Greenland's glaciers have been shrinking for 100 years: study

[w¡n9Nµ7 §£@¥€r 123]

Greenland's glaciers have been shrinking for the past century, according to a Danish study, suggesting that the ice melt is not a recent phenomenon caused by global warming.

Danish researchers from Aarhus University studied glaciers on Disko island, in western Greenland in the Atlantic, from the end of the 19th century until the present day.

"This study, which covers 247 of 350 glaciers on Disko, is the most comprehensive ever conducted on the movements of Greenland's glaciers," glaciologist Jacob Clement Yde, who carried out the study with Niels Tvis Knudsen, told AFP.

Using maps from the 19th century and current satellite observations, the scientists were able to conclude that "70 percent of the glaciers have been shrinking regularly since the end of the 1880s at a rate of around eight meters per year," Yde said.

"We studied 95 percent of the area covered by glaciers in Disko and everything indicates that our results are also valid for the glaciers along the coasts of the rest of Greenland," he said.

The biggest reduction was observed between 1964 and 1985.

"A three-to-four degree increase of the temperature on Greenland from 1920 to 1930, and the increase recorded since 1995 has sped up the ice melt," he said.

The effect of the rising temperatures in the 1920s and 1930s was "visible dozens of years later, and that of the 1990s will be (visible) in 10 or 20 years," Yde said, adding that he expected Greenland's glaciers to melt even faster in the future.

The shrinking of the glaciers since the 19th century is "the result of the atmosphere's natural warming, following volcanic eruptions for example and greenhouse gases, created by human activities, which have aggravated the situation further," he said.

The study also showed new results on galloping glaciers, the name given to glaciers that surge very quickly for a few years, up to 50 meters a day, before advancing more slowly at a rate of 20 meters per year," he said.

"We have identified, thanks to new analyses of aerials photographs and satellite images, almost four times more galloping glaciers, or 75 compared to just 20 in previous estimates," he said.

The two authors of the study were to present their results on Monday at a conference in Cambridge, England on the impact of global warming on glaciers.

I guess i'm not so safe in Michigan.

duh! we've been warming up since the last ice-age 12,000 years ago.

Go see An Inconvienent Truth and you'll stop making ignorant comments about global warming.

just where were those data collection centers located at anyway? (serious here)

Let's just explain it to him with cold, hard data. (Ok, you do it, I have to go to bed)

Seriously, go see the movie and then if you're still confused, unsure or just skeptical than I don't know what else would convince you.

really... we haven't been warming up for the past 12,000 years? It's actually just one of many warming periods. And they occured long before man unleashed his evil technology (which you use with reckless abandon I'd guess).

I'd do it but I'd be doing a disservice to the movie and to the science behind it. I saw it for the first time this last Saturday night - I went from shock to despair to a sense of hope...that any reasonably minded person will understand the facts presented in the movie and realize what we are up against.

I'm not going to try get into a quasi-scientific debate with you here. Go see the movie...you'll be glad you did...and you'll realize just ignorant your comments are.

I'm ignorant because I haven't seen Al Gore's movie? It's propaganda and you know it. He did invent the internet though. So I have mixed feelings.

What caused our last ice-age to end?

Yeah watch anything and listen to anything from Al Gore and you will stop making ignorant comments about global warming!

Only problem is once you start thinking like Al Gore you will start making ignorant comments about everything--remember it was Al Gore that initiated the creation of the Internet.

Other Classic Al Gore ignorant comments

Hey Steven how does Jinky feel about you lusting for Rosario Dawson all the time?

If you go see it, and it doesn't change your understanding about global warming, I'll reimburse you for the ticket..You, Artegal and Gupt. I'll reimburse all 3 of you.
