What I am finding difficult to understand is the one time correlation between Earth mean temperature and the frequency of sun spots. At one time it was 'proven' with long term data that Earth temp increased whenever sun spots appeared but that well established belief is somehow no longer relevant.
I've just seen graphs showing a considerable declining occurrence of these spots over many years but it's studiously ignored by the evangelists. Odd, that.
Try: sidc.be/silso then select 'number of spotless days vs. Solar Cycle' in dropdown
(Royal Observatory of Belgium 2020 Jan). Seems a worthwhile source to be trusted by 'deniers'.
