The study suggests that ice sheets such as those covering Greenland can quickly react to short-term climate shifts, said lead researcher Nicols Young, a postdoctoral researcher at Columbia University's Lamont-Doherty Earth Observatory.

This actually says only that glaciers can GROW fast in the proper conditions. Nowhere does it show that they can react fast to WARMING.

Arctic sea ice, either by satellite or submarine data, is above the 2007 and 2011 Arctic sea ice extent AND, a month later than 'normal', the sea ice average for the decades of 2000's, AND THE 1990's, at 8,704,063 km2 (November 14, 2012), again, a bit larger than W.Virginia, with average temperatures above the 80th parallel chilling to -20 degC. The sun has been unseen from the North Pole for 8 weeks!
Arctic Ocean warmth is & will continue to keep Arctic sea ice thinner through the coming winter & even spring. As of October 2, Arctic sea ice VOLUME is ~23% lower than any satellite recorded year AND indications of submarine-detected Arctic sea ice yearly VOLUME.

Presently, Arctic sea ice extent is 300,000+ km2 less than 2nd place 2011, at 8,813,750 km2 (November 15, 2012), not surprisingly bumping up by the size of Virginia. Present temperatures on landforms surrounding the Arctic Ocean, have numerous areas, like Siberia & Arctic Canadian islands to the deep minus twenties & even to -33 & -34degC. Finally, the Arctic Ice Pack has attached solidly to the north coast of Alaska. If a circulation pattern that just developed north of the Being Strait remains, could further southward icing occur, along the western coast of Alaska? Baffin Bay is sea icing. Due to solar heats absorbed into the shallow waters of Hudson Bay, despite many sporadic temperatures to as low as -24 degC, the Bay still has NOT ICED.
The vast open Arctic waters north of Siberia have been covered by Arctic Ice Pack. The huge sea ice floes that strongly developed in the vast clear waters north of Siberia(due to broad double digit minus Siberian temps spilled from North Pole's 7+ weeks of darkness & vortex mixing breaking down stratified solar heated waters?), have done their job AND connected the Ice Pack to the entire Siberian coastline, truly a remarkable past development!
However, Franz Joseph Land & Svalbard, in winter darkness 24/7, are still clear of the Ice Pack!!!!!!!!!! A circular vortex formed north of the line connecting both sets of islands. Wonder if the Ice Pack may expand in this area?
The vortex has quickly moved over towards the east coast of Greenland & may or may not assist the south moving flow of Arctic cold water.
The vortex HAS HELPED the south moving flow of Arctic water & extra sea ice broadening is evident along the east coast of Greenland.
A detail noted a month ago, is a raggy taggy developing edge along a part of the semi-circle Ice Pack, possibly NOT coincidental with the HUNDREDS OF THOUSANDS (plus?) OF SQUARE KILOMETERS, of waters north of Alaska & Siberia that are VASTLY CLEAR. Might the raggy taggy edge indicate huge turbulence & currents in this largest(ever?) ice free, & resulting southerly-directed heat stratified Arctic waters? I wonder if there might develop more raggy taggy edging, enough to form a swirl pattern?
Almost a month ago, noted near the raggy taggy Ice Pack, developed 3 tiny pixel ice floes(arced?), separated from the Arctic ice pack toward southerly directions. Four weeks ago, the number of ice floes increased to 8 & indeed they formed an ARC. Pretty sure they represent a large scale vortex in open Arctic water!
Further data, showed that the vortex was true!
Downwelling solar heats, in unusual clear Arctic Ocean & seas, normally sea ice covered in decades past, which have strongly transported extra solar energy to continental shelf, sea & Ocean depths for 4 months, is over. The sun has been unseen from the North Pole for 8 weeks & presently anywhere above the 72nd parallel, now shrouding the Arctic with darkness for a good portion of the year! The Northwest Passage is in darkness 24/7. Only far north European, & far western Russian southern Arctic seas get a skimming from the sun for only a bit of the day, which is visually less than a two degrees off the horizon, at its highest!
