Big Picture Science Radio Show - On Thin Ice

On Thin IceWater 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.
