Tipping point for polar ice cap may have come in 2012

This year may have granted a slight reprieve for vanishing Arctic sea ice, but evidence gathered to date shows that summer shrinkage will likely continue its downward spiral in future years, according to a new paper published in the Oct. 4 edition of the journal Geography Compass.
The paper, by Kent State University doctoral candidate Thomas Ballinger and Jeffrey Rogers, a geography professor at Ohio State University, synthesizes information about weather, ocean currents and ice conditions in the Beaufort and Chukchi seas between 2007 through 2012, a six-year period of severe melt. Conditions in those seas appear to have changed for good, the paper says.


“Dramatic reduction in late summer sea ice on these seas occurring in 2007 and subsequent years now appears to be a persistent and permanent feature of the summer Arctic environment,” it says.
