It is interesting to look at the mean Arctic Sea Extent for each month (for the last 10 years) all on one page.
The decadal trend is at the bottom of each graph. The dashed blue line is the linear trend. The green line is the loess trend.
January is dropping slightly, February is flat, March April and May are all climbing.
June is sropping but it has a major uptick from 2010.
July to September are dropping (but with an uptick at the end)
There is no data for Oct/Nov/Dec 2013 because of the shutdown. But all 3 will have an uptick for 2013.
