Things just keep getting worse. After this year's trend line went well below all others last month, I was hoping January would bring some relief, some cold weather. The weather was cold, colder than November and December, but evidently not cold enough for some seriously anomalous ice accretion. And so the gap has widened.
According to the PIOMAS model, in the past 10 years, only twice before was there a January in which less than 3000 km3 of volume was added to the sea ice pack: in 2007 and last year. So, these are the only two years that didn't see the gap get wider. All the other years did.
2017 is currently 1571 km3 below the previous record lowest number for January 31st, which occurred in 2013 (the year following record smashing 2012). That's almost 10% lower.
Here's how the differences with previous years have evolved from last month:
And here's Wipneus' version, clearly showing the gap widening:
