PC24B:
The Ocean as a Mediator of Climate and Climate Change II Posters


Session ID#: 28178

Session Description:
The ocean plays a key role in shaping Earth’s climate on timescales spanning seasons to millennia. As the largest reservoir of heat and carbon in the climate system, the ocean is critical for seasonal to decadal climate prediction, projecting climate change over the coming centuries, and making sense of the paleoclimate record. The evolution of climate over the next decade depends sensitively on the state of the ocean today and its coupling to the atmosphere. Earth’s response to greenhouse gas forcing over the 21st century hinges on how heat and carbon are taken up and stored by the ocean. And the climate of the Last Glacial Maximum is thought to have been associated with an ocean circulation that is substantially different from today’s. Understanding and accurately predicting climate at all timescales requires realistic representations of how the ocean exchanges energy, momentum, freshwater, and carbon with the other components of the climate system. This session aims to explore large-scale ocean interactions with the atmosphere, cryosphere, and biosphere in both observations and models of varying complexity. We welcome contributions from studies that examine how the ocean mediates the mean climate, climate variability, and climate change in the past, present, and future.
