Impact of Ice Sheet-Climate Interactions on Greenland Ice Sheet Mass Balance: Insights from Coupled CESM2-CISM2 Simulations

The Greenland Ice Sheet (GrIS), which stores freshwater equal to more than seven meters of potential sea level rise, strongly interacts with the global, Arctic and North Atlantic climate. In a warming climate, the GrIS has been losing mass and is projected to lose mass at an increasing rate. The interactions between the GrIS and the climate have...

Examination of Drivers of Large Surface Melt on the Greenland Ice Sheet

The Greenland Ice Sheet (GrIS) is an ice sheet situated on the island of Greenland. It has a surface area of about 1.74 million km² and contains a volume of ice equivalent to 7.4 m of global mean sea level rise. The GrIS is vulnerable to climate disruptions such as anthropogenic climate change. As a result of increased greenhouse gas emissions,...

Modelling The Greenland Ice Sheet following The Mid-Eemian: A study of the impact of including lateral variations in the sub-Greenland Earth rheology on the GrIS' evolution since the mid-Eemian in a coupled 3D ice sheet and 3D GIA model

Uncertainty in ice sheet modelling affects centennial and longer time-scale projections of the Greenland Ice Sheet's (GrIS) sea level contribution. One source of this uncertainty is the interaction between the ice sheet’s evolution and the Earth’s deformation in response to changes in the applied surface loading as the ice sheet waxes and wanes....

Connection of future Arctic sea ice retreat with regional climate change and increased melting over Greenland

Today’s climate warming is unequivocal. Evidence from observations and satellite records show that Arctic Ocean is losing its summer sea ice cover with a rapid pace and is dominated by young and thinner ice. The ice loss has already caused heating of the overlying atmosphere. At the same time, the Greenland ice sheet (GIS) surface mass balance...
