Just like last month the 2015 trend line has increased the gap with pre-2010 years, with the exception of 2007. It has also crept closer to 2014 (difference now 631 km3, down from 1208 km3 last month), but the difference with 2013 has increased by 225 km3 to 1223 km3. According to the model the difference in volume with top 3 years 2010, 2011 and 2012 has grown by 538, 333 and 1063 km3 respectively. As of the end of June there is 2968 km3 more ice than at the end of June 2012.
The differences are more clearly visible on Wipneus' PIOMAS volume graph:
