Greenland sits atop the Greenland plate, a subplate of the North American Plate. [2] [3] The Greenland craton is made up of some of the oldest rocks on the face of the earth. The Isua greenstone belt in southwestern Greenland contains the oldest known rocks on Earth, dated at 3.7–3.8 billion years old. [4]
Ice core samples from Camp Century were used to create stable isotopes analyses used to develop climate models. [6] [7] [8] Analysis of soil contained in the samples suggests that the site was ice-free as recently as 400,000 years prior, indicating a much reduced Greenland ice sheet and therefore much higher sea levels.

Greenland has been inhabited at intervals over at least the last 4,500 years by circumpolar peoples whose forebears migrated there from what is now Canada. [18] [19] Norsemen settled the uninhabited southern part of Greenland beginning in the 10th century (having previously settled Iceland), and the 13th century saw the arrival of Inuit.
NASA scientists in Greenland took an unprecedented look at Cold War history when surveys found an abandoned "city under the ice.". In April, two scientists surveying the Greenland Ice Sheet found ...
The ancestors of the Greenlandic Inuit who live there today appear to have migrated there later, around the year 1200, from northwestern Greenland. While the Inuit survived in the icy world of the Little Ice Age , the early Norse settlements along the southwestern coast disappeared, leaving the Inuit as the only inhabitants of the island for ...
Like most European nations, Greenland switched over to daylight saving time on March 25, 2023, moving their clocks one hour forward. But they observed the seasonal ritual for the last time.
The geology of Greenland is dominated by crystalline rocks of the Precambrian Shield. [1] The crystalline rocks of the Nuuk/Qeqertarsuatsiaat area comprise some of the oldest bedrock in Greenland which covers most of western Greenland. The surface has been altered several times and has an appearance as though it were shaped billions of years ago.
The Greenland ice sheet has lost about 1,965 square miles to glacial retreat since 1985, a new study says.
