Nonsense. It shows that our entire fabric of society sprouted and flourished in a climate that was incredibly stable and predictable. Yes climates have shifted, but not with complex human societies around. The chart also shows very clearly how the recent jump in temperature corresponds to industrial scale burning of fossil fuels.

Climates change, but if it happens fast, shocks can ruin societies. We humans made it go fast. Anyone denying the overwhelming amount of evidence just doesnt want to change his or her ways, and doesnt want to do anything to force the higher ups to change.
