Sunspot Cycle Length Correlates With Warming, Carbon Dioxide Levels Follow

The following graph comes from a website titled Friends of Science, here.
The graph shows that surface atmospheric temperature correlates closely with "sunspot cycle length", and not with increasing atmospheric carbon dioxide levels.

This supports the observations that warming causes carbon dioxide levels to increase, not the other way around. The data for this graph needs to be carefully documented and verified. Can anyone do this?

North Atlantic Sediments.....con't.

I found this almost immediately......hmmmmm.......where the heck is the carbon dioxide causing the warming coming from? Or could it be CO2 plays little if any role?

OXYGEN isotope measurements in Greenland ice demonstrate that a series of rapid warm-cold oscillations—called Dansgaard–Oeschger events—punctuated the last glaciation1. Here we present records of sea surface temperature from North Atlantic sediments spanning the past 90 kyr which contain a series of rapid temperature oscillations closely matching those in the ice-core record, confirming predictions that the ocean must bear the imprint of the Dansgaard–Oeschger events2,3. Moreover, we show that between 20 and 80 kyr ago, the shifts in ocean-atmosphere temperature are bundled into cooling cycles, lasting on average 10 to 15 kyr, with asymmetrical saw-tooth shapes. Each cycle culminated in an enormous discharge of icebergs into the North Atlantic (a 'Hein-rich event'4,5), followed by an abrupt shift to a warmer climate. These cycles document a previously unrecognized link between ice sheet behaviour and ocean–atmosphere temperature changes. An important question that remains to be resolved is whether the cycles are driven by external factors, such as orbital forcing, or by inter-nal ice-sheet dynamics.
