The people who survive to form the next civilization will be smarter.

Guaranteed. They can't be dumber.

I thought that about some previous generations of politicians!

I know. We won't mention any names.

But people can survive above the Arctic (Antarctic) circle. Then the next ice age will drive them back south. I am beginning to think that evolution is driven by ice ages. We need them to make progress.

There's more than a slight chance that anthropogenic global warming could trigger a runaway scenario ending in global conditions that would last millions of years.
eg Release of all the methane in the Tundra.

Look at the Eocene conditions for comparison, lasting 23 million years.

Once planetary climatic conditions become extreme, there are no quick solutions even in geological timescales. Recovery from the KT impact was in the order of 4 to 9 million years.

At the opposite end of the spectrum, the two Snowball Earth scenarios both lasted 10 million years.

Those are real possibilities. But Snowball Earth was ended by volcanic eruptions. They can occur on any time scale. And then there are meteors.

They are all great incentives for rapid development of our technologies.
