Climate Central reports

[...] A massive iceberg roughly 225 square miles in size--or in more familiar terms, 10 times the size of Manhattan--broke off [from the Pine Island Glacier] in July 2015. Scientists subsequently spotted cracks in the glacier on a November 2016 flyover. And in January, another iceberg cleaved off the glacier.

Satellite imagery captured the most recent calving event, which Ohio State glaciologist Ian Howat said " is the equivalent of an 'aftershock'" following the July 2015 event. The iceberg was roughly "only" the size of Manhattan, underscoring just how dramatic the other breakups have been.

[...] The ocean under Pine Island Glacier's ice shelf has warmed about 1°F since the 1990s. That's causing the ice shelf to melt and pushing the grounding line--the point where the ice begins to float--back toward land, creating further instability.

[...] The glaciers [such as the Pine Island Glacier] and ice shelves [such as the Larsen C ice shelf, which is on a death watch] help hold back a massive ice sheet on land. Their failure would send that ice to the ocean, pushing sea levels up to 13 feet higher than they are today.

[...] Cutting carbon pollution presents the only path forward to stave off the worst impacts of a melting Antarctic.

    It's because of Trump making Manhattan great again. ;-)
