Evolution of the July correlation/regression coefficient at CO, GT, and SG and July mean temperatures between 1901 and 2002. July temperatures are averages between the three sites. The gray plot represents a 95 % confidence interval of a polynomial function fitted on July temperatures. The black dot locates the 1949 wildfire at GT. Under −2 line, the correlation/regression coefficients are significant at a threshold of 95 %
