Subject: [Phys-l] Arctic sea ice 'faces rapid melt'
The average sea ice extent for the entire month of September this year
5.9 million sq km (2.3 million sq miles). Including 2006, theSeptember
rate ofkm
sea ice decline is now approximately -8.59% per decade, or 60,421 sq
(23,328 sq miles) per year.melt
At that rate, without the acceleration seen in the new modeling, the
Arctic
Ocean would have no ice in September by the year 2060.

Note the number above assumes a linear model But that's not the way
positive feedback systems work. According to some modelers the ice
could beSee
complete within 20 years with dire effects expected long before then.
