Greenland ice sheet faces 'tipping point in 10 years'

Scientists warn that temperature rise of between 2C and 7C would cause ice to melt, resulting in 23ft rise in sea level

* Suzanne Goldenberg, US environment correspondent

The entire ice mass of Greenland will disappear from the world map if temperatures rise by as little as 2C, with severe consequences for the rest of the world, a panel of scientists told Congress today.

Greenland shed its largest chunk of ice in nearly half a century last week, and faces an even grimmer future, according to Richard Alley, a geosciences professor at Pennsylvania State University

"Sometime in the next decade we may pass that tipping point which would put us warmer than temperatures that Greenland can survive," Alley told a briefing in Congress, adding that a rise in the range of 2C to 7C would mean the obliteration of Greenland's ice sheet.

The fall-out would be felt thousands of miles away from the Arctic, unleashing a global sea level rise of 23ft (7 metres), Alley warned. Low-lying cities such as New Orleans would vanish.

"What is going on in the Arctic now is the biggest and fastest thing that nature has ever done," he said.

1. And I love how nobody wants to talk at all about Antarctica, just occasional
fretting about the WAIS.

Prediction: 10 years from now will see serious fretting over Antarctic itself. The melt is on.

Anything above a 1m rise here, and we're in the swamp as are the major roads.

3. 7 years ago I moved near the coast
while I still could...but I'm still a couple hundred feet above sea level. I moved here (Maine) in part because my inner voice said, "there will be water." It wasn't until my 2nd year here, taking the Master Gardener Program, that I came to understand the water wars already underway. The 20th century wars were fought over oil. In the 21st century, wars will be fought over water. We're sitting on a major pure water aquifer and have been fighting Nestle legally as they've sued one village after another trying to expand Poland Springs.

16. What people don't fully grasp...
...is that scientists are struggling with all the data and are growing fearful that their projections have been much too conservative.

If anything they have erred on the side of caution, but now events seem to be moving at a more rapid clip than their models indicate.

It seems like every time they make a prediction they have to follow that with a correction and the correction usually involves reducing the timeframe or increasing the rate of change.

By the time the deniers finally realize their folly it will be too late for the rest of us. We will be too busy struggling to survive to issue a pointed "I told you so."
