Seth Borensteinh, Arctic sea ice 6th lowest, but rebounds from 2012 Bloomberg Businessweek News (September 20, 2013):
"The National Snow and Ice Data Center in Boulder, Colo., said Friday that Arctic ice was at 1.97 million square miles when it stopped melting late last week.
"That level is about 24 percent below the 20th Century average, but 50 percent above last year when a dramatic melt shattered records that go back to 1979."
Hannah Hickey, Stronger winds explain puzzling growth of sea ice in Antarctica University of Washington News (September 17, 2013):
"Much attention is paid to melting sea ice in the Arctic. But less clear is the situation on the other side of the planet. Despite warmer air and oceans, there’s more sea ice in Antarctica now than in the 1970s – a fact often pounced on by global warming skeptics. The latest numbers suggest the Antarctic sea ice may be heading toward a record high this year.
"While changes in weather may play a big role in short-term changes in sea ice seen in the past couple of months, changes in winds have apparently led to the more general upward sea ice trend during the past few decades, according to University of Washington research. A new modeling study to be published in the Journal of Climate shows that stronger polar winds lead to an increase in Antarctic sea ice, even in a warming climate."
