Ice Outlook from National Snow and Ice Data Center

This is a quote from the NSIDC which leaves some speculation as to what is taking place up here this summer. Sounds similar to my 2007 success on Cloud Nine but less rapid breakup of the ice. What will we see?

The Arctic is now in the midst of the summer melt season. Through most of June, ice extent tracked below the 1979 to 2000 average, and slightly above the levels recorded during June 2007. Warm temperatures and southerly winds led to quickly declining ice concentration in some regions, such as the Laptev Sea.

The contrast between high and low pressure is broadly similar to the atmospheric circulation pattern that set up in 2007. In 2007, that pattern contributed to a significantly accelerated decline in ice extent during July, and a record minimum low in September. Will the same acceleration in ice melt occur this year? If so, a new record low minimum extent becomes more likely. So far, an acceleration has not been observed. As July progresses, the Arctic sun gets lower on the horizon, incoming solar energy decreases, and the chances of such a rapid decline become less likely.
