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.

Some coastal areas are going up by nearly 1 inch per year, the scientists announced today. If current trends continue, that could accelerate to as much as 2 inches per year by 2025, said Tim Dixon, professor of geophysics at the University of Miami Rosenstiel School of Marine and Atmospheric Science (RSMAS) and principal investigator of the study.

"It's been known for several years that climate change is contributing to the melting of Greenland's ice sheet," Dixon said in a statement. "What's surprising, and a bit worrisome, is that the ice is melting so fast that we can actually see the land uplift in response."

Dixon added: "Even more surprising, the rise seems to be accelerating, implying that melting is accelerating."

The results, based on a study of data from global positioning system (GPS) receivers stationed on the rocky shores of Greenland, were published online by the journal Nature Geoscience. The data stretches back to 1995.

"During ice ages and in times of ice accumulation, the ice suppresses the land," explained Shimon Wdowinski, research associate professor in the University of Miami RSMAS, and co-author of the study. "When the ice melts, the land rebounds upwards," Wdowinski said. "Our study is consistent with a number of global warming indicators, confirming that ice melt and sea-level rise are real and becoming significant."

      It means the potential for faster sea level rise, though I don't recall Al Gore being mentioned anywhere in the article or this thread. Some of you sock puppets need to change the record. Oh, and it's NOBEL.

      Excerpt:

      "Greenland's ice is melting at such a rapid pace that the land beneath it is rising up, say U.S. researchers.

      The dense, two-kilometre thick icecap that covers Greenland suppresses the land, keeping its elevation in check, researchers at the University of Miami write in a new study. However, it is melting so quickly that the island's coastal areas are rising at a rate of one inch per year.

      The scientists predict that by 2025, that rate could be two inches a year.

      "What's surprising, and a bit worrisome, is that the ice is melting so fast that we can actually see the land uplift in response," said the study's principal investigator, Tim Dixon, professor of geophysics at the University of Miami Rosenstiel School of Marine and Atmospheric Science (RSMAS), in a news release.

      "Even more surprising, the rise seems to be accelerating, implying that melting is accelerating."

      To determine the rise of the land, the researchers used a global positioning system (GPS) on the shores of Greenland to determine the precise increases in the rise of a variety of coastal areas since 1995.

      The GPS determined that the increases in land elevation began in the mid-1990s.

      "Greenland's ice melt is very important because it has a big impact on global sea level rise," said study co-author Yan Jiang, a PhD candidate at RSMAS.

      Yiang said that Greenland could soon become the biggest factor in a rise in sea levels around the world.

      The study is published in the May 16 issue of Nature Geoscience.

    • So what in this over 900 page "climate" bill truly addresses this? Greenland isn't waiting for a piece of paper. Neither is the Arctic, or the Himalayas. I hope this so called "new age" that is predicted comes soon. We've already passed the tipping point on glacier melt.

      "We've already passed the tipping point on glacier melt."
      So if that's true (and it isn't) then why do we read headlines like this:

      24 Jan 10 - "The scientist behind the bogus claim in a Nobel Prize-winning
      UN report that Himalayan glaciers will have melted by 2035 last night admitted
      it was included purely to put political pressure on world leaders."

      Surely if things are as bad as you say then there will be no need to hype the headlines, reality will speak for itself. The problem is real-world evidence doesn't match up to what the alarmists' tell us is happening.

      Hindu Kush and the Karakoram glaciers in the Himalayas are "thickening and expanding", so not all glaciers are shrinking - far from it. And now you'll hit me with a list of Al Gore approved websites which show that there are countless glaciers that are melting at "alarming" or "unprecedented" rates. So would you also be able to prove that all glacier melt was due to increasing temperatures? Probably not:
      The Chacaltaya glacier in Bolivia has been receding even though temperatures in that area are falling at around -0.2ºC/decade. Why do you think that could be?

      I always find it amusing how we read stories of Arctic ice melt at this time of year, when Arctic ice is melting. You must have been so happy in the winter when Arctic ice was building up, reaching higher levels than previous years. But I doubt it, nothing seems to make you happy - life has to be full of doom and gloom, there has to be a catastrophe waiting in the wings, and it has to be man's fault - has to be!

      Ola Johannessen at the Mohn Sverdrup center for Global Ocean Studies and Operational Oceanography in Norway found that the ice in Greenland was thickening at a rate of 1.9 inches a year, and we're now seeing Arctic ice extent and thickness increasing again. Slightly at odds with this article, then, but instead of looking into the research with an open mind, most people here will instantly dismiss anything that goes against the 'global warming' mantra, and that is nothing to be proud of.

      Because there is more to the world than what you CHOOSE to cherrypick and twist for your own agenda. And that "ice" in the Arctic was in the Bering Strait and already explained by NSIDC (not an "Al Gore site" for your information) as being due to weather in that area alone, with ice continuing to melt elsewhere in the Arctic. How convenient of you once again to cherrypick. So look, I already KNOW what YOU are all about here and how ignorant you really are on this topic without your talking points, so excuse me if I come in this thread now to actually respond to people who discuss this based on ALL of the facts and the REAL scientists' cliams, not denialist politically motivated cherrypicked analyses and BS from paid off oil shill weathermen.

      You didn't have to insult "JanforGore" with your comment. "But I doubt it, nothing seems to make you happy - life has to be full of doom and gloom, there has to be a catastrophe waiting in the wings, and it has to be man's fault - has to be!" Don't act like you know people. Also with the "Al Gore" site comment. And I'm pretty much nuetral on this by the way. I understand both sides of the argument, but I don't think it's something worth arguing over - there's bigger problems out there.

      "If current trends continue, that could accelerate to as much as 2 inches per year"

      Could accelerate? Hardly scientific eh? Glacial rebound has been occurring at varying rates for centuries, this is nothing new.
      "Even more surprising, the rise seems to be accelerating, implying that melting is accelerating."

      Seems to be accelerating? Again, hardly scientific. Glacial rebound doesn't just suddenly spring to life, it happens over centuries. So we're supposed to be scared by this? Why, because sea levels will rise faster and swamp islands and coastal areas? But sea level rises have decelerated over the past few years, not accelerated (currently in the region of 1.5 mm/yr).
      The fact that sea levels have risen over the past 6000 years is not a cause for concern. At one time I could have walked to France (actually I'm not that old) but now there's a rather big sea in my way. The south of England is sinking while Scotland is experiencing the same glacial rebound as Greenland. Things change, sometimes slowly, sometimes relatively rapidly (in geological terms).
      Humans have to adapt to these changes, not just now but also in the centuries to come, because at some point way past our lifetimes there's going to be another ice age. You can bet your bottom $ (or £ in my case) that they won't be taxing CO2 production at that point.

      "Hardly scientific eh?"

      Sort of reminds me of you. Perhaps you should look into how the scientists make these predictions. That way, you wouldn't be compelled to say such stupid things and come off as an idiot.
