According to the JAXA satellite, Arctic sea ice extent peaked on March 8, 2011 at 13.89 M km2.
First, let's note that sea ice extent (akin to area) is not the absolute best measure of Arctic melting. That would be, of course, sea ice volume, which is modeled by PIOMASS.
But PIOMASS relies on modeling and is not a direct measurement, so some purists talk about ice extent.
This year, Arctic sea ice extent was lower than last year, and in fact, lower than any year since 2006:
Here the y-axis is in units of millions of square kilometers.
This is one way to look at the data. Here's another:
Which is best? Don't ask me -- deciding that is your job.
