Chris, it seems to me that it's a shame that you don't use google scholar ;-) The first link to the Swart et.al (20159 paper is the right one: http://re.indiaenvironmentportal.org.in/files/file/Arctic%20sea-ice%20trends.pdf Have fun!

LRC: The weather during the melt saison is for sure a factor for the amount of melting ice. Anyway, it's the elefant in the room? According to this: https://usclivar.org/sites/default/files/meetings/2014/amoc-abstract/ZhangR_AMOC2014.pdf the AMOC has a big influence on melting. And it's in decline... The "0" in the linked diagram is 18.000 km³, this was the amount of lost seaice in 2010 and 2012 which were (negative) outliner during 1979...2014 for march-september. My tip: september volume 2015 between 4.9 tkm³ ( melting just like 2010) and a bit more than 8.4 t km³ ( melting like 2014).

Bill, sorry 4 heart attack! :-) Indeed I used the "T" for 1000 km³. In German ( my native language) it's not unusual to use this big T for thousend :-). And yes, this was a hint to this: http://arctic-news.blogspot.de/2012/03/rebuttal-imminent-collapse-of-arctic.html , where a scientist used a central figure with an exponential trend... with it you can also show ( by extrapolating into the past) that the arctic was also ice free at about 1935... and nobody was aware of this :-) . Cheers Frank... with the best wishes 4 a long life... without heart attack!

The latest PIOMAS- data up to 31st of March 2015: http://fs2.directupload.net/images/150405/urn5hrnz.gif The center is 18 T km³ because the volume-loss between March and September was so big in 2010 and 2012. In the last year we saw a loss of about 15 T km³. So an ice free arctic seems to be very unlikely in 2015.

This figure shows the behaviour of the arctic sea ice volume (PIOMAS) as the relative anomaly vs. average of 2000...2013: http://www.dh7fb.de/noaice/vol13/volrel.gif Maybe it's more clearly presented than the figures in the post.

Chris, I don't full agree with you ( weather...). Let's habe a look at the Volume-data from PIOMAS ( monthly) and the trend of the autumn data from 2000 on. http://up.picr.de/20387070mj.gif . We see a slope of about -0.5 T km³ per year. Anyway, there is a great autocorrelation and so let's analyze the residuals: http://up.picr.de/20387095xe.gif . The data of 2014 are a 2.4-sigma-event. The seaice-volume of SON is only located in the Arctic ocean, so I thing that something happend beyond weather.
