carbon Cycle Science Plan (CCSP) in the field, of the importance of human activities to the carbon cycle. Comments at the workshop indicated that the CCSP is increasingly interested in human activities for at least three reasons:
• The role of human activities in shaping the terrestrial carbon sink is greater than previously believed. Christopher Field, who heads the CCSP Scientific Steering Committee, stated that the CCSP’s research is address- ing only about a third of the carbon sink in the United States and that the rest must be understood by examining human activities. These activities include land cover transformation, the suppression of fires, a shift from open dumping of waste to land filling, and changes in agricultural management. Understanding of such activities is critical for estimating the future size of the sink.
