Assuming their data is correct, 23 sites is not exactly the whole of the Arctic, and 0.2 degrees per thousand years is so near zero it doesn't matter. With the last ice age ending only 10,000 years ago +/- 1000 years or however long it took to defrost, that suggests their sample sites were places near the periphery of permafrost which were about to flip over to defrosted, which would be a phase change with the associated major temperature changes.

Even if it's really good data, really balanced and so on, there is the question of correlation and causation. Leaping from a temperature rise to CO2 as the cause is hardly robust reasoning.

Further research and therefore lots more lovely money is needed for them to continue their fun.

Let's see photographs of their 23 sites and show them on a Google Earth map too so we can zoom around and see why them might have chose them and decide if the locations might represent the Arctic in a partly reasonable way.
