Big Picture Science for July 16, 2018 - On Thin Ice













Big Picture Science - On Thin Ice

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, Irving, 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
