Greenland ice sheet - Wikipedia
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 ...

The Greenland Ice Sheet lost 55 ± 35 Gt of mass in 2024, the lowest annual ice loss since 2013. This occurred due to above-average snowfall and below-average melting and despite higher glacier flow rates than the 1991-2020 average.
Ice Sheets Today - National Snow and Ice Data Center
Nov 19, 2024 · Ice Sheets Today offers the latest satellite data and scientific analyses on surface melting of the Greenland Ice Sheet in the Northern Hemisphere and Antarctic Ice Sheet in the Southern Hemisphere. Surface melt on each ice sheet results from a combination of daily weather conditions and the amount of solar energy absorbed by its snow and ice.
Greenland Ice Sheet | Definition, History, Volume, Map, & Facts ...
Dec 25, 2024 · The Greenland Ice Sheet is a single ice sheet or glacier covering about 80 percent of the island of Greenland. It is the largest ice mass in the Northern Hemisphere, globally second in size to only the Antarctic ice mass.
Greenland Ice Sheet - NOAA Arctic
On 26 June 2023, Summit Station reached a temperature of 0.4°C and experienced melt for only the fifth time in its 34-year observational history. The Greenland Ice Sheet (GrIS) is the second-largest contributor of sea-level rise (SLR), after thermal expansion (Zemp et al. 2019).
Greenland Ice Sheet - NOAA Arctic
The Greenland ice sheet covers ~1.63 million km 2 and contains ice equivalent to 7.4 m of eustatic sea level rise (Morlighem et al. 2017). Following decades of relative stability, the ice sheet has now lost mass almost every year since 1998, with tied years of record ice loss in 2012 and 2019 (Mankoff et al. 2021).
An introduction to the Greenland Ice Sheet
May 28, 2024 · The Greenland Ice Sheet is the largest ice mass in the Northern Hemisphere. It lies from 71 ° N northwards, between the Atlantic and the Arctic Ocean [1]. Almost 80% of Greenland’s landmass is covered by the ice sheet, expanding an area over 1.7 million km 2 .
The Ice Sheet – the major attraction of Greenland - [Visit Greenland!]
80% of Greenland’s land area (more than 1.7 million km2) is covered by glacier, called the Greenland Ice Cap or more accurately, the Greenland Ice Sheet. It is one of only two ice sheets in the world, and it has been present for 18 million years.
About the Greenland Ice Sheet - National Snow and Ice Data Center
Nov 21, 2012 · The Greenland Ice Sheet extends about 1.7 million square kilometers (656,000 square miles), covering most of the island of Greenland, three times the size of Texas. Ice sheets contain enormous quantities of frozen water.
Glacier - Greenland, Ice Sheet, Melting | Britannica
Nov 27, 2024 · The Greenland Ice Sheet, though subcontinental in size, is huge compared with other glaciers in the world except that of Antarctica. Greenland is mostly covered by this single large ice sheet (1,730,000 square kilometres), while isolated glaciers and small ice caps totaling between 76,000 and 100,000 square kilometres occur around the periphery ...
