Yeah, I did.

Most convenient? What the hell does that mean?
I think the term you're looking for is stabilizing selection.

Their size wasn't changing. Their bodies simply could not cool themselves efficiently.

Nobody really lived in those conditions. Please understand that. People retreated to refugia--Cro Magnon, Neanderthal, Denisovan, the first Americans. You know about Meadowcroft. It's 16,000 years old and may be 19,000. But the glaciers never got that far south. They stopped in your backyard.
People were not equipped, either physically or technologically, to deal with the worst of conditions. For a long time it was thought that the Neanderthals were cold-adapted. Not true. They were adapted for warmth just as Cro Magnon was.

That's BS. You're saying that humans, from the evolutionary inception, were 8 feet tall. There is absolutely nothing to support that.
Please, Duane, let's deal in reality here.
