Huge ice sheet breaks from Greenland glacier

The news report I saw on CNN was careful to point out that no cause had been determined. No mention of global warming AT ALL.

Your right, but that just doesn't play into Chris's "Fear Mongering" that the left likes to play.

Oh, in case you didn't see this:

UPDATE: The original story stated that the portion of the Jakobshavn Isbrae which broke off was seven square miles. It was, however, seven square kilometers, which is in fact 2.7 square miles.

Did I tell you about the ice cube that fell out of my glass when I miss judged a step from sun glare? True story.

Move along, you environmentalist wackaloon looky-loos.

I would not dismiss this too fast.

The flap of a butterfly’s wings in China might set off a tornado in Texas. Just think of all the chaos being caused by the worlds wind farms. Really. Wind turbines, clean power or death machines? Who knows?

You seem to think you know. Why should we pay attention to someone who admits to lack of knowledge?!?!

I seem to think I know what? (how to tell a joke?)

Pay attention to whomever you wish and by your own standard of judgement.

The ice is melting so fast in Greenland that the giant island is rising noticeably as the weight is lifted. In some spots, the land is rising 1 inch per year.

A vast ice cap covers much of Greenland, in some places up to 1.2 miles (2 km) thick. The ice, in place for eons, presses down the land, making the elevation at any given point lower than it would be sans ice.

Scientists have documented on Greenland and elsewhere that when longstanding ice melts away, the land rebounds. Even the European Alps are rising as glaciers melt.

Now, scientists at the University of Miami say Greenland's ice is melting so quickly that the land underneath is rising at an accelerated pace.

Dang, they better paint a yellow line around Greenland. Somebody might trip over that 1 inch rise. I mean, it wasn't there last year.

Jeez I hate to burst your bubble but you are talking about isostatic rebound that is occuring from the loss of ice from 10,000 years ago when the ice sheet was a minimum of 2 more miles thick. The area of the Great Lakes are also rebounding at the rate of 1 inch per year from the same cause.

As an aside though the Red Mountain Thrust Fault along the coast of California running from Carpinteria to Ventura is rising at 7 inches a year and the new Krakatoa is rising at the rate of five inches PER WEEK! That is impressive!

These changes on the Greenland ice sheet are happening fast, and we are definitely losing more ice mass than we had anticipated, " said Velicogna. "We also are seeing this ice mass loss trend in Antarctica, a sign that warming temperatures really are having an effect on ice in Earth's cold regions."

Researchers estimate that if melting in northwestern Greenland accelerates in major glaciers in the area, such as the Humboldt Glacier and the Peterman Glacier, Greenland's total ice loss could be increased by an additional 12 to 24 cubic miles within a few years.

Average air temperatures above Greenland's ice sheets have risen 4 degrees Fahrenheit since 1991.

Ice molecules have an additional side versus water. This should actually be a contraction right? Land deformation due to the weight of ice sounds like the current actions are a correction.

What "additonal side" are you talking about? What are you saying is contracting? Melting is due to the weight of the ice?!?! Your last sentence needs some explanation!

That is correct, that is why it is called a "rebound". You clearly understand the concept. I wonder why the alarmists can't.

The reason why the land is isostatically rebounding is because during the last ice age the weight of the ice on the continental landmass was forced down. Since the ice melted 10,000 years ago the land has been rebounding back to it's pre ice age elevation.

In other words it is quite normal. It also tells you that the ice was even THINNER (in other words it was warmer) beforehand because the land hasn't rebounded to it's normal level yet.

That massive ice island that broke off a Greenland glacier last week could potentially threaten North Atlantic shipping lanes and oil platforms off Canada, scientists say.

"It's so big that you can't prevent it from drifting. You can't stop it," Jon-Ove Methlie Hagen, a glaciologist at the University of Oslo, told the AP.

The island, estimated to be about 100 square miles, or about four times bigger than Manhattan, broke off the Petermann Glacier and is drifting toward the Nares Strait, separating Greenland from Ellsemere Island in Canada. If it reaches the strait before the winter freeze, which normally begins in September, the ice shelf would be carried south along Canada's east coast and reach shipping lanes and oil platforms off Newfoundland in one to two years, scientists say.

Though the behemoth would be expected to break apart after fender-benders with icebergs and islands, giant fragments might survive in the same waters where the Titanic sank in 1912.

Greenland calves around 10,000 icebergs a year. So this is not news, try again.

Yes and it is a sign of glacier health. No icebergs and you have a problem. Lots of icebergs and the glacier is healthy.

The University of St Andrews team said 106 square miles broke away from the Petermann Glacier at the beginning of August.

The massive ice island is is the largest single area loss observed for Greenland and suggests the effect of rising temperatures is affecting the Arctic faster than anticipated.

The finding immediately raises fears about the long term effect on rising sea levels and ultimately ‘positive feedbacks’ as water absorbs more heat than ice, therefore speeding up the warming effect.

Dr Richard Bates, who is monitoring the ice alongside researchers from America, said the expedition had expected to find evidence of melting this year after “abnormally high” temperatures in the area. Climate change experts say that globally it has been the warmest six months globally since records began.

But he was “amazed to see an area of ice three times the size of Manhattan Island had broken off.

“It is not a freak event and is certainly a manifestation of warming. This year marks yet another record breaking melt year in Greenland; temperatures and melt across the entire ice sheet have exceeded those in 2007 and of historical records.”

Come on, faux geologist, get it right. Isostatic rebound. As the ice melts, the land rises. Exactly what is being observed.
