Zircon crystals reveal onset of plate tectonics
(Phys.org) -- We're familiar with the theory that the Earth's crust is composed of tectonic plates that move, sometimes dramatically to create earthquakes and tsunamis - but until recently, nobody knew how ...

Greenland's current loss of ice mass
The Greenland ice sheet continues to lose mass and thus contributes at about 0.7 millimeters per year to the currently observed sea level change of about 3 mm per year. This trend increases each year by a further 0.07 millimeters ...

Increasing speed of Greenland glaciers gives new insight for rising sea level
Changes in the speed that ice travels in more than 200 outlet glaciers indicates that Greenland's contribution to rising sea level in the 21st century might be significantly less than the upper limits some ...

Greenland may be slip-sliding away due to surface lake melt: study
Like snow sliding off a roof on a sunny day, the Greenland Ice Sheet may be sliding faster into the ocean due to massive releases of meltwater from surface lakes, according to a new study by the University ...

Greenland
Greenland (Danish: Grønland; Kalaallisut: Kalaallit Nunaat, meaning "Land of the people" ) is an autonomous country within the Kingdom of Denmark located between the Arctic and Atlantic Oceans, east of the Canadian Arctic Archipelago. Though physiographically a part of the continent of North America, Greenland has been politically associated with Europe (specifically Denmark) since the 18th century.
In 1979, Denmark granted home rule to Greenland, with a relationship known in Danish as Rigsfællesskabet, and in 2008 Greenland voted to transfer more competencies to the local government. This became effective the following year, with the Danish royal government remaining in charge only of foreign affairs, security and financial policy, and providing a subsidy of Dkr3.4 billion ($633m), or approximately US$11,300 per Greenlander, annually.
Greenland is, by area, the world's largest island that is not a continent in its own right, as well as the least densely populated country in the world. However, since the 1950s, scientists have hypothesized that the ice cap covering the country may actually conceal three separate island land masses that have been bridged by glacier.
