Algal photophysiology drives darkening and melt of the Greenland Ice Sheet. [PDF]

Proc Natl Acad Sci U S A, 2020
Significance Processes that darken the surface of the Greenland Ice Sheet (GrIS) enhance energy absorption and accelerate melt, with consequences for global sea-level rise. Here, we demonstrate how summer blooms of “glacier algae” darken the ice surface,

Possibility of Stabilizing the Greenland Ice Sheet

Earth's Future, 2021
Recent acceleration in the retreat of the Greenland ice sheet under a warming climate has caused unprecedented challenges and threats to coastal communities due to the rising sea level and increasing storm surges.

Design and results of the ice sheet model initialisation initMIP-Greenland: an ISMIP6 intercomparison [PDF]

The Cryosphere, 2018
Earlier large-scale Greenland ice sheet sea-level projections (e.g. those run during the ice2sea and SeaRISE initiatives) have shown that ice sheet initial conditions have a large effect on the projections and give rise to important uncertainties. The

Greenland ice sheet mass balance from 1840 through next week

Earth System Science Data, 2021
. The mass of the Greenland ice sheet is declining as mass gain from snowfall is exceeded by mass loss from surface meltwater runoff, marine-terminating glacier calving and submarine melting, and basal melting. Here we use the input/output (IO) method to

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 ...

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.

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 Chernobyl Reference Horizon (?) in the Greenland Ice Sheet [PDF]

, 1989
Published reports of the presence of radioactive debris from the Chernobyl reactor accident in snow on the Greenland ice sheet raised the strong prospect that such debris might constitute a valuable time stratigraphic marker all over the ice sheet. Large

Missing sea level rise in southeastern Greenland during and since the Little Ice Age [PDF]

Climate of the Past, 2023
The Greenland Ice Sheet has been losing mass at an accelerating rate over the past 2 decades. Understanding ice mass and glacier changes during the preceding several hundred years prior to geodetic measurements is more difficult because evidence of past ...

Forty-six years of Greenland Ice Sheet mass balance from 1972 to 2018

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance We reconstruct the mass balance of the Greenland Ice Sheet for the past 46 years by comparing glacier ice discharge into the ocean with interior accumulation of snowfall from regional atmospheric climate models over 260 drainage basins.
