The deseasonalized monthly mean surface temperature time series for Nuuk, Greenland in the 148-year sample period 1866-2013 shows a statistically significant OLS warming trend of 0.1C per decade. Rescaled range analysis of the deseasonalized and detrended residuals reveals a high value of the Hurst exponent indicative of memory, dependence, and persistence in the time series. A robust test for trends described in a previous paper (Munshi, 2015) indicates that the observed OLS trend in the Nuuk data is spurious and therefore possibly an artifact of dependence and persistence.
