Does the rise and fall of nations correlate with climate change?

Here is something interesting to think about:

Indeed, I was listening to a lecture by  Sallie Baliunas  and what she discovered from the ice core samples obtained from the North Pole. She revealed that there was a 300-year cycle to the energy output of the sun which appeared in the ice core data. When I look at the cycle she revealed, I was stunned. It matched the 309.6-year cycle of the ECM. What I had discovered from the historical record of the rise and fall of nations that followed the ECM, suddenly I was confronted with at least part of the explanation – climate change.
