Big, big changes this month, and not for the good. Due to extremely high, or maybe I should say non-low temperatures in the Arctic the past month, this new year opens with the smallest monthly volume increase for January in the 2006-2016 record. 2007 saw an increase of 2848 km3, but 2016 goes one better with 2794 km3, in all other years volume went up by more than 3000 km3.
This means that, yet again, current volume has crept closer to the post-2010 years and widened the gap with pre-2010 years. Below the change in difference between January 1st and 31st is shown:
On January 31st 2016 the Arctic has just 104 km3 of sea ice volume than the same date in 2012, the year of the record melting season. The difference with 2013, the year that followed the big melting season, is still 803 km3, but it has gone down by 920 km3 in just the past month. The difference with last year (when two rebound years caused a marked increase in volume) has changed to a whopping 1692 km3. 2016 is still in 4th position, just like last month, but the gap with the top 3 has diminished radically. I could go on. Really big changes.
On Wipneus' version of the volume graph we can clearly see how differently the 2016 trend line moves from other trend lines around it:
