Satellite altimetry has shown that global mean sea level has been rising at a rate of ∼3 ± 0.4 mm/y since 1993. Using the altimeter record coupled with careful consideration of interannual and decadal variability as well as potential instrument errors, we show that this rate is accelerating at 0.084 ± 0.025 mm/y2, which agrees well with climate model projections. If sea level continues to change at this rate and acceleration, sea-level rise by 2100 (∼65 cm) will be more than double the amount if the rate was constant at 3 mm/y.

Greenland’s vast ice sheet has long been home to Project Iceworm, an abandoned Cold War-era U.S.

Moulins permit access of surface meltwater to the glacier bed, causing basal lubrication and ice speedup in the ablation zone of western Greenland during summer. Despite the substantial impact of moulins on ice dynamics, the conditions under which they form are poorly understood. We assimilate a time series of ice surface velocity from a network of eleven Global Positioning System receivers into an ice sheet model to estimate ice sheet stresses during winter, spring, and summer in a ∼30 × 10 km region.

Up to four times more coastal glaciers in Greenland are at risk of accelerated melting than previously thought, say scientists who have mapped the region's coastal seafloor and bedrock beneath its

Melting ice is causing coastal waters in Greenland to become less saline, which may in turn affect marine life as well as the global ocean currents that keep Europe warm, a study warns.

According to local scientists and specialists in Denmark, the population of the dogs – traditionally used for transporting people and goods across Greenland’s vast snowy landscape and also for sle

New images have been released of wildfires that continue to burn close to the Greenland ice sheet, on the country's west coast.

The rise in global sea levels has accelerated since the 1990s amid rising temperatures, with a thaw of Greenland's ice sheet pouring ever more water into the oceans, scientists said on Monday.

Scientists have found that vast lakes and streams are widespread on the surface of Antarctica's ice sheets which may accelerate its contribution to the rise in sea-level, a new study suggests.
