Explore cutting-edge research on climate change impacts on cryospheric systems in this 2-hour conference session from the 2012 AGU Fall Meeting. Delve into multiscale drivers of mountain cryosphere changes, quantifying climate shifts using tropical glaciers, and temperature reconstructions from ice caps. Examine late-Pleistocene climate reconstructions, rock glacier responses to warming, equilibrium-line altitudes in cold environments, and deglaciation timing. Gain insights on unprecedented ice cap retreat in Arctic Canada. Access abstracts covering diverse topics from tropical to polar regions to understand the complex interactions between climate and Earth's frozen systems.
