TITLE:
Spurious correlations between recent warming and indices of local economic activity

AUTHORS:
Schmidt, Gavin

ABSTRACT:
I analyse a series of climate model simulations of the 20th Century to investigate a number of published correlations between indices of local economic activity and recent global warming. These correlations have been used to support a hypothesis that the observed surface warming record has been contaminated in some way and thus overestimates true global warming. However, the basis of the results are correlations over a very restricted set of locations (predominantly western Europe, Japan and the US) which project strongly onto naturally occurring patterns of climate variability. Across model simulations the correlations vary widely due to the chaotic weather component in any short term record. I find that the reported correlations do not significantly fall outside the simulated distribution and that the correlations are probably spurious (i.e. are likely to have arisen from chance alone). Thus, though this study can not prove that the global temperature record is unbiased, I conclude there is no strong evidence from these correlations of any large scale contamination.
