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.
