OP:
I recall NASA predicting complete loss of arctic sea ice by 2013, and the navy predicting the same in 2016.
You:
after reviewing his own new data, NASA climate scientist Jay Zwally said: "At this rate, the Arctic Ocean could be nearly ice-free at the end of summer by 2012, much faster than previous predictions."
US Department of Energy-backed research project led by a US Navy scientist predicts that the Arctic could lose its summer sea ice cover as early as 2016 - 84 years ahead of conventional model projections.
Are you unable to see the difference?
One NASA climate scientist said "the Arctic Ocean could be nearly ice-free at the end of summer by 2012", not "NASA predicted complete loss of arctic sea ice by 2013".
As it happened we hit the lowest sea ice extent since 1979 in September 2012.
A US Navy scientist predicted that "the Arctic could lose its summer sea ice cover as early as 2016", not "the Navy predicted complete loss of arctic sea ice by 2016".
As it happens we're currently only just inside 2 std deviations of the average, looking much like 2014 and 2013.
