Comparisons are made between three climatic data sets consisting of Northern Hemispheric annual surface air temperature departures over the past 100 years. It is shown that despite the large values of linear cross‐correlation between the data records, the long‐term trends are significantly different according to the bootstrapping procedure. The confidence of relying on any particular data set for assessing global climate change statistics is thus questioned.
