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.

Take Holland: It will be much more heavily influenced by Antarctic ice melt than by falling sea levels around Greenland, says Jerry Mitrovica, a geophysicist and sea level modeler at Harvard University.

Within a few hundred years sea levels in some places had risen by as much as 10 meters — more than if the ice sheet that still covers Greenland were to melt today.

All told, if the eastern and western Antarctic ice shelves were to melt completely, they would raise sea levels by as much as 230 feet (70 meters); the collapse of smaller shelves like Larsen B has sped up the flow of glaciers behind them into the sea, contributing to the creeping up of high tide levels around the world.

In Greenland this doesn't happen much because the water drains away through big channels like the mega-canyon, so melting ice sheets there tend not to drive rapid sea level rises.

Schimdt has found evidence that warm ocean currents and convective forces beneath Europa's frozen shell can cause large blocks of ice to overturn and melt, bringing vast pockets of water, sometimes holding as much liquid as all of the Great Lakes combined, to within several kilometers of the moon's icy surface.

That is bad news, because warm water melts ice much faster than warm air.

«In recent years Arctic pack ice has formed progressively later, melted earlier, and lost much of its older and thicker multi-year component,» says Anthony Fischbach of the US Geological Survey (USGS) and one of the research team.

Ullman said the level of CO2 that helped trigger the melting of the Laurentide ice sheet was near the top of pre-industrial measurements — though much less than it is today.
