Spot The Difference

June 24, 2014

The above two graphs are half-century plots of HADCRUT4 global temperatures. Both use exactly the same time and temperature scales.


Which one is 1895-1945 (Nature’s fault), and which is 1963-2013 (Your fault)?

    Give us a clue?

    Is it not possible to illustrate both series side by side with their respective trend lines?

    Setting them on separate y-axis would eliminate the absolute temperature differences.

    From the HadCRUT4 data, I calculate that one of those series warms at quite a faster rate than the other, but I’ll not say which…..

    The first one is my fault.

    The second one is Gaia’s fault.

    The first one is 1965 to 2013. The 1998 super Elnino gives it away.

    You don’t need that to tell the difference. The shape of the curves tell you that; but I smell a ringer. Well not quite. They don’t quite match rotated and inverted; but it is interestingly close.

    Of interest is what must have happened in the period between 1945 and 1963 irrespective of which is which.

    The first graph is the most recent as it shows the “pause” from 2000-2013.

    I think you nailed it.

  3. New paper claims the ‘pause’ is ‘not so unusual’ & ‘no more than natural variability’ | ss_site_title
