A new study shows that as a glacier's ice melts, bubbles of pressurized ancient air escape into the water, leading to noise levels even louder than those beneath rain - pounded seas heaving with 6 - meter waves.

Instead, the main source of the clamor occurs when bubbles disengage from the melting glacier and suddenly spring back into their original spherical shapes after thousands of years of being squeezed by the ice.

At its calving front, where the glacier effectively ends as it breaks off into icebergs, some of the ice melts while the rest is pushed out, floating into the ocean.

That's because the IPCC models only take into account temperature changes at the surface of glaciers, but not the rapid melting that occurs when glaciers calve and break up into the ocean, Rignot said.

Co-author Dr Ivan Haigh, lecturer in coastal oceanography at the University of Southampton and also based at NOCS, adds: «Historical observations show a rising sea level from about 1800 as sea water warmed up and melt water from glaciers and ice fields flowed into the oceans.

The melting of Snowball Earth glaciers apparently released phosphates ground off continental rocks into the oceans between 750 and 620 million years ago, causing levels of this vital nutrient to rise to levels higher than experienced before or since, and feeding oxygen - producing life which eventually supported the rise of newly developing oxygen - consuming «metazoans,» or animals (staff, New Scientist, October 27, 2010; and Planavsky et al, 2010).

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

However, Roland tells us, the ice shelves can retard the flow of glaciers into the sea, and speed up glacier melt when they disappear.

Either the glaciers would have to flow into the ocean at unrealistic rates, or rapid melting would have to be triggered over a much larger area of the ice sheet than current evidence suggests.

It is dissected by several gullies, cut into the unconsolidated sand by streams (melting from the glacier surface is encouraged by the accumulation of dark wind - blown sand, which absorbs solar radiation)[17].

This means that all the energy going into the melting of sea ice, ice sheets and glaciers plus the warming of land and atmosphere is the tiny gap between the blue area and the red line.

Unlike the great ice sheet of Antarctica, the Greenland ice sheet is melting both on its surface and also at outlet glaciers that drain the ice sheet's mass through deep fjords, where these glaciers extend out into the ocean and often terminate in dynamic calving fronts, giving up gigaton - sized icebergs at times.
