But doesn't quite convey that the extent/area record isn't everything -- it's still going down. Here's one commonly cited source of many:

The gifs of the time series here give some sense of the evolution since the 80's:

There is a product, PIOMAS, that also produces the arctic sea ice volume with some delay (the data are sparser and it has to be partially modeled) -- arctic ice that has been around for more than a year tends to be thicker; you can lose a lot of volume before you lose a lot of area. Think of frozen lakes in the spring. Here are some plots -- note that the y axis starts at zero, but you have to be a little wary of those mathematical extrapolations. On the third hand, the physically-based expectations are now off by, oh, several decades:
