New research suggests the Greenland ice sheet is on track to cross a critical threshold that could cause runaway melting, but that it’s also possible the threshold will be crossed temporarily ...
The worst-case scenarios predicted by experts studying Greenland’s ice melt are being outpaced by what’s actually happening, a new study has found. A review of historical data on how glaciers ...
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 ...
Ilulissat Icefjord. The fjord contains the Jacobshavn Isbræ (Greenlandic: Sermeq Kujalleq), the most productive glacier in the Northern Hemisphere.The glacier flows at a rate of 20–35 m (66–115 ft) per day, resulting in around 20 billion tonnes of icebergs calved off and passing out of the fjord every year.
Jakobshavn has the highest mass flux of any glacier draining the Greenland Ice Sheet. The glacier terminus region also had a consistent velocity of 20 metres (66 ft) per day (maximum of 26 metres (85 ft) per day in the glacier center), from season to season and year to year, the glacier seemed to be in balance from 1955 to 1985.

The future development of the ice cap is highly dependent upon summer temperatures. [ 1 ] Hans Tausen Ice Cap ( Danish : Hans Tausens Iskappe ) is an ice cap in Peary Land , northern Greenland .
Daily tides stoked with increasingly warmer water ate a hole taller than the Washington Monument at the bottom of one of Greenland's major glaciers in the last couple years, accelerating the ...
The paper also suggested that ice losses from Greenland may be reversed by reducing temperature to 0.6 °C (1.1 °F) or lower, up until the entirety of South Greenland ice melts, which would cause 1.8 m (6 ft) of sea level rise and prevent any regrowth unless CO 2 concentrations is reduced to 300 ppm. If the entire ice sheet were to melt, it ...
