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

Contribution of the Greenland Ice Sheet to sea level over the next millennium. [PDF]

Sci Adv, 2019
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 ...

A temperate former West Antarctic ice sheet suggested by an extensive zone of bed channels [PDF]

, 2014
Several recent studies predict that the West Antarctic Ice Sheet will become increasingly unstable under warmer conditions. Insights on such change can be assisted through investigations of the subglacial landscape, which contains imprints of former ice ...

Response of a marine-terminating Greenland outlet glacier to abrupt cooling 8200 and 9300 years ago [PDF]

, 2011
Long-term records of Greenland outlet-glacier change extending beyond the satellite era can inform future predictions of Greenland Ice Sheet behavior. Of particular relevance is elucidating the Greenland Ice Sheet's response to decadal- and centennial ...

Paleo sea-level indicators and proxies from Greenland in the GAPSLIP database and comparison with modelled sea level from the PaleoMIST ice-sheet reconstruction

GEUS Bulletin, 2023
One of the most common ways to assess ice-sheet reconstructions of the past is to evaluate how they impact changes in sea level through glacial isostatic adjustment. PaleoMIST 1.0, a preliminary reconstruction of topography and ice sheets during the past

Greenland Ice Sheet - Higher non-linearity of ice flow significantly reduces estimated basal motion [PDF]

, 2018
In times of warming in polar regions, the prediction of ice sheet discharge is of utmost importance to society, because of its impact on sea level rise. In simulations the flow rate of ice is usually implemented as proportional to the differential stress

Greenland surface air temperature changes from 1981 to 2019 and implications for ice‐sheet melt and mass‐balance change

International Journal of Climatology, 2020
We provide an updated analysis of instrumental Greenland monthly temperature data to 2019, focusing mainly on coastal stations but also analysing ice‐sheet records from Swiss Camp and Summit.

Greenland plateau jets [PDF]

Tellus: Series A, Dynamic Meteorology and Oceanography, 2013
The high ice-covered topography of Greenland represents a significant barrier to atmospheric flow and, as a direct and indirect result, it plays a crucial role in the coupled climate system.

Influence of temperature fluctuations on equilibrium
ice sheet volume [PDF]

The Cryosphere, 2018
Forecasting the future sea level relies on accurate modeling of the response of the Greenland and Antarctic ice sheets to changing temperatures. The surface mass balance (SMB) of the Greenland Ice Sheet (GrIS) has a nonlinear response to warming. Cold

The influence of inter-annual temperature variability on the Greenland Ice Sheet volume

Annals of Glaciology, 2023
The Greenland Ice Sheet has become an increasingly larger contributor to sea level rise in the past two decades and is projected to continue to lose mass.
