If global warming is real, how can it be a threat when our species experienced far more drastic changes--and thrived--after the Ice Age?

Humans (and pre-humans) were almost wiped out. It was mostly luck that we exist today.

Because during the ice age there were no borders and people moved south to escape the worst of the weather.
There were a tiny number of humans compared to today and enough resources for everyone.
That is not what will happen when the 422 million people in South America move north and the 1.2 billion people in Africa do the same to escape starvation.

Ask a farmer about what they will be doing this year. Too much rain has ruined the planting season.

That is just too much of a logical question for some of the minds here. Global warming is real. If it wasn't we couldn't exist on this Earth. But what I presume you mean is Catastrophic Anthropogenic Global Warming (CAGW).
That definitely does not exist. There is no credible scientific evidence of it.
Yes, and man can adapt. Just look at the various conditions that man exists under historically and even today. We have an average temperature of 79 deg F in Algeria and 49 deg F in Siberia, for example. Men survive in both places and have for centuries.
So why are these saviors of the Earth going bonkers over a temperature change of less than a degree over a century? It boggles the mind. They must have a hidden agenda.

There might have been 4 million people alive during the last ice age - most of them far from the ice - now there are over 7 billion of us, many living on the edge. Things are gonna get pretty nasty - cuz people are pretty nasty - can't even understand what's going on! We're all Bozos on this bus but the republican party has gotta be the biggest mistake God ever made!

it is real. we did not have 7 billion people or coastal cities then.

Our species has existed for over 200 thousand years living in Africa until about 80 thousand years ago. Neanderthals, Denisovans, Red Deer Cave People, H. floresiensis, and maybe a couple others shared the planet with us and some lived in the colder places in Asia, particularly Neanderthals and Denisovans. When we left Africa, DNA evidence suggests humans hybridized with Neanderthals and Denisovans.
Our most recent period of glaciation ended just over 13 thousand years ago and it warmed to a climate optimum about 7 thousand years ago. Our species now survives in places like the Arctic to the Kalahari to the Amazon. We are quite adaptable due to our intelligence. I agree that some people grossly exaggerate the threat of warming. I think many of our ancestors would be pretty disgusted with the whining when they lived in very harsh conditions. We live in warm wonderful times and those that complain live in relative comfort. It is quite an easy time to survive.

There were only about one million humans when the Earth started warming after the last Ice Age, which took maybe 20,000 years for a 6 degree average temperature increase.
Now, we're looking at trying to keep 7 billion humans alive, with an anticipated temperature swing of 4 degrees, in only a few decades. We won't succeed. I don't think we'll go extinct - but billions will die.
