-Red line R^2 for year Y to Y=2000.

e.g: say correlation CET-SSN for CETs and SSNs records from 1830 - 2000

-draw a vertical line from 1820 to intersection with the red line reading R^2 = 0.3 for that period, which is about average all the way 1900, but still not significant enough. From around 1900 - 2000 CET-SSN correlation is just not worth mentioning.

-Magenta line R^2 for Y to Y+100 years.

is for any 100 year period, hence as in the above example CET-SSN correlation would be for period 1830 -1930. Using same vertical line, it shows R^2=0, i.e. CET-SSN records correlation for period 1830 -1930 = 0.

Correlation is calculated for every single starting year for both:

1. gradually diminishing period to 2000, starting at 1670 up to 1970, the last correlation entry is for period 1970-2000.

2. sliding 100 year period ending at 1900, the last entry is 100 year correlation for records up to 2000

It is first time that anyone has reproduced such graph, which may be of some concern to any hypothesis which suggests that rise in the CET is due to solar activity as demonstrated in the available SSN record .

 

GRAPHIC OVERVIEW

 

-Blue line is the CET anomaly (reference average value from 1659-2010) from UK met office data file (11 year r.m. or moving average)

-Orange line is the integrated sunspot number (from 1620as available -2010) and subsequently normalised to CET (note SSN can not be <0, although it is plotted as such for a clearer visual reference).
