I agree with you that the last decade really doesn't tell you that
much about the long term trends, given the size of the error bars, but it does allow for some interesting analysis of the difference between individual temperature records during that period (e.g. ENSO responses of satellites vs. surface measurements, effects of different ways of treating arctic temperatures, etc.).
Canadian Ice Service: A single partial - recovery year in terms of summer sea ice extent has no implications on its own — it might simply be the result of interannual variability or
noise about the longer term trend.
«decadal fluctuations are too large to allow us to make decisive conclusions
