Threatened loss of the Greenland ice-sheet [PDF]

Nature, 2004
The Greenland ice-sheet would melt faster in a warmer climate and is likely to be eliminated — except for residual glaciers in the mountains — if the annual average temperature in Greenland increases by more than about 3 °C. This could raise the global average sea-level by 7 metres over a period of 1,000 years or more.

Holocene deceleration of the Greenland Ice Sheet [PDF]

Science, 2016
Keeping a stiff upper layer The interior of the Greenland Ice Sheet is growing thicker, in contrast to the thinning that is occurring at its edges. Why? MacGregor et al. conclude that more snow is accumulating and that the ice in the interior is flowing more slowly than it did thousands of years ago (see ...

Evidence of meltwater retention within the Greenland ice sheet [PDF]

The Cryosphere, 2013
Greenland ice sheet mass losses have increased in recent decades with more than half of these attributed to surface meltwater runoff. However, the magnitudes of englacial storage, firn retention, internal refreezing and other hydrologic processes that ...

The future sea-level contribution of the Greenland ice sheet: a multi-model ensemble study of ISMIP6

The Cryosphere, 2020
. The Greenland ice sheet is one of the largest contributors to global mean sea-level rise today and is expected to continue to lose mass as the Arctic continues to warm.

The Greenland ice sheet and greenhouse warming [PDF]

Palaeogeography, Palaeoclimatology, Palaeoecology, 1991
Increased melting on glaciers and ice sheets and rising sea level are often mentioned as important aspects of the anticipated greenhouse warming of the earth's atmosphere. This paper deals with the sensitivity of Greenland's ice mass budget and presents a tentative projection of the Greenland component of future sea level rise for the next few hundred ...

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]

The Cryosphere, 2013
We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability

Dynamic ice loss from the Greenland Ice Sheet driven by sustained glacier retreat

Communications Earth & Environment, 2020
The Greenland Ice Sheet is losing mass at accelerated rates in the 21st century, making it the largest single contributor to rising sea levels. Faster flow of outlet glaciers has substantially contributed to this loss, with the cause of speedup, and ...

Microbial abundance in surface ice on the Greenland Ice Sheet [PDF]

Frontiers in Microbiology, 2015
Measuring microbial abundance in glacier ice and identifying its controls is essential for a better understanding and quantification of biogeochemical processes in glacial ecosystems. However, cell enumeration of glacier ice samples is challenging due to typically low cell numbers and the presence of interfering mineral particles. We quantified for the

GBaTSv2: a revised synthesis of the likely basal thermal state of the Greenland Ice Sheet [PDF]

The Cryosphere, 2022
The basal thermal state (frozen or thawed) of the Greenland Ice Sheet is under-constrained due to few direct measurements, yet knowledge of this state is becoming increasingly important to interpret modern changes in ice flow. The first synthesis of this

Effect of ice sheet thickness on formation of the Hiawatha impact crater [PDF]

, 2021
The discovery of a large putative impact crater buried beneath Hiawatha Glacier along the margin of the northwestern Greenland Ice Sheet has reinvigorated interest into the nature of large impacts into thick ice masses. This circular structure is relatively shallow and exhibits a small central uplift, whereas a peak-ring morphology is expected.
