Environment – Pine Island Glacier (PIG), Antarctica’s fastest-melting glacier, is getting closer to losing a chunk of ice that’s 350 square miles – an area large enough to cover Manhattan, Brooklyn, Queens, Staten Island, and the Bronx combined, according to NASA.
While the crack itself is apparently normal for these types of glaciers, it is beginning to spread further upstream than what was indicated in earlier reports.
Glaciologist Ted Scambos of the National Snow and Ice Data Center (NSIDC) told National Geographic when “that point of rifting starts to climb upstream, generally you see some acceleration of the glacier.”
Acceleration of the glacier means that water will flow even quicker into the ocean contributing even more to the sea level rise. Changes in the Pine Island Glacier and other West Antarctic glaciers are important to note because they are part of the faster-flowing streams of ice causing environmental changes.
