This animation shows the 2012 time-series of ice extent. The black area represents the daily average (median) sea ice from 1979-2000. Layered over are the daily satellite measurements from January 1 — September 14, 2012. A rapid melt begins in July, whereby the 2012 ice extents fall far below the historical average.
This melting has caused many to reconsider their predictions. A Cambridge scientist in the Arctic believes we could be only 4 years from a North Pole without ice.
Peter Wadhams, who heads the Polar Ocean Physics Group at the University of Cambridge and who has measured Arctic Ocean ice thickness from British Navy submarines, says that earlier calculations about Arctic sea ice loss have grossly underestimated how rapidly the ice is disappearing. He believes that the Arctic is likely to become ice-free before 2020 and possibly as early as 2015 or 2016 — decades ahead of projections made just a few years ago.
No, this picture doesn’t show a black and white image of the rebel base on the ice planet Hoth. It’s part of a semi-secret, nuclear-powered U.S. Army base that was built under the Greenland ice cap only 800 miles from the North Pole. The base was officially built to conduct scientific research but the real reason was apparently to test out the feasibility of burying nuclear missiles below the ice under an effort known as Project Iceworm.
Remember, Greenland is way closer to Russia than the ICBM fields located in the continental U.S. Rumor has it that the Danish government had no idea that the U.S. was considering installing nuclear missiles on Greenland.
The base was massive, described by some as an underground city, and consisted of 21 steel-arch covered trenches; the longest of which was 1,100-feet long, 26-feet wide and 26-feet high. These tunnels contained numerous prefabricated buildings that were up to 76-feet long. The base was powered by a portable PM-2A nuclear reactor that produced two megawatts of power for the facility.
“The camp was staffed year round, with population peaking at nearly 200 over the summer months.”
