Rare Glacial River Drains Potentially Harmful Lakes
Antarctic lakes have contributed to ice shelf breakup in the past, but a glacier in Greenland appears safe from a similar fate, thanks to a river that drains away water.

Accounting for Accelerated East Coast Sea Level Rise
An analysis of tide gauge records and physical models shows acceleration of sea level rise on the East Coast due to melting of the Greenland Ice Sheet is especially pronounced south of 40°N latitude.
