Here's what the Ice Age tells us about future sea level rise

A new study on an ancient ice sheet may hold important clues about our planet's future. The research focuses on the Laurentide Ice Sheet, the massive expanse covering North America during the last Ice Age, which ended about 10,000 years ago. A team of scientists found that small spikes in the temperature of the ocean — not the air — likely caused periods of rapid melting and splintering of the ice.SEE ALSO: This 'GOT' star teamed up with Google to capture Greenland's melting iceTheir
