Developing synoptic analogs for extreme mass balance conditions on Queen Elizabeth Island ice caps
. Journal of Climate and Applied Meteorology 26:1605-1623.
Until now, estimates of the ice caps
' thickness have been based on satellite and submarine images.
Carbon dioxide now frozen in rocks and polar ice caps
could be released, raising the planet's temperature and air pressure.
The surface of the north polar ice cap
has millions of closely-spaced pits no more than two meters deep.
"Most of the evidence for warming that we see in these high alpine ice caps
is in regions that are already water stressed," Mosley-Thompson notes.
Since then, the authors of the study say, the smallest glaciers and ice caps
on the coast have been unable to regrow lost ice.
Using lasers which measure the height of the ice from space, and a recently completed inventory of Greenland's glaciers and ice caps
, scientists from the European-funded ice2sea programme, were able to determine changes in the mass of those ice bodies, separate from the main ice sheet.
Parts of the Arctic and Antarctic are currently experiencing temperature rises far in excess of those seen elsewhere and scientists have expressed alarm at the rates at which parts of the polar ice caps
As more snow fell and local ice caps
thickened, glaciers flowed into surrounding lowlands.
SOME of Britain's most treasured bird species could be heading for extinction because of the melting polar ice caps
, a wildlife expert warns today.
By sending these machines on scouting missions to frozen ice caps
, deep oceans, and subterranean environments on our planet and someday others, researchers may eventually find that we're not alone in the universe after all.
Years of research and carefully collated data reveal to Professor Jack Hall (Quaid) that global warming and the subsequent melting of the polar ice caps
could soon herald a new Ice Age.
"Global warming" and melting ice caps
are myths promoted by tax-hungry politicians playing Canute.
Should the Canadian ice caps
melt completely, the global average sea level will rise by 20 centimetres.
Sir John, from Aberdyfi, said, "The polar ice caps
are certainly melting faster than they have done in recent history or for a long time.
