NEEM ice core reaches Greenland bedrock

Last week, my travel partner to Antarctica, meteorologist Dan Satterfield, traveled to another icy part of the world: Greenland. He's reporting on the North Greenland Eemian Ice Drilling (NEEM) project - the Arctic equivalent of Antarctica's WAIS Divide core. The NEEM ice core will give an accurate account of the Northern Hemisphere's temperature up to 120,000 years ago, before the last ice age. This week, the NEEM team finished drilling the core and reached Greenland's bedrock a mile below the surface.
