The American Geophysical Union (AGU) is currently accepting abstract submissions for the 2020 Fall Meeting. The meeting will be held online 7-11 December 2020 for concentrated content and 1-17 December to minimize scheduling conflicts.

Conveners of the following session invite abstract submissions:

Session GC046: High-Latitude Earth Systems - Their Local Responses to and Impacts on Global Climate Change
Conveners: Wieslaw Maslowski, Renu Joseph, Milena Veneziani, and Hailong Wang

The polar regions are an integral and unique component of the Earth system, with the cryosphere making them different from other parts of the globe. This distinction complicates the atmosphere-ocean/land coupling, causes high-latitude environments to be exceptionally sensitive to climate change, while teleconnections render polar changes globally and societaly relevant.

This session focuses on progress and challenges in observing and modeling the high-latitude environments, their variability and trends, including results from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) and the Coupled Model Intercomparison Project Phase 6 (CMIP6). Conveners solicit presentations that advance understanding of: (i) the process-level operation of individual components of the polar Earth systems and their coupled interactions, (ii) internal and external drivers of polar climate changes, and (iii) their linkages to lower latitudes and to extreme events. Contributions on reducing model biases and uncertainty in prediction of future polar changes are also invited.

Invited speakers: John E. Walsh (University of Alaska Fairbanks) and Wilbert Weijer (Los Alamos National Lab)
