Review article: Earth's ice imbalance [PDF]
We combine satellite observations and numerical models to show that Earth lost 28 trillion tonnes of ice between 1994 and 2017. Arctic sea ice (7.6 trillion tonnes), Antarctic ice shelves (6.5 trillion tonnes), mountain glaciers (6.1 trillion tonnes ...

Threatened loss of the Greenland ice-sheet [PDF]
The Greenland ice-sheet would melt faster in a warmer climate and is likely to be eliminated — except for residual glaciers in the mountains — if the annual average temperature in Greenland increases by more than about 3 °C. This could raise the global average sea-level by 7 metres over a period of 1,000 years or more.

Earliest Holocene south Greenland ice sheet retreat within its late Holocene extent [PDF]
Early Holocene summer warmth drove dramatic Greenland ice sheet (GIS) retreat. Subsequent insolation-driven cooling caused GIS margin readvance to late Holocene maxima, from which ice margins are now retreating.

Holocene deceleration of the Greenland Ice Sheet [PDF]
Keeping a stiff upper layer The interior of the Greenland Ice Sheet is growing thicker, in contrast to the thinning that is occurring at its edges. Why? MacGregor et al. conclude that more snow is accumulating and that the ice in the interior is flowing more slowly than it did thousands of years ago (see ...

An assessment of key model parametric uncertainties in projections of Greenland Ice Sheet behavior [PDF]
Lack of knowledge about the values of ice sheet model input parameters introduces substantial uncertainty into projections of Greenland Ice Sheet contributions to future sea level rise.

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.

Greenland Ice Sheet Ice Slab Expansion and Thickening
We use airborne accumulation radar data acquired over the Greenland Ice Sheet between 2002 and 2018 to identify changes in ice slab extent and thickness. We show that ice slabs several metres thick were already present at least as early as 2002. Between 2012 and 2018, they expanded 13,400-17,600 inland, or by 37-44%.

Recent deposition of 210Pb on the Greenland ice sheet: variations in space and time [PDF]
Detailed 210Pb profiles were determined for four Chernobyl dated\u27 snowpits sampled during a wide-ranging survey of the Greenland ice sheet during the 1988 season.

Recent Progress in Greenland Ice Sheet Modelling [PDF]
This paper reviews the recent literature on numerical modelling of the dynamics of the Greenland ice sheet with the goal of providing an overview of advancements and to highlight important directions of future research. In particular, the review is focused on large-scale modelling of the ice sheet, including future projections, model parameterisations,

Preservation of a Preglacial Landscape Under the Center of the Greenland Ice Sheet [PDF]
Continental ice sheets typically sculpt landscapes via erosion; under certain conditions, ancient landscapes can be preserved beneath ice and can survive extensive and repeated glaciation.
