The Earth’s climate system consists of several subsystems, oceans, atmosphere, cryosphere, biosphere, and lithosphere, each with its own temporal and spatial scales of variability. Much of the variability across time scales of the climate system originates from the interaction of these subsystems and their internal system dynamics. This session focuses on interactions and feedback mechanisms between the subsystems, as inferred from paleoceanographic reconstructions and modeling.
For this session, we invite contributions from both reconstructions and modeling, which shed light on the origin of climate variability on millennial, orbital, and tectonic time scales. A particular focus will be on past warm intervals, where feedback mechanisms different from today may affect the climate response to forcings such as changing greenhouse gas concentrations and continental configurations. Other foci include the rate of polar ice growth and decay and the ocean’s role in ice sheet dynamics.
