Study: Key Antarctic ice shelf is speeding up its collapse Pine Island Glacier calves several new icebergs on Feb. 11, 2020, as seen via satellite. Photo: NASA Earth Observatory The Pine Island Glacier on the West Antarctic Ice Sheet is responsible for more than a quarter of Antarctica's contribution to global sea level rise over the past decades. Now, a new study shows it is more vulnerable to rapid melting than thought, because climate change is weakening its natural braking system. Why it matters: At stake is the future of a glacier containing about 160 trillion tons of ice, which if it were all to melt into the ocean would cause about 1.6 feet of global sea level rise.

Pine Island Glacier's ice shelf lost about one-fifth of its total area between 2017 and 2020, in three dramatic collapses. Meanwhile the glacier sped up by 12%. The rest of the ice shelf, the authors say, could disappear much sooner than previous studies had suggested.
For decades, the ice shelf helping to hold back one of the fastest-moving glaciers in Antarctica – Pine Island Glacier in West Antarctica – has gradually...
The Pine Island ice shelf - located on the West Antarctic Ice Sheet - has been known to have been thinning now for decades as a result of climate change.

Glaciers in West Antarctica are Moving Faster from Land into Ocean Written by AZoCleantechFeb 24 2021 A new study reports that glaciers in West Antarctica are moving into the ocean from land faster than ever, leading to increasing global sea levels. Image Credit: robert mcgillivray/Shutterstock.com Researchers used a 25-year record of satellite observations to demonstrate, for the first time, wide-ranging increases in ice speed throughout the Getz sector, where some portion of ice accelerated into the ocean by almost 50%. Led by the University of Leeds, the study describes that in the Getz region, 14 glaciers are thinning and flowing faster than ever into the ocean. From 1994 to 2018, 315 gigatonnes of ice had been lost, increasing the global mean sea level by 0.9 mm, which is equivalent to 126 million Olympic swimming pools of water.
