One method would be to subtract year from year and classify the
resultant raster as a delta temp map (values around 0 being no
change, larger changes being classified with warmer or cooler
temperatures). Alternatively, find the mean value of the
dataset: raster1+raster2+raster3...raster(n) / n. Reclassify
each as to a function of being above/below mean.
