The thing about global temperatures is, they're global averages. Weather is variable, and local weather even more so. Statistical outlier months at individual locations or even statistical outlier YEARS GLOBALLY, mean NOTHING. When you're looking at a 2-3 degree trend on a global average over at century long time frame, looking only locally or over time periods less than a decade the signal to noise is too small to measure with any accuracy.
If I shrink my time domain only a couple orders of magnitude further, and use my house as the single location for the global measurement, I'd say starting around 4PM yesterday we were in a serious global cooling situation, and had it continued at the 4PM till midnight rate we would be well into the next ice age by Tuesday, and by next month we'll be at absolute zero. But between 6-9 this morning the trend flipped- looks like we have until early Wednesday afternoon before all of the water on earth will boil away.
That's ridiculous, of course, but no more ridiculous than using this season's weather in Seattle or NH as reference points for 100 year temperature averages of a few degrees, global in scope.
Weather is highly variable- count on it, and even a decade average would be close to the minimum time scale on which any information at all on the century scale trend would be relevant, and only with a very spatially diverse set of data collection locations. With the right filters applied to a diverse data set the global-weather signal-to-noise is quite tame-able (a more straightforward problem than the signal-to-noise filtering that allows your cell-phone to work.) It's not all BS- the trends are measurable, and the evidence is a distinct warming trend (of which we have barely more than order-of-magnitude precision), whether or not the proximate causes are all well understood.
The weather last week/month/year/decade in Schenectady or Timbuktu has no relevance in isolation, and to use things like that a reference point for confirming 100 year global trends is about as smart as my using the rapid temperature drop at my house last night as evidence of extreme global cooling.
But y'all knew that.
