The large number of observations you cite are only over a period of the past 126 years. If, as you infer, a large number of observations lends more validity (which I do agree with, by the way), then take this back to include climatological information on geologic time frames, and compare, for example, this recent warming with the last similar period in Earth's history. I do not recall how long ago it was, but it was cited in a recent presentation made at my University on this very topic. If you could show, for example, that this warming is occurring at a faster rate than the last one, that would be significant.
If you perform the analysis you suggested, the trendline correlation coefficient is 0.1443. I may not remember much from my college statistics courses but I do remember that such a low number signifies very little statistical confidence or relevance.
