Past Climate Change in Earth’s Polar Regions: Lessons for the Future

Session ID#: 158285

Session Description:
Earth’s polar regions are changing rapidly, with profound implications for natural and human systems alike. Predicting how the polar regions will respond to future warming is crucial for robust climate adaptation and mitigation. These predictions depend on understanding how the Arctic and Antarctic regions have responded to past periods of warming and other climate change. We invite submissions of proxy and modeling studies that assess the magnitude, timing, rate and causes of past climate and environmental changes in polar and subpolar regions. Impacts of past climate changes on the polar cryosphere and ecosystems are also of strong interest, with an eye towards forecasting the impacts of future global change. Studies may address a wide range of timescales from orbital to decadal. We also welcome submissions that compare recent observations or model simulations with paleoclimate records or that advance methods for reconstructing polar paleoclimate.
