There have been several already. The last one ended about 15,000 years ago.
This interglacial period has lasted longer than most of the previous ones.
We’re overdue.

The earth has spent more time frozen than it is like now.

I have learned in history class 63 years ago only about one ice age and that was the one 15,000 years ago.

Don't tell me you are falling for this crap about more ice ages.
