Greenland is losing so much ice it's getting taller

With 61 GPS-based (GNSS) measuring stations in Greenland, it is possible to measure how the country rises when the ice cap above melts and release pressure on the bedrock beneath. The scientists are able to distinguish between movements from contemporary climate changes and ancient movements from the last ice age.

The flow of glaciers off the edges of Greenland is causing the landmass to rise like a decompressing mattress.

The uplift of Greenland is a long-term and well-known process. Since the end of the last ice age about 11,700 years ago, the retreat of the ice sheet has taken a weight off of Greenland, allowing its bedrock to rise — a process known as glacial isostatic rebound.
