As he states, cold periods and ice ages are few and far between in geological time.

Billions of years ago, Earth was just a hot mess. No oxygen, no oceans, just endless eruptions burping out toxic gases. Volcanoes were like the planet’s first chefs, mixing up a nasty atmospheric stew of CO2, nitrogen, and steam. Tasted like shyte, smelled like it too but it got the job done.Then some microscopic overachievers aka cyanobacteria showed up and went, Thanks for the CO₂, we’ll turn this shyte into oxygen. Fast-forward a few billion years, the oxygen thieves of today, happily breathing in volcanic leftovers

How long has there been ice on the poles?

But the South Pole hasn't always been frozen. So when was the last time Antarctica was ice-free?

This ice cap formed relatively recently in geological terms, experts told Live Science. "I think most people would say 34 million years ago was when the ice sheet first formed in Antarctica," said Eric Wolff, a paleoclimatologist at the University of Cambridge. "[Previously] most of it would have been like northern Canada today — tundra and coniferous forest."

Global temperatures are a key factor influencing the extent of ice coverage. Around 50 million years ago, the world was about 25 degrees Fahrenheit (14 degrees Celsius) warmer than it is today, but temperatures steadily decreased over the following 16 million years. By 34 million years ago — a time period known as the Eocene-Oligocene boundary — the climate was 14.4 F (8 C) warmer than it is today.

When was the last time Antarctica was ice-free?

Antarctica is covered by a miles-thick ice sheet, but was that always the case? And when was the coldest continent ice-free?

Yes, 34 million years ago is a long time ago for Civilizations to be living on Antarctica.

I'm... not??? (have you confused me with someone else???)

I'm just pointing out that 34 million years is waaaaay before humans were around.

Maybe, sorry.

Yeah, we've only been around for like 150 000 years or something where we just magically appeared one day.
