Didn't the global warming known as the end of the last ice age begin about 8000 years ago?

It would make sense that major cities of that time would have been built on coastlines -- long since flooded.

We need to restore the earth to its natural ice age condition.

Yes! Many underwater cities are waiting to be found.
