Greater Greenland Ice Sheet contribution to global sea level rise in CMIP6 [PDF]
The potential contribution of Greenland Ice Sheet to sea level rise in the future is known to be substantial. Here, the authors undertake new modelling showing that the Greenland Ice Sheet sea level rise contribution is 7.9 cm more using the CMIP6 SSP585

East Greenland ice core dust record reveals timing of Greenland ice sheet advance and retreat [PDF]
Accurate measurements of the past extent of the Greenland ice sheet are crucial to understand its response to changing climate conditions. Here, the authors present a dust record from an ice core from the east coast of Greenland to provide detailed time ...

Overshooting the critical threshold for the Greenland ice sheet. [PDF]
Simulations using two state-of-the-art ice-sheet models show that abrupt melting of the Greenland ice sheet following overshooting of the global mean temperature critical threshold can be mitigated by subsequent cooling to below 1.5 °C.

A first constraint on basal melt-water production of the Greenland ice sheet. [PDF]
The Greenland ice sheet has been one of the largest sources of sea-level rise since the early 2000s. However, basal melt has not been included explicitly in assessments of ice-sheet mass loss so far.

Mineral phosphorus drives glacier algal blooms on the Greenland Ice Sheet. [PDF]
Melting of the Greenland Ice Sheet is a leading cause of land-ice mass loss and cryosphere-attributed sea level rise. Blooms of pigmented glacier ice algae lower ice albedo and accelerate surface melting in the ice sheet’s southwest sector.

Twenty-first century ocean forcing of the Greenland ice sheet for modelling of sea level contribution [PDF]
Changes in ocean temperature and salinity are expected to be an important determinant of the Greenland ice sheet's future sea level contribution. Yet, simulating the impact of these changes in continental-scale ice sheet models remains challenging due to

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

Forty-six years of Greenland Ice Sheet mass balance from 1972 to 2018. [PDF]
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.

Contribution of the Greenland Ice Sheet to sea level over the next millennium. [PDF]
Simulations show that the Greenland Ice Sheet could disappear within a millennium if greenhouse gas emissions continue unabated. The Greenland Ice Sheet holds 7.2 m of sea level equivalent and in recent decades, rising temperatures have led to ...
