First Differences

Over at Climate Audit, Hu McCulloch as a guest post The First Differences Method that describes a simple way to calculate the global surface trend from station data. This method turns out to be same as the Integrated Derivative Method we describe in our Climate Analysis essay. I said as much in the comments of Hu's post, and pointed to our Continuous Stations plot, which we generated with our Integrated Derivative Method.
