Colorado Surface Temperatures, 1775-2011

Using the Berkeley Earth Surface Temperature (BEST) data here, the following plot was created. It represents regional climate change for the State of Colorado. The plot shows the mean monthly surface temperature, the mean daily maximum surface temperature, and the mean daily minimum surface temperture. Compare the plot below with that provided here based on the same underlying data.

Colorado is home to a large community of climate modellers (The Boulderians). How do the results of climate models relate to the BEST actual surface temperature data shown here? That is certainly one question that needs a serious answer from the modellers….not just hand-waving. More work is needed to examine the BEST data and algorithms, but this first cut suggests that the people sounding alarms over an impending climate catastrophe are in a world of their own. The historical record suggests a very broad yet defined band of highly variable temperatures. This might be more apparent if the actual data is plotted rather than mean values. We’ll work on presenting that in the future, as it will take some time to dig through the BEST data set. The data for the graph below (and the others I have posted) are the means calculated by BEST.
