Professor Ole Humlum, based in Svalbard near the Arctic Circle, has a trove of climate data at his website Climate4you. This includes a graphic of the cumulative graphic technique applied to the HadCRUT series of monthly global average surface air temperatures. It is found half way down this page, entitled ‘Cyclic air temperature changes’.
The changes of trend evident have no apparent correlation with any solar data series including the solar cycles, both Hale and Schwabe. I was rereading a book I wrote in 2014 entitled Twilight of Abundance for a new polemic when I came across this paragraph on page 14:
