Antarctica
Walking on Thin Ice
A new satellite study conducted at the University of Leeds, reveals Antarctica’s massive potential contribution to rising sea-levels. Antarctica contains a large amount of submerged glaciers on the “grounding line,” the location where ice, sea, and bedrock meet. The rise of water temperatures has contributed to the grounding line moving closer to the shore, as glaciers rapidly melt and fall into the ocean. About 10.7 percent of Antarctica’s grounding lines are retreating closer inland at a rate of 25 meters a year; a rate that hasn’t occurred since the end of the last ice age. Antarctica has the potential to raise sea-levels by 200 feet. The study revealed, that with Antarctica’s 10,000 mile stretch of coastline, about 80 miles of ice could be dislodged from the seafloor between the years of 2010 and 2016.
