Major Antarctic glacier is 'past its tipping point' - environment - 13 January 2010 - New Scientist

According to Katz's model, the grounding line probably passed over the crest in 1996 and is now poised to enter a period of accelerated shrinking.
The model suggests that within 100 years, PIG's grounding line could have retreated over 200 kilometres. "Before the retreating grounding line comes to a rest at some unknown point on the inner slope, PIG will have lost 50 per cent of its ice, contributing 24 centimetres to global sea levels," says Richard Hindmarsh of the British Antarctic Survey, who did not participate in the study.

Sounds grim.

While I have little doubt that the reports are accurate, I do have some doubts about long term projections based on trend line analysis.

Now that isn't a good thing.

It doesn't mean that I think that things won't be that bad, necessarily, or that I think things will be much worse than projected, either.

What it means is that I KNOW that the system is so damned complex that we cannot know the outcomes in the long run.

Chaos theory...it's not just breakfast for math geeks, anymore.

Well, right now, the 'alarmists' have been missing the mark pretty much on the whole affair. They have been far to optimistic.

We are seeing the ice melting and moving at a far faster rate than we thought possible.

The ocean clathrates are already starting to outgass in the North Atlantic and the Artic Ocean. And we can measure the result now in our atmosphere.


Because we obviously do not understand all the complexities involved, we are hoping for a negative feedback that we are not seeing at present.

However, as you pointed out, choas reigns. A change of state in the climate, and things get real interesting, fast!

Don't worry guys

We'll all be long gone before the planet dies.

The planet is not going to die. But we are already in the Sixth great extinction event. And that could culminate in the extinction of certain species of naked apes.

Yawn

Mindless derision from the mindless.

So we're all gonna die.

Everybody dies. Why should humans be any different?

Could be a case of getting back what's given, heh?

Yes, we call it the "George Costanza Effect" -- cold water causes shrinkage

The Invisible CO2 Spaghetti Monster is eating a Glacier (according to the models) Eeeeeeekkk!!! Run for the hills!!!

Until the invention of the SUV we never, ever, never, ever lost a single glacier in million of years!!

glaciers come..glaciers go. They are ice for God's sake.

Now if they were iron you might get my attention.

Fact, do you ever bother to read the article?

The team's work will be published in a forthcoming issue of Annals of Glaciology.

Surging glaciers are common and do not necessarily mean a glacier is growing in overall size. But the fact that dozens of them have all surged in the same region hints that larger climate forces are at work.

"It looks like it's the Westerlies," Shroder said, referring to strong jets of wind that pour from west to east in a belt around the planet. Though he can't say for certain, the winds appear to be carrying more moisture from the warming Atlantic Ocean and Mediterranean Sea eastward.

If that's true, some of the moisture would fall into the region around the Caspian Sea. But as the winds rise into Karakoram's frigid heights, any remaining water would come down as snow, feeding the glaciers.

"We will see regional patterns like this developing as climate change alters precipitation," said Andrew Fountain of Portland State University in Oregon.

Fountain said that similar trends were evident in some Scandinavian glaciers during the 1990s, which benefited from increased storminess and precipitation coming off the North Atlantic Ocean. Researchers have also found that glaciers on California's Mt. Shasta have been growing for decades. And glacier recession has been blunted in the mountains of Oregon and Washington state because of increased moisture from the warming Pacific Ocean.

In the Karakorams, the uptick in glacier mass has come with a welcomed perk. The mighty Indus River, which flows out of China and nourishes northern India and much of Pakistan has experienced an increase in discharge.

But it's not likely to last.

"As temperatures continue increasing, they will overtake additional mass provided by snow," Fountain said. "The freezing level will keep rising, and glaciers will melt."

From the article it is quite obvious that these are the exceptions, and even gives the reason at to why they are the exceptions. But you people try to act as if all the glaciers in the Himalayas are growing. So, are you just stupid, or merely dishonest?

Himalayan Glaciers Seem to Be Growing : Discovery News

Perched on the soaring Karakoram mountains in the Western Himalayas, a group of some 230 glaciers are bucking the global warming trend. They're growing.

Throughout much of the Tibetan Plateau, high-altitude glaciers are dwindling in the face of rising temperatures. The situation is potentially dire for the hundreds of millions of people living in China, India and throughout southeast Asia who depend on the glaciers for their water supply.

But in the rugged western corner of the plateau, the story is different, according to a new study. Among legendary peaks of Mt. Everest like K2 and Nanga Parbat, glaciers with a penthouse view of the world are growing, and have been for almost three decades.

"These are the biggest mid-latitude glaciers in the world," John Shroder of the University of Nebraska-Omaha said. "And all of them are either holding still, or advancing."

When Shroder and a team of researchers examined satellite imagery of the region's glaciers dating back to 1960, they found that 87 glaciers had surged forward during that time, sliding down into lower elevations. An analysis of gravity signatures in the region also suggests the glaciers are growing in mass, and have been since at least 1980
