Accelerating ice flow at the onset of the Northeast Greenland Ice Stream
Deep in the interior of the Greenland ice sheet, ice flow is speeding up — but not due to recent changes in climate.

The Transient Sensitivity of Sea Level Rise
As we warm our planet, oceans expand, ice on land melts, and sea levels rise. On century time scales, we find that the sea level response to warming can be characterized by a single metric: the …

Normalized US hurricane damage estimates using area of total destruction, 1900−2018
We present an approach to normalize hurricane damage, where damage is framed in terms of an equivalent area of total destruction. This has some advantages over customary normalization schemes, and we …

Greenland Monthly Accumulation Maps (1960–2022)
How do you merge and reconcile observations of accumulated snow with regional climate model output from a reanalysis? We propose a way… Abstract Accurate estimates of snow accumulation over the …

Modeled Greenland Ice Sheet evolution constrained by ice-core-derived Holocene elevation histories
Abstract During the Holocene, the Greenland Ice Sheet (GrIS) experienced substantial thinning, with some regions losing up to 600 meters of ice. Ice sheet reconstructions, paleoclimatic records, and …

Failure strength of glacier ice inferred from Greenland crevasses
We uncover a new failure criterion for ice using a large dataset of greenland crevasses. Abstract Ice fractures when subject to stress that exceeds the material failure strength. Previous studies have …

The influence of inter-annual temperature variability on the Greenland Ice Sheet volume
Temperature variability in the forcing of the ice-sheet model affects both the Greenland Ice Sheet equilibrium volume and its transient response to instantaneous changes in temperature. Abstract The …

Modelling fabric structure at Dome C
Simulating higher-order fabric structure in a coupled, anisotropic iceflow model: application to Dome C. Abstract Ice-crystal fabric can induce mechanical anisotropy that significantly affects flow, …

Episodic Subglacial Drainage Cascades Below the Northeast Greenland Ice Stream
The presence of water flowing beneath the Greenland Ice Sheet impacts the friction exerted on ice flowing from inland to marginal regions, potentially affecting the rate of sea level rise by …

Directional hardening of the Northeast Greenland Ice Stream
Crystal orientation fabric anisotropy causes directional hardening of the Northeast Greenland Ice Stream. Abstract The dynamic mass loss of ice sheets constitutes one of the biggest uncertainties in …

The Transient Sea Level response to external forcing in CMIP6 models
The planet is warming, and sea levels are rising as oceans expand and ice on land melts. The warmer the Earth gets, the faster the seas will rise. Projecting future sea level rise (SLR) using …
