R. Kerr
Greenland Rumbles Louder as Glaciers Accelerate
I. Joughin
Hitting the Ice Sheets Where It Hurts
R. Bindschadler

Paleoclimatic Evidence for Future Ice-Sheet Instability and Rapid Sea-Level Rise
J. T. Overpeck et al.
Simulations of Earth's climate 130,000 years ago, compared with warming projected to occur over the next century, imply that widespread melting of the Greenland Ice Sheet is possible.
Simulating Arctic Climate Warmth and Icefield Retreat in the Last Interglaciation
B. L. Otto-Bliesner et al.
Simulations of ice dynamics and climate 130,000 years ago indicate that melting of ice sheets in Greenland and the Canadian Arctic raised sea level by 2.2 to 3.4 meters.
Measurements of Time-Variable Gravity Show Mass Loss in Antarctica
I. Velicogna and J. Wahr
Satellite measurements of Earth's gravity reveal that the mass of ice in Antarctica decreased from 2002 to 2005, mainly from losses in the West Antarctic Ice Sheet.
Seasonality and Increasing Frequency of Greenland Glacial Earthquakes
G. Ekström, M. Nettles, V. C. Tsai
Greenland glacier earthquakes produced beneath ice streams and outlet glaciers occur more often in summer and have doubled in frequency over the past 5 years.
