More on Bart, FFTs and Cloud vs temperature

To me it seems that the plot has been lost on CA were discussions revolve around FFTs iFFT convolutions etc.

Is there a relation ship between cloud (Net_tot-SW_clr) and temperature or temperature and cloud?

How about a few simple plots:

The first uses data filtered with a Hodrick-Prescott filter of 1 and plots temperature anomaly against (Net_tot-SW_clr) sorted .
The second removes any filtering:

As can be seen the is a slight rising trend.

So now reverse the axis and plot cloud cover vs temperature anomaly (sorted) These are Duff!!

So there does seem to be a temperature and  (Net_tot-SW_clr) relationship. But which is the forcing????
