Goldilocks in the Bering Sea: Less sea ice is bad and more ice is bad

This article from yesterday about sea ice in the Bering Sea is priceless: while we are still being told that below average ice coverage (common 10-20 years ago) is a sign of global warming that means the end of polar bears sometime in the future, it turns out that too much ice is bad, less ice is friendlier and lots of ice is hopefully something that we’ll never see again.

From the article:

After a 2012 Bering Sea snow crab season that saw unusually severe sea ice inhibit fishermen’s efforts to catch almost 89 million pounds of the shellfish, 2013 is shaping up to be much friendlier.

According to Kathleen Cole, a forecaster with the National Weather Service ice desk, this winter was unlikely to match 2012, even before it began. Despite some recent rumors of encroaching ice into the Bering Sea fishery, the situation is better than last year, she said.

“We’re just not going to have a year like last year. It’s going to be, by no means, that bad,” she said. “Last year was something that we’d never seen before, and hopefully something that we’ll never see again.”

Sea ice is still well above average in the Bering Sea this year – as it has been for 7 of the last 10 years. See the ice extent map from NSIDC from yesterday below and my previous post from December 2012: Now that Bering Sea ice cover is high again, variability is normal (note that polar bears of the Bering Sea are considered part of the “Chukchi Sea” subpopulation, which we know practically nothing about, see previous post here).
