Trends in variability and autocorrelation in observed global temperature records

Figure 1Back in 2012, we started exploring how patterns in the magnitude and persistence of fluctuations in instrumental records of temperature and their major global sea and land indices might have changed during the last century. Our objective was to identify regions where climate variability and autocorrelation might have markedly increased potentially due to anthropogenic forcing. We just published the results of this work in a paper titled Observed trends in the magnitude and persistence of monthly temperature variabilityThe main findings are summarised here.
