He was a thin-faced ascetic, living in a state of high, attenuated calm--a molten planet under a transcontinental ice sheet
. And yet, above all most of all, Daylight was impressed by the terrific and almost awful cleanness of the man.
A TEAM from Aberystwyth University has just returned from the Antarctic Peninsula with new information on the recent behaviour of the giant Antarctic Ice Sheet
The briefing was held five days after scientists reported that a 100-square-mile ice sheet
broke off from Greenland.
These findings will allow scientists to predict more accurately how global warming will affect ice sheets
and the potential for rising sea levels in the future by developing more robust climate and ice sheet
Summary: Scientists have discovered a shrimp-like creature and a jellyfish deep beneath a massive Antarctic ice sheet
Global warming could cause the huge Greenland ice sheet
to melt past "tipping points" from which it could not fully recover - even if carbon dioxide levels were slashed, a report has warned.
"If we can learn about the stability of the ice sheet
in the past, we can learn about its stability in the future.
A meltwater lake on the surface of a glacier suddenly emptied in July 2006, sending millions of gallons of water through cracks in the ice sheet
to the ground where it could affect the movement of the ice.
Annually, the Greenland ice sheet
gained approximately 11 billion tons of water, while Antarctica lost about 31 billion tons, for a net loss of ice to the sea.
The Antarctic ice sheet
, which holds 70 per cent of the world's fresh water, is shrinking at the rate of 36 cubic miles a year, scientists have revealed.
Some have warned in recent years, for instance, that the massive Greenland ice sheet
This is especially worrying because the glaciers in this area drain the West Antarctic Ice Sheet
, a precariously balanced portion of the southern ice cap that contains enough ice to raise sea levels by 20 feet.
