It appears that the largest Arctic glacier, the Petermann glacier in Greenland, is about to get a bit smaller. Reports from scientists monitoring the situation indicate that a chuck of ice the size of Manhattan (100 sq. kilometers) is about the fall off, with the suspected cause being at least partially to do with increasing flows of warm water moving up the coast due to the region's changing climate, New Scientist reports.Large chunks of ice break off the Petermann glacier all the time, but with a chunk this size breaking away--this 5 billion tons of ice is about half of the glacier's annual flow--it's unlikely that current rates of snowfall elsewhere on the glacier will be able to make up for it.
Scientists expect the ice chunk to fall off within the coming weeks.
