Alaskan Glaciers are Melting and Adding to Sea Level Rise

In Alaska unprecedented heat is melting glaciers and causing sea levels to rise. According to a new study the amount of water from melting glaciers could cover the entire state of Alaska in a foot of water every seven years. This is the finding of the authors of a study called "Surface melt dominates Alaska glacier mass balance," published in the peer-reviewed Geophysical Research Letters, a journal of the American Geophysical Union.

Antarctic Glaciers Pass the Point of No Return

A recent report concludes that Antarctica's ice sheet has reached a tipping point from which it will not be able to recover. Scientists predict that the glaciers in the western part of Antarctica will melt and raise sea levels by four feet or 1.2 meters. These sea level rises will displace tens of millions of people from coastal areas around the world.

As explained by NASA glaciologist Eric Rignot, the glacial retreat "appears unstoppable." Rignot is the lead author of a joint NASA-University of California Irvine paper that used 40 years of satellite data and aircraft studies to come to the conclusion that Antarctic glaciers are now "past the point of no return."

The rate at which the area's ice is melting has increased 77 percent since 1973. According to researchers the melting is being precipitated by warmer ocean currents which have begun a chain reaction. Although first observed around glaciers in the Amundsen Sea-area, the effect is expected to spread to other Antarctic glaciers.

Video - Watch the Disintegration of the Largest Glacier Ever Recorded on Film

Glaciers are melting at an ever expanding rate all around the world and this video documents the disintegration of the largest glacier ever recorded on film. This glacier has ice spires that are two or three times taller than the tallest buildings in New York City. In the last ten years it has retreated more than in the previous century.
