"One of the largest glaciers in Antarctica is thinning at a rate four-times faster than just a decade ago, researchers said Friday. Researchers at the University of Leeds, writing in the journal Geophysical Research Letters, said the Pine Island Glacier in West Antarctica is thinning at a rate of up to 16 metres a year and has lowered as much as 90 metres in the last decade.

At its current rate of thinning, the glacier could disappear in a century. Previous predictions, based on the glacier's rate of decline a decade ago, said the glacier would likely disappear in 600 years. The Pine Island Glacier is the largest glacier in West Antarctica, and at 175,000 square kilometres is roughly the size of the province of New Brunswick and the island of Newfoundland combined."
