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 temperatures. However, in situ observational records of GrIS melt rates over recent decades are rare. Here we develop a record of frozen meltwater in the west GrIS percolation zone preserved in seven firn cores. Quantifying ice layer distribution as a melt feature percentage (MFP), we find significant… Expand

Past Warmth and Its Impacts During the Holocene Thermal Maximum in Greenland
Higher boreal summer insolation in the early to middle Holocene drove thousands of years of summer warming across the Arctic. Modern-day warming has distinctly different causes, but geologic dataExpand
Meteorological Drivers and Large-Scale Climate Forcing of West Antarctic Surface Melt
Understanding the drivers of surface melting in West Antarctica is crucial for understanding future ice loss and global sea level rise. This study identifies atmospheric drivers of surface melt onExpand

Abstract. One consequence of recent Arctic warming is an increased occurrence and longer seasonality of above-freezing air temperature episodes. There is significant disagreement in the literatureExpand
Drivers of Firn Density on the Greenland Ice Sheet Revealed by Weather Station Observations and Modeling
Recent Arctic atmospheric warming induces more frequent surface melt in the accumulation area of the Greenland ice sheet. This increased melting modifies the near-surface firn structure and densityExpand
Firn cold content evolution at nine sites on the Greenland ice sheet between 1998 and 2017
Abstract Current sea-level rise partly stems from increased surface melting and meltwater runoff from the Greenland ice sheet. Multi-year snow, also known as firn, covers about 80% of the ice sheetExpand
Firn data compilation reveals widespread decrease of firn air content in western Greenland
Abstract. A porous layer of multi-year snow known as firn covers the Greenland-ice-sheet interior. The firn layer buffers the ice-sheet contribution to sea-level rise by retaining a fraction ofExpand
Shallow firn cores 1989–2019 in southwest Greenland's percolation zone reveal decreasing density and ice layer thickness after 2012
Refreezing of meltwater in firn is a major component of Greenland ice-sheet's mass budget, but in situ observations are rare. Here, we compare the firn density and total ice layer thickness in theExpand


Has Arctic Sea Ice Loss Contributed to Increased Surface Melting of the Greenland Ice Sheet
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 changesExpand
Greenland ice-sheet contribution to sea-level rise buffered by meltwater storage in firn
The existing water storage capacity of the percolation zone of the Greenland ice sheet is quantified and the potential for hundreds of gigatonnes of meltwater storage is shown, finding that decades are required to fill this pore space under a range of plausible future climate conditions. Expand

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 percolationExpand
Linking interannual variability in extreme Greenland blocking episodes to the recent increase in summer melting across the Greenland ice sheet
Atmospheric blocking commonly occurs over the high latitudes of the Northern Hemisphere, resulting from the development of persistent areas of high pressure that lead to warmer-than-average surfaceExpand
