The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick and over 3 km (1.9 mi) thick at its maximum. [ 2 ] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N , near ...

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 freshwater coming from the glacier can slow critical ocean circulation, and the Greenland ice sheet is losing about 270 billion tons of ice mass every year.
During winter, the ice sheet takes on a strikingly clear blue/green color. During summer, the top layer of ice melts leaving pockets of air in the ice that makes it look white. Positioned in the Arctic, the Greenland ice sheet is especially vulnerable to global warming. Arctic climate is now rapidly warming.
The Greenland Ice Sheet lost 5,091 sq km (1930 sq miles) of area between 1985 and 2022, according to a study in the journal Nature published on Wednesday, the first full ice-sheet wide estimate of ...
In the 2010s, the Greenland ice sheet melted at its fastest rate during at least the past 12,000 years, and is on track to exceed that later in the century. [108] In 2012, 2019 and 2021, so-called "massive melting events" occurred, when practically the entire surface of the ice sheet was melting and no accumulation took place.
