Interesting graph Cam, even with out the "ajustments" at the swing in temps over the time frame measured.
It would be interesting to see a graph of temps that shows the change from month to month. I remember growing up that it used to get colder earlier (Sept./Oct.) in the year and warmer sooner (Mar./apr.) compared to current years. It seems the temp change has shifted to later in the year. You tend to notice that as a kid living on the beach.
Then compare to your posted graph. I believe climate change is a natural swing. But for those of you that would like to buy some carbon offsets let me know.
