There are several scientific organisations that keep an eye on the Arctic sea ice cover and put out graphs to inform us of the amount of ice that is left. You can see most, if not all, of them on the ASI Graphs webpage. I expect the record on most of these graphs to be broken in weeks to come.
This is just a regional sea ice area graph put out by Cryosphere Today, but it happens to be the most important regional graph out there. This is the place where the last ice is expected to be if and when the Arctic is approaching an ice-free state. On this graph we clearly see the minimums for all the years in the satellite period (click for a larger version):
The data on this graph has been the source of a recurrent discussion on the ASI blog, revolving around the question: Was a plateau of around 2.3 million square km reached in 2007? This year might give us a clue. The trend line has already surpassed 2.25 million square km, but maybe things will level off now. Or it could dip below 2 million square km. We'll know in a few weeks, but either way, this is yet another record that was broken this year.
