from the world's big
This is doubly worrisome on the heels of the recent UN climate change report, which gave humanity an urgent deadline to cut carbon emissions: just 12 years.
- It's the same glacier that calved in September 2017, losing an iceberg 4.5 times the size of Manhattan.
- The size of this one, however, is about 15% bigger than the last. It's the sixth large-calving event from this glacier since 2001.
- The irreversible collapse of the West Antarctic ice sheet would raise sea levels 20 feet, says the UN.

The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers.
