"What we found is that even within the discontinuous permafrost zone-the area where permafrost is warm and within a few degrees of 0C and shallow, only a few to tens of metres thick-it has survived at some locations for more than 700,000 years." Because of the potential longevity of the permafrost, it tells the story of climate changes over the course of hundreds of thousands of years, which Froese says is immeasurably valuable.

I found this interesting. I doubt it means anything regarding current climate theory, except that all of the permafrost didn't melt during the last several interglacials. It makes sense to me, either it didn't get as cold in those places, or something served as insulation (like the ground). What I find fascinating is the idea of finding even older remains than the one's we currently have.
