But that could soon change, Rignot said, because the rate at which ice sheets are losing mass is increasing three times faster than the rate of ice loss from mountain glaciers and ice caps.

«Thus the increased snowfall we report here has not led to thickening of the ice sheet, but is in fact another symptom of the changes that are driving contemporary ice sheet loss.»

We know, however, that rapid warming of the planet increases the risk of crossing climatic points of no return, possibly setting in motion large - scale ocean circulation changes, the loss of major ice sheets, and species extinctions.

The team also compared the ice loss up until the mid-1980s to that observed by satellites over roughly the last decade and found that today the rate of ice loss is twice the 20th century average, mostly because of increased water runoff from the ice sheet's surface.

To take a specific example, the largest deviation (missing heat) was adequately explanained by increased heat exchange between 0 - 700 and 700 - 2000m ocean layers, so would it now be time to get the Arctic ice loss and the China - India brown cloud effect on Siberia and North Pacific correct?
