It has been this warm for about ten thousand years. Before that there was a hundred thousand year ice age. The previous warm period that lasted about ten thousand years was called the Eemian.
It would be natural to try to search for marks of civilization from the Eemian period.
But so far, only very simple stone tool artifacts have been found.
