Scientists Say Greenland Just Opened Up a Major New ‘Floodgate’ of Ice Into the Ocean

By Chris Mooney November 12 at 2:00 PM

As the world prepares for the most important global climate summit yet in Paris later this month, news from Greenland could add urgency to the negotiations. For another major glacier appears to have begun a rapid retreat into a deep underwater basin, a troubling sign previously noticed at Greenland’s Jakobshavn Glacier and also in the Amundsen Sea region of West Antarctica.

And in all of these cases, warm ocean waters reaching the deep bases of marine glaciers appears to be a major cause.

The new fast-moving glacier is the Zachariae glacier or Zachariæ Isstrøm, located in the far northeastern part of Greenland. In a new paper in Science, Jeremie Mouginot of the University of California-Irvine and his colleagues find that the ocean-based glacier, which contains 0.5 meters or a foot and a half of potential sea level rise, has begun a rapid retreat, especially since 2012. The glacier has lost fully 95 percent of the ice shelf that used to help stabilize it, they say, and now sports a 75 meter high ice cliff extending above the water (the glacier also extends hundreds of additional meters below it).

“This is sort of the second major floodgate from Greenland that has opened up,” says Eric Rignot of UC-Irvine and NASA’s Jet Propulsion Laboratory, one of the authors of the study. The first, says Rignot, was the Jakobshavn glacier, Greenland’s “fastest” moving, according to a recent study, which is currently based 1,300 meters below sea level and also retreating into a deep basin.

at some point (if not already), the acceleration of ice loss will be unstoppable. then we are truly attached to another object on an incline plane wrapped helically around an axis.

some say it can be "mitigated".
If you listen and read carefully you can see scientists no longer talk about avoiding climate chaos.
More and more 'moderate' sources like Salon and HuffMo - not exactly extreme in their reporting - are publishing pieces indicating that the window of opportunity is gone.
http://www.huffingtonpost.com/louise-leakey/human-extinction_b_3543036.html

A good source on climate reporting is:
Dahr Jamail
http://www.truth-out.org/news/item/28864-species-extinctions-human-chronic-disease-on-the-rise-as-climate-disruption-mounts


I think if any mitigation can be done, it will be slight and meaningless.

This is the time, imo, to be honest as a human race and acknowledge that we have fucked up royally.
Not that I expect to ever see it.

But I think of the words of Phil Ochs, "At the end end, even treason is worth a try."
In this case "treason" is to tell the truth,
which most people cannot hear.

For example this man tells the truth and the science backs him up:

And glacier melt cools the ocean, which makes the ocean fall some (so far rising sea levels are mostly from thermal expansion).

The precise effects of a given glacier's breaking up can be difficult to predict.

It's an old article but I think still relevant...

Retreating Glaciers Spur Alaskan Earthquakes

http://www.nasa.gov/vision/earth/environment/glacier_quakes.html

Scientists at NASA and United States Geological Survey (USGS) are using NASA satellite and global positioning system receivers, as well as computer models, to study movements of Earth's plates and shrinking glaciers in southern Alaska. Glaciers here are very sensitive to climate change. Higher temperatures and changes in precipitation over the last 100 years appear to be contributing to an increase in glacier melting in the area.

Southern Alaska is also prone to earthquakes because a tectonic plate under the Pacific Ocean is pushing into the coast, building up lots of pressure. The weight of a big glacier on top of these earthquake active areas can help keep things stable. But, as the glaciers melt and their load on the plate lessens, there is a greater likelihood of an earthquake happening to relieve the large strain underneath. Even though shrinking glaciers make it easier for earthquakes to occur, the forcing together of tectonic plates is the main reason behind major earthquakes.

Which might be just fine for human civilization. Or not. We really have no way of knowing.

Mass migrations, on the other hand, combined with depleted resources, point to escalation of conflict throughout the world. Combined with accelerating access to highly efficient technologies for killing other people, and/or general destruction ....

well I think you get the picture.
