Arctic Sea Ice about to hit ‘normal’ – what will the news say?

Barring an about face by nature or adjustments, it appears that for the first time since 2001, Arctic Sea ice will hit the “normal” line as defined by the National Snow and Ice Data Center (NSIDC) for this time of year.

NSIDC puts out an article about once a month called the Sea Ice News.  It generally highlights any bad news they can find about the disappearance of Arctic ice.  Last month’s news led with this sentence.

In February, Arctic sea ice extent continued to track below the average, and near the levels observed for February 2007.

But March brought good news for the Polar Bears, and bad news for the Catlin Expedition and any others looking for bad news.  Instead of ice extent declining through March like it usually does, it continued to increase through the month and is now at the high (so far) for the year.

If it keeps this trend unabated, in a day or two it will likely cross the “normal” line.
