Summary

ENCORE Water is essential for life – that we know. But the honeycomb lattice that forms when you chill it to zero degrees Celsius is also inexorably intertwined with life. Ice is more than a repository for water that would otherwise raise sea levels. It’s part of Earth’s cooling system, a barrier preventing decaying organic matter from releasing methane gas, and a vault entombing ancient bacteria and other microbes. From the Arctic to the Antarctic, global ice is disappearing. Find out what’s at stake as atmospheric CO2 threatens frozen H2O. Guests: Peter Wadhams- Emeritus Professor of Ocean Physics at Cambridge University in the U.K. and the author of A Farewell to Ice: A Report from the Arctic Eric Rignot- Earth systems scientist, University of California, Irvine, senior research scientist, NASA Jet Propulsion Laboratory Åsmund Asdal- Biologist, Nordic Genetic Resource Center, coordinator for operations and management of the Svalbard Global Seed Vault, Svalbard, Norway John Priscu- Polar biologist, Montana State University Learn more about your ad choices.
