#NASA Scientists Say Antarctica Ice Shelf On Verge Of Collapse

NASA Study Shows Antarctica’s Larsen B Ice Shelf Nearing Its Final Act

A new NASA study finds the last remaining section of Antarctica's Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and likely to disintegrate completely before the end of the decade.

A team led by Ala Khazendar of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, found the remnant of the Larsen B Ice Shelf is flowing faster, becoming increasingly fragmented and developing large cracks. Two of its tributary glaciers also are flowing faster and thinning rapidly.

"These are warning signs that the remnant is disintegrating," Khazendar said. "Although it’s fascinating scientifically to have a front-row seat to watch the ice shelf becoming unstable and breaking up, it’s bad news for our planet. This ice shelf has existed for at least 10,000 years, and soon it will be gone." Read More.

#Greenland Permafrost Melting Faster Than Snowball In Hell

Why This New Study On Arctic Permafrost Is So Scary

Scientists might have to change their projected timelines for when Greenland’s permafrost will completely melt due to man-made climate change, now that new research from Denmark has shown it could be thawing faster than expected.

Published Monday in the journal Nature Climate Change, the researchshows that tiny microbes trapped in Greenland’s permafrost are becoming active as the climate warms and the permafrost begins to thaw. As those microbes become active, they are feeding on previously-frozen organic matter, producing heat, and threatening to thaw the permafrost even further. Read More  

Melting Faster Than A Snowball In Hell

Think of it this way, as the ice melts so does the air conditioning capacity of the planet. There is a point of no return when this process can not be reversed making the fate of all matters assured. 

Metrics on ice can therefore provide  a fairly accurate measure of life capacity and can be modelled to determine timelines. Timelines remember that will articulate exponential speed near the end. 

No further words required.

Catastrophic Collapse of West Antarctic Ice Sheet Begins

– The biggest glaciers in West Antarctica are hemorrhaging ice without any way to stem the loss, according to two independent studies. The unstoppable retreat is the likely start of a long-feared domino effect that could cause the entire ice sheet to melt, whether or not greenhouse gas emissions decline.

"These glaciers will keep retreating for decades and even centuries to come and we can't stop it," said lead study author Eric Rignot, a glaciologist at the University of California, Irvine, and NASA's Jet Propulsion Laboratory in Pasadena, Calif. "A large sector of the West Antarctic Ice Sheet has passed the point of no return." [Vanishing Glaciers: See Stunning Images of Earth's Melting Ice]

The West Antarctic Ice Sheet holds 10 percent of Antarctica's ice. Glaciers here sit in a giant bowl, with their base below sea level, making melting a concern since the 1970s. As the ice retreats into the bowl, it shrinks back into deeper water, making the glaciers unstable. Like frozen levees, the retreating glaciers pin back more stable parts of the Greenland-size ice sheet. Their collapse threatens the entire West Antarctic Ice Sheet. 

Two papers published today in the journal Geophysical Research Letters and Science used different approaches to forecast the future of West Antarctica's shrinking glaciers. One study tracked the region's biggest glaciers for 40 years, and concluded from direct observations that the ice is unstoppable. The other relies on sophisticated computer models to predict the future melting of Thwaites Glacier, the biggest of West Antarctica's frozen ice rivers. 

Both studies conclude that even dramatic changes in climate won't stop the retreat, because the glaciers are shrinking back into deep valleys with no ridges or mountains to halt their rapid pace. Any high topography can act like a speed bump and slow the galloping glaciers.
