Fastest-thinning Greenland glacier actually growing thicker instead of shrinking



The fastest-flowing and fastest-thinning glacier in Greenland, Jakobshavn, is losing less ice than expected, and is actually growing thicker rather than shrinking. Scientists believe the unusual activity is due to colder ocean currents caused by a natural climate pattern known as the North Atlantic Oscillation, which makes the northern Atlantic Ocean slowly switch between warm and cold water about once every 20 years.
