Greenland was once much warmer than previously thought, say scientists who have discovered remains of ancient life in lake mud of the region that survived the last ice age. Today, northwest Greenland hovers in the 30s and low 40s Fahrenheit and weathers snowstorms in summer. However, now researchers believe northern Greenland's ice sheet experienced stronger warming than previously thought, which could mean that Greenland is more responsible for that sea-level rise. The climate in northwest Greenland houses the perfect conditions to preserve the sediments within a small lake. "During the last ice age, the ice sheet there was just thin enough, and the atmosphere was just cold enough that the ice sheet froze to the ground instead of melting at its base and sliding," said Jamie McFarlin, a PhD student in Northwestern University.
