PP44A:
An Integrated View of Earth System Dynamics and Interhemispheric Linkages from Decadal to Tectonic Scales II


Session ID#: 10836

Session Description:
Climate variability and change across the earth's history is governed by several key processes that apply across a wide range of timescales, from decadal through orbital to tectonic. These include response to changes in the earth's energy budget, changes in pathways such as ocean gateways, and nonlinearities such as the icecap instability. We seek contributions that consider climate change across timescales to identify key mechanisms for past climate changes. Examples include Arctic amplification of warming or cooling; role of volcanism throughout earth's climate history; role of heat transport across the hemispheres by ocean overturning circulation; evidence for ice-sheet, climate and earth system sensitivity; and the role of continental configuration.
