Being "stuck" has made the rise of civilization possible. Otherwise it would not have happened. What is your cause for concern. that being "stuck" might not last? If so, I agree, a new ice age would be a death sentence for billions of people.

A couple of points. The closer you move to the equator the more area to circumference Earth. Meaning there's more area for global population to move into than is present between northern and southern latitudes.
The much greater point is that technology advance is exponential. It starts out imperceptibly slow but as time passes the technology advances occur super rapidly. Presently man's technology advances are at an explosive point on the curve.
Using the year 2000 as a benchmark, the technology advances made in 2000 were 200 time that of advances made in 1900. Whereas the advances made in 2100 will be 20,000 times what they were in 2000.
Long before the next Ice Age man will have solved the problem of going extinct due to climate change.
Like wise, long before the Sun burns out man will have solved the problem of where to live.
[As an aside. In 1800 technology moved very slow -- almost imperceptibly slow. The founding fathers lived twenty years and experienced very few technology advances. Presently, technology advances change the way people do things several times a year.
