Greenland's ice cap thickens

Greenland ice cap thickens slightly

Friday, October 21, 2005; Posted: 10:21 a.m. EDT (14:21 GMT)

OSLO, Norway (Reuters) -- Greenland's ice cap has thickened slightly in recent years despite wide predictions of a thaw triggered by global warming, a team of scientists said on Thursday.

The 9,842-feet thick ice cap is a key concern in debates about climate change because a total melt would raise world sea levels by about 7 meters. And a runaway thaw might slow the Gulf Stream that keeps the North Atlantic region warm.

But satellite measurements showed that more snowfall was falling and thickening the ice cap, especially at high altitudes, according to the report in the journal Science.

Glaciers at sea level have been retreating fast because of a warming climate, making many other scientists believe the entire ice cap was thinning.

"The overall ice thickness changes are ... approximately plus 1.9 inches a year or 21.26 inches over 11 years," according to the experts at Norwegian, Russian and U.S. institutes led by Ola Johannessen at the Mohn Sverdrup center for Global Ocean Studies and Operational Oceanography in Norway.

However, they said that the thickening seemed consistent with theories of global warming, blamed by most experts on a build-up of heat-trapping gases from burning fossil fuels in power plants, factories and cars.

Warmer air, even if it is still below freezing, can carry more moisture. That extra moisture falls as snow below 32 Fahrenheit.

And the scientists said that the thickening of the ice-cap might be offset by a melting of glaciers around the fringes of Greenland. Satellite data was not good enough to measure the melt nearer sea level.

Most models of global warming indicate that the Greenland ice might melt within thousands of years if warming continues.

Oceans would rise by about 70 meters if the far bigger ice-cap on Antarctica melted along with Greenland. Antarctica's vast size acts as a deep freeze likely to slow any melt of the southern continent.

The panel that advises the United Nations has predicted that global sea levels might rise by almost a meter by 2100 because of a warming climate.

Such a rise would swamp low-lying Pacific islands and warming could trigger more hurricanes, droughts, spread deserts and drive thousands of species to extinction.

Still, a separate study in Science on Thursday said sea levels were probably rising slightly because of a melt of ice sheets.

"Ice sheets now appear to be contributing modestly to sea level rise because warming has increased mass loss from coastal areas more than warming has increased mass gain from enhanced snowfall in cold central regions," it said.

"Greenland presently makes the largest contribution to sea level rise," according to the report by scientists led by Richard Alley of Pennsylvania State University in the United States.

Fuckers want it both ways.
If the glaciers recede, it must be caused by "global warming."
And if they advance? It must be "global warming."

A more precise term would be "global climate shift." The warming caused by greenhouse gasses is supposed to change weather patterns in such a way that certain parts of the world would get cooler(and some say would even bring us into the next ice age). No one's having it both ways.

Nice to see you applying such scientific thought to this. Keep it up  :thumbup:

Of course it is. If they could not make it consistant with their own theories, they wouldn't publish it.

Its true and were due for a global climate shift the last one we had was 6,000 to 12,000 years ago. However maybe greenhouse gasses are advancing the climate shift.

There has no doubt, been damage done to the environment. Often it's localized like acid rain, but either way it's best to play it safe when it comes to reducing potential harm. Waiting for evidence of damage (especially when there already is evidence) is rather pointless.

But taking any action will cost the corporations an enormous amount of money. And seeing as Bush is in their pocket no action will ever be taken. The planet will be destroyed for the sake of a few executive directors wanting to award themselves enormous pay rises year on year.

In the short-term, it may cost corporations a certain amound of profit. But sustainability is ultimately more cost-effective in the long run, and corporations who realize this are sure to have the last laugh.

It will cost corporations nothing. Either way, corporations will make money and whiny bitches will whine. And Lexx is looming anyway so why worry.
