I am glad I live near a nuke plant.
Are you sure that nuke plant isn't on top of a burial ground?
Within the last few years sunspot activity has been minimal, more so than at other such periods. Usually things get active on Earth at those times.
Regarding climate, historically civilizations tend to flourish during warmer climates. When the temperatures drop, it gets more difficult for people reliant on that warmer climate. During the 8 centuries of the Roman Republic then Empire, Rome was on thhe upswing when it was warmer and on the decline when it was cooler. It may have been the same with Ancient Egypt, but I don't know enough to say either way.
As much impact as humanity has on the climate, forces far greater than humanity influence climate in ways we can't even begin to imagine.
