Velicogna and her colleagues also measured a dramatic loss of Greenland ice, as much as 38 cubic miles per year between 2002 and 2005 — even more troubling, given that an influx of fresh melt water into the salty North Atlantic could in theory shut off the system of ocean currents that keep Europe relatively warm.

They observed three types of ice losses, each with a distinctive and detailed sound signature: the splash of an ice block falling off into the water; the crack of a fragment sliding down the glacier's rough surface; and the soft thud of an underwater ice chunk breaking away and floating up, followed by a secondary impact as it surfaces.

The results do suggest however that if sea ice loss continues as it has over recent decades, the risk of wet summers may increase.

The researchers find that «ocean - driven melt is an important driver of Antarctic ice shelf retreat where warm water is in contact with shelves, but in high greenhouse - gas emissions scenarios, atmospheric warming soon overtakes the ocean as the dominant driver of Antarctic ice loss.»

The researchers warn, however, that the future evolution of the AMO remains uncertain, with many factors potentially affecting how it interacts with atmospheric circulation patterns, such as Arctic sea ice loss, changes in solar radiation, volcanic eruptions and concentrations of greenhouse gases in the atmosphere.

The melting of Greenland contributes to the global sea level, but the loss of mass also means that the ice sheet's own gravitational field weakens and thus does not attract the surrounding sea as strongly.
