Tropical Terrestrial Perspectives On The Last Glacial Termination

Session ID#: 25682

Session Description:
Comprising almost half the Earth's surface, the tropics are the principal source of energy and water vapor for the climate system and feature increasingly in both conceptual and computer models as a dynamic component of modern and future global climate change. As such, the need for robust data constraining how the tropical system responds to various forcing mechanisms is greater than ever.  This session introduces new terrestrial records of tropical climate, which have tended to lag marine data in both spatial and temporal resolution, and explores the unique vantage of land-based proxies for establishing the bounds of natural climate variability. Our focus is the last glacial termination (~20-11 kyr), the highest-magnitude climate event of the last ~100 kyr and an unparalleled laboratory for examining patterns of abrupt and long-term tropical change. We welcome paleoclimate data from a diverse array of terrestrial proxies trained upon part or all of this period.
