ice melt

Greenland holds the world's second largest amount of ice, second only to Antarctica. Ice covers four-fifths of Greenland's surface and reaches depths of almost two miles at its thickest spots. The island's large glaciers get the most attention and are attentively monitored while the smaller glaciers go largely unobserved. But a new study reports that it's actually these small coastal glaciers that are more significant, in terms of melting and contribution to sea level rise, than the larger glaciers.
