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]
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 Greenland ice sheet is 3 kilometers (1.9 mi) thick and broad enough to blanket an area the size of Mexico.The ice is so massive that its weight presses the bedrock of Greenland below sea level and is so all-concealing that not until recently did scientists discover Greenland's Grand Canyon or the possibility that Greenland might actually be three islands.
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.
The research suggests the critical threshold for the Greenland ice sheet is between 1.7 and 2.3 degrees C of global warming. Bochow said humanity would have 100 years — perhaps more — to cool ...

The Greenland ice sheet has lost about 1,965 square miles to glacial retreat since 1985, a new study says.
In Greenland, two kinds of settled areas are distinguished: illoqarfik (Greenlandic for 'town'; by in Danish) and nunaqarfik (Greenlandic for 'settlement'; bygd in Danish). The difference between the two decreased since the new administrative units were introduced in 2009, with the influence of previous municipality centers decreasing.
