In general, these issues revolve around basic concerns such as: how the various climate components have changed in space and time, and what mechanisms drive the changes; the interactions and feedbacks among the various atmospheric constituents, radiative forcing, and surface boundary conditions, and how they influence dec-cen climate variability and change; how the sources and sinks of greenhouse trace gases and the partitioning of carbon between reservoirs vary on dec-cen time scales, and what mechanisms drive their variations; and identifying the externally forced, internally forced, and coupled modes of variability and change in the Earth's climate system, and the processes and mechanisms driving them. RECOMMENDATION The Dec-Cen panel recommends that the United States initiate a Dec-Cen Program designed to increase understanding of climate variability on decade-to-century time scales, and determine its predictability.

By more clearly delineating the actual nature of decadal variability in the climate system, the capability for detecting anthropogenic climate change will be improved, thereby making an important contribution to the IPCC's goals. The observing system can be built incrementally, but must be initiated immediately, because a long, sustained climate record is required to document the wide range of climate variability and change over dec-cen time scales.
