In order to understand the potential importance of the effect, let's look at what it could do to our understanding of climate: 1) It will have zero effect on the global climate models, because a) the constraints on these models are derived from other sources b) the effect is known and there are methods for dealing the errors they introduce c) the effect they introduce is local, not global, so they can not be responsible for the signal / trend we see, but would at most introduce noise into that signal 2) It will not alter the conclusion that the climate is changing or even the degree to which it is changing because of c) above and because that conclusion is supported by multiple additional lines of evidence, all of which are consistent with the trends shown in the land stations.

The hockey stick provides compelling evidence for the emergence of a human - caused warming signal from the background noise of natural fluctuations in climate.

Of course, on a timescale of one decade the noise in the temperature signal from internal variability and measurement uncertainty is quite large, so this might be hard to determine, though tamino showed that five year means show a monotonic increase over recent decades, and one might not unreasonably expect this to cease for a decade in a grand solar minimum scenario.

Nonetheless, even if the substantial recent trend in the AO pattern is simply a product of natural multidecadal variability in North Atlantic climate, it underscores the fact that western and southern Greenland is an extremely poor place to look, from a signal vs. noise point of view, for the large - scale polar amplification signature of anthropogenic surface warming.
