Using satellite radar interferometry observations of Greenland, we detected widespread glacier acceleration below 66° north between 1996 and 2000, which rapidly expanded to 70° north in 2005. Accelerated ice discharge in the west and particularly in the east doubled the ice sheet mass deficit in the last decade from 90 to 220 cubic kilometers per year. As more glaciers accelerate farther north, the contribution of Greenland to sea-level rise will continue to increase.

Response of the global ocean to Greenland and Antarctic ice melting (2008, background): “…heat content anomalies due to an atmospheric CO2 increase, our focus here is the ocean’s response to melt water forcing around Greenland and Antarctica that according to recent measurements significantly increased during the last few years (Velicogna and Wahr, 2005; Rignot and Kanagaratnam, 2006).”
‘Calving laws’, ‘sliding laws’ and the stability of tidewater glaciers (2007, background): “Recently, calving glaciers in many parts of the world have undergone dramatic acceleration and retreat (e.g. Venteris, 1999; Thomas and others, 2004; Howat and others, 2005; Luckman and Murray, 2005; Rignot and Kanagaratnam, 2006), indicating a highly nonlinear response to initial climatic forcing.”
Increasing rates of ice mass loss from the Greenland and Antarctic ice sheets revealed by GRACE (2009, methodology): “This is the main reason why the recent IPCC 4th Assessment Report [Intergovernmental Panel on Climate Change, 2007] did not predict a large contribution for Greenland and Antarctica to total sea level rise over the next century.”
A simple mechanism for irreversible tidewater glacier retreat (2007, background): “The dynamics of ice-ocean interaction at marine termini bears on a wide range of important problems, from iceberg hazards [Tangborn and Post, 1998] to the determination of sea level inputs from Alaska, Arctic Canada, Greenland and Antarctica [Thomas et al., 2000; Arendt et al., 2002; Rignot and Kan”
Climate Models: An Assessment of Strengths and Limitations (2008, background): “However, observations via satellite altimetry, synthetic aperture radar interferometry, and gravimetry all suggest rapid dynamic variability of ice sheets, possibly in response to climatic warming (Rignot and Kanagaratnam 2006; Velicogna and Wahr 2006).”
The impact of sea level rise on developing countries: a comparative analysis (2007, background): “However, new data on rates of deglaciation in Greenland and Antarctica suggest greater significance for glacial melt, especially due to the uncertainty surrounding the dynamics of outlet glaciers (Hansen et al. 2005; Hanna et al. 2005; Howat et al.2007; Krabill et al. 2004; Meier et al. 2007; Rigno”
Coupled Human and Natural Systems (2007, background): “Greenland ice sheet collapse could have been entrained by a changing climate a long time before it can be easily discerned (99).”
Calving on tidewater glaciers amplified by submarine frontal melting (2012, background): “The calving of icebergs makes up a large component of the mass balance of many polar ice sheets and glaciers (Hagen et al., 2003; Rignot and Kanagaratnam, 2006).”
A physically based calving model applied to marine outlet glaciers and implications for the glacier dynamics (2010, background): “Rapid changes in ice dynamics of Greenland outlet glaciers have been documented in a number of recent studies (Thomas and others, 2003; Joughin and others, 2004, 2008a,b,c; Howat and others, 2005, 2007, 2008b; Luckman and others, 2006; Rignot and Kanagaratnam, 2006; Csatho and others, 2008; Moon and”
Forty-six years of Greenland Ice Sheet mass balance from 1972 to 2018 (2019, neutral): “in speed are also less in 1972–1992 (11, 18, 40).”
