Arctic Sea Ice Extent has actually climbed 130,000 sq km over the last few days. Extent is now inside the one standard deviation mark again (by about 1000 sq km).
DMI’s temperature has been oscillating up and down but is sort of approaching normal.

I have been following the ice extent reports from MASIE, who showed day 73 as this year’s maximum. They include satellite imagery and operational data along with microwave sensor results, so the amount of ice extent is different. Usually the numbers are close at the annual maximums, but MASIE will show much more ice than the others in the summer.
I can also observe that since the max on March 14, MASIE shows increases in ice extent in the Central Arctic and the highest extent there was the last report dated April 5.
For comparison for previous years, MASIE shows these NH ice extent Maxes (in MKm2):
2014 15.52 March 14
2013 15.64 Feb. 28
2012 16.10 March 04
2011 15.38 March 18
2010 15.92 March 14
2009 15.91 March 08
2008 16.04 March 24
2007 15.81 March 15
Thanks for info Ron.
And because I was curious about the future, here are the MASIE ice extent minimums back to 2007:
