The Greenland ice sheet (GrIS) is a growing contributor to global sea-level rise1, with recent ice mass loss dominated by surface meltwater runoff2,3. Satellite observations reveal positive trends in GrIS surface melt extent4, but melt variability, intensity and runoff remain uncertain before the satellite era. Here we present the first continuous, multi-century and observationally constrained record of GrIS surface melt intensity and runoff, revealing that the magnitude of recent GrIS melting… 
Recent Precipitation Decrease Across the Western Greenland Ice Sheet Percolation Zone
Abstract. The mass balance of the Greenland Ice Sheet (GrIS) in a warming climate is of critical interest in the context of future sea level rise. Increased melting in the GrIS percolation zone due
Rapid expansion of Greenland’s low-permeability ice slabs
Observations and regional climate models show that the increasing coverage of ice slabs on the Greenland ice sheet could lead to a global sea-level rise of up to 74 millimetres by 2100.
Greenland Ice Sheet Daily Surface Melt Flux Observed From Space
Greenland Ice Sheet (GrIS) surface melt has contributed to the global sea‐level rise and the ongoing warming is expected to promote this process. This study provides a new strategy for the
Rapid Reconfiguration of the Greenland Ice Sheet Coastal Margin
The Greenland Ice Sheet has lost mass at an accelerating rate over the last two decades, but limits of early remote sensing restricted examination of localized change at an ice‐sheet‐wide scale. We
Greenland Ice Sheet Surface Runoff Projections to 2200 Using Degree-Day Methods
Surface runoff from the Greenland ice sheet (GrIS) has dominated recent ice mass loss and is having significant impacts on sea-level rise under global warming. Here, we used two modified degree-day
Future Evolution of Greenland's Marine‐Terminating Outlet Glaciers
Mass loss from the Greenland ice sheet (GrIS) has increased over the last two decades in response to changes in global climate, motivating the scientific community to question how the GrIS will
Abrupt Common Era hydroclimate shifts drive west Greenland ice cap change
Ice core archives are well suited for reconstructing rapid past climate changes at high latitudes. Despite this, few records currently exist from coastal Greenlandic ice caps due to their remote
Anomalous Circulation in July 2019 Resulting in Mass Loss on the Greenland Ice Sheet
Current mass loss on the Greenland Ice Sheet (GrIS) includes a significant contribution from surface runoff. The circumstances associated with melt events are important for understanding the global
Subglacial lakes and their changing role in a warming climate
Subglacial lakes are repositories of ancient climate conditions, provide habitats for life and modulate ice flow, basal hydrology, biogeochemical fluxes and geomorphic activity. In this Review, we


Ice Core Records of West Greenland Melt and Climate Forcing
Remote sensing observations and climate models indicate that the Greenland Ice Sheet (GrIS) has been losing mass since the late 1990s, mostly due to enhanced surface melting from rising summer
Abrupt shift in the observed runoff from the southwestern Greenland ice sheet
It is found that an abrupt 80% increase in runoff occurring between the 1976–2002 and 2003–2014 periods is due to a shift in atmospheric circulation, with meridional exchange events occurring more frequently over Greenland, establishing the first observation-based connection between ice sheet runoff and climate change.
Climate change and forest fires synergistically drive widespread melt events of the Greenland Ice Sheet
It is found that black carbon from forest fires and rising temperatures combined to cause both of these events, and that continued climate change may result in nearly annual melting of the surface of the GIS by the year 2100.
Clouds enhance Greenland ice sheet meltwater runoff
It is shown that clouds enhance meltwater runoff by about one-third relative to clear skies, using a unique combination of active satellite observations, climate model data and snow model simulations to better predict future contributions of the Greenland ice sheet to global sea level rise.

AbstractIn recent decades, the Greenland ice sheet has experienced increased surface melt. However, the underlying cause of this increased surface melting and how it relates to cryospheric changes
Climatic signal of ice melt features in southern Greenland
The stratigraphie record of melt features in intermediate depth polar ice cores has provided valuable data on past summer climate1–3. The thermal drilling technique used in previous studies precluded
Changes in the firn structure of the western Greenland Ice Sheet caused by recent warming
Abstract. Atmospheric warming over the Greenland Ice Sheet during the last 2 decades has increased the amount of surface meltwater production, resulting in the migration of melt and percolation
