Just so we're clear, I agree that tying a specific single event like this to a global phenomenon is not advised. Global warmings effects as 'proof' are really borne out by cumulative evidence, not a specific event such as a single forest fire or even a single bad year of forest fires.
Even if we can all agree that phenomena during a 10-15 year period are becoming more frequent, that doesn't necessarily prove climate change. The bigger question is, if we see a 10-15 year period of phenomena, can we expect this to revert back to a norm, or is it an indefinite change that is likely to not only not change but keep intensifying in the foreseeable future.
Based on all the meteorological and climatological data we're seeing, as well as observed 'tipping point' metrics, it would seem that the latter scenario - future intensification - is more likely. If I'm wrong and we revert back to 'normal', I'll happily admit it - I would be relieved, even. But the evidence doesn't seem to be giving us much reason for optimism.
