Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center:
During February Arctic sea ice volume increased by 2075 km3, according to the PIOMAS model, which is well below the 2007-2017 average of 2437 km3. Only 2014 and 2016 managed to score lower, at 1930 and 2047 km3 respectively. This means that 2018 has consolidated its second place in the ranking, creeping somewhat closer to 2017. Especially the gap with 2013 has widened spectacularly from 166 to 1261 km3. Closest follower is now 2011 at 817 km3.
Wipneus' version of the PIOMAS graph clearly shows how the 2018 trend line strongly deviates from all the other trend lines during February:
