Large parts of West Antarctic Ice Sheet could collapse 'in our lifetimes'


Scientists say they discovered the “troubling” reason why a massive iceberg splintered off one of West Antarctica’s largest glaciers last year, and why this may not bode well for the future of the world’s coastal megacities.

Warm ocean waters appear to have melted Pine Island Glacier from underneath, causing a deep subsurface crack that split the ice from the inside out, Ohio State University researchers found.

The 20-mile-long rift eventually broke through the surface and cleaved off a 225-square-mile iceberg in July 2015, according to their study, published Monday in the journal Geophysical Research Letters. Read more…
