'Dangerous' Antarctic glacier has a hole roughly two-thirds area of Manhattan

Huge Cavity Melted Out in Antarctica Glacier

Paul Beckwith

Total melt of west Antarctic glaciers would raise global sea levels about 5 meters; Greenland glacier melt would add 7 meters; east Antarctic plus mountain glacier melt would add 60 meters (total about 72 meters = 238 feet). I discuss how melt rates of Antarctica glaciers are rapidly increasing due to warm salty ocean water incursions under the ice; in fact under Thwaites Glacier in west Antarctica an enormous hole (about 4 km wide x 10 km long by 300 meters high) has appeared in only a few years.
