Abstract

An intriguing mechanism of the Pleistocene glacial-interglacial cycles is the phase locking of internal climate oscillations to external forcings, suggesting the leading role of the natural climate variability in the past climate changes on orbital timescales. Similarly, the millennial-scale variability over the last glacial period may be attributed to unforced climate dynamics. One of the central themes of the climate sciences is to acquire a fundamental understanding of climate feedbacks over a broad range of timescales. The main objective of this thesis is to identify the characteristic natural variability in a fully coupled climate-carbon model from orbital to millennial timescales, and the essential feedback processes contributing to such behaviors, such as the role of the oceanic carbon cycle in the dynamical structures of the warm climates.
