With the anthropogenic perturbation likely to be around 2C and maybe more in the next 100 years (that's a global average, it will be much more over northern hemisphere land where we actually live), there are simply no comparable sources of natural variability, and the historical record shows that such temperatures have not been approached in the last 2000 years.

The analysis shows that the rise in average world land temperature globe is approximately 1.5 degrees C in the past 250 years, and about 0.9 degrees in the past 50 years.

Secondly, since the ocean warming is shown to be consistent with the land surface changes, this helps validate the surface temperature record, which is then unlikely to be purely an artifact of urban biases etc..

Bickmore's own graph showing the temperature anomaly results had actually landed outside the ball park before dribbling back in demonstrates that the bulk of the IPCC scenarios are in the upper extreme and the modelling used should be reconsidered.

As I said before with exception of GISS, the other four organizations who measure global temperatures [land + ocean] show the same cooling trend from 2002.

I went ahead and plotted the normalized (HadCRU + GISS) / 2 --(RSS + UAH) / 2 to show the variance between satellite and land - based temperatures.
