Antarctic ICE SHELF anticipated to break up this March - Not Good for our world

The Scar Inlet Ice Shelf will likely fall apart by the end of Antarctica’s summer, predicted Ted Scambos, a glaciologist at the National Snow and Ice Data Center in Boulder, Colorado. This inlet's ice is the largest remnant of the vast Larsen B shelf that is still attached to the Antarctica peninsula. One small fragment, the Seal Nunataks, clings on as well. In the Southern Hemisphere's summer of 2002, about 1,250 square miles of the enormous Larsen B Ice Shelf splintered into hundreds of icebergs. Scar Inlet is about two-thirds the size of the ice lost from Larsen B and it to is expected to shatter into thousands of pieces. This ice sheet formed over thousands of years as ice sheets and glaciers flow off the land and extend into the ocean to create a thick floating platform of ice. Scar Inlet ice shelf acts as a dam, holding back the glaciers. When this ice shelf disintegrates, it will unleash the glaciers ice and shelf ice at increasing rates into the ocean, which contributes to rising sea level.
The Scar Inlet Ice Shelf is decaying and is quite weak due to a relentless assault of manmade greenhouse gases. The ice is so thin and fractured that it just might collapse on its own, even without melting or a storm. Take a look at the photo above and note that the mélange consists of sea ice, icebergs, fast ice which means it is “fastened”  to the coastline, melt water, and snow in the bay which was once the mighty Larson B ice shelf. This mélange is all that is holding the rifts and fractures of Scar Inlet shelf ice from crumbling into the ocean.
