Advances in Understanding the Causes, Mechanisms, and Impacts of Quaternary Abrupt Climate Changes and Their Implications for the Future
Session ID#: 251129
Session Description:
Abrupt climate changes have occurred at rates comparable to the ongoing anthropogenic warming throughout the Quaternary. Studies of these events provide critical insights into how the Earth System responds to abrupt shifts in the mean climate, but also reveal the spatiotemporal complexity of Earth System dynamics, the roles of different climate forcings (e.g., meltwater, ice sheets, volcanic emissions, solar radiation, isostatic adjustments, etc.), and the feedback mechanisms associated with these events. This session explores the causes, mechanisms, and impacts of past abrupt climate changes during the Quaternary (e.g., Dansgaard–Oeschger events, Heinrich events, the Younger Dryas, the 8.2 ka event, etc.), and how studies of these events may help us better understand future climate change. We welcome contributions that utilize geological and numerical approaches, including novel proxy data, climate model simulations, data assimilation, and new theoretical frameworks.
