This is just not correct.

There’s a 10,000 year period from the exit of the last ice age to about the year 0 where global temperatures were at least as warm as the 1960-1990 average. For a maybe 6000 year period within that global temperatures were about a half a degree or a little less warmer than that 1960-1990 average.

You’re just wrong. Before greenhouse gas emissions took control there’s a well recognized pattern of slow global cooling over a few thousand years.
