Melting near the edges of the Greenland ice sheet, where the surface is below 4,000 feet, causes about half of its annual ice loss.

When the planet's big ice sheets collapsed at the end of the last ice age, their melting caused global sea levels to rise as much as 100 meters in roughly 10,000 years, which is fast in geological time, Mann noted.

Contrary to what you might expect, the third IPPC report predicted that global warming would most likely lead to a thickening of the ice sheet over the next century, with increased snowfall compensating for any melting cause by warming.

The academics suggest that the melting of the ice sheet may have been caused in part by the fact that some of it rests in basins below sea level.

Some have wondered whether the melting of the Cordilleran Ice Sheet caused the Younger Dryras cooling, but it's unlikely; the cooling started too early for that to be true, according to the study.

A new study by scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, and the University of California, Irvine, shows that while ice sheets and glaciers continue to melt, changes in weather and climate over the past decade have caused Earth's continents to soak up and store an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, temporarily slowing the rate of sea level rise by about 20 percent.

The unstoppable retreat is the likely start of a long - feared domino effect that could cause the entire ice sheet to melt, whether or not greenhouse gas emissions decline.

Gerhard Kuhn, co-author of the study, said, «Our results provide evidence that in the past, [West Antarctic Ice Sheet -RCB- retreat was also predominantly caused by melting through warm ocean water.»

And on July 11 - 12 last year, gusts of warm air caused melting on virtually the entire surface of the ice sheet.

Melting glaciers and ice sheets are releasing cancer - causing pollutants into the air and oceans, scientists say.

Beyond sea ice, Greenland's ice sheet is also melting away and pushing sea levels higher, large fires are much more common and intense in boreal forests and other ecosystem changes are causing the earth to hyperventilate.

For example, the ice age — interglacial cycles that we have been locked in for the past few million years seem to be triggered by subtle changes in the earth's orbit around the sun and in its axis of rotation (the Milankovitch cycles) that then cause ice sheets to slowly build up (or melt away)... which changes the albedo (reflectance) of the earth amplifying this effect.
