The Scythian culture started at lease 6 or 800 BCE, and the culture had pretty much died out before the time of Christ. So obviously the Roman Climate Optimum and Medieval Warm Period were not warm enough to cause the melting of their tombs and rotting of the corpses that scientists are rushing now to save. It would appear that our “global warming” is warmer than some of the earlier warmings.
There’s no evidence of that, even in the article. The author does beat the drum a lot though.
