The Ice Sheets Went Everywhere
When I lived in Tucson, Arizona, in the middle of the Sonoran Desert, I once talked to a colleague, who was enrolled as a student for an advanced degree in geography and climate, about the Ice Ages. I suddenly realized he was under the impression the ice sheets had gone everywhere in the Ice Ages, including Tucson, and maybe down to the Equator. I was going to ask about those happy days when humans frolicked with dinosaurs, but was afraid of his answer.

I have relatives in Tuscon
I asked some of them about dinosaurs. They told me they were hunted to extinction by man.

Cue two-hour-long argument.

After this exasperating experience, in which the other party felt they had confidently established that trilobytes were just adult woodlice who had gone extinct because they couldn't fit in the cracks of floorboards, I lost all hope and allowed them to get me very drunk and serve me barbeque.

Next time I'll skip to the booze and meat.

Their Confidence Was Informed By Experience
It is unfortunate that you probably ate the last dinosaur.

Eh?
I thought the earth was entirely covered in ice at least a couple of times during the last few billion years?

That's the subject of scientific debate
The mainstream consensus is that there was always at least a band of ice-free land and ocean around the equator. But there are serious scientists who believe that a "Snowball Earth" did occur, on one or more occasions.

Yes,
but the "snowball Earth" hypothesis refers to a period around half a billion to 650 million years ago, well before the evolution of complex life (or much life at all).

The Ice Ages, the last one of which ended only a few thousand years ago, were much, much less severe.

Humans frolicking with dinosaurs is still to come.
I read about it in Watchtower, so it must be true.
