"Bottom Line – Using two back-of-the-envelope tests for significance against the CRU global temperature data I have discovered:
* 75% of the globe has not seen significant peak warming or cooling changes between the period prior to 1960 and the 2000′s which rise above a 0.5°C threshold, which is well within the CRU’s own stated measurement uncertainties o +/- 1°C or worse.
* Assuming a peak to peak change (pre 1960 vs 2000′s) should represent a change greater than 20% of the measured temperature range (i.e., if the measured temp range is 10° then a peak-to-peak change of greater than 2° would be considered ‘significant’) 87% the Earth has not experienced significant temperature changes between pre 1960 period and the 2000′s.
