Frankly this kind of doomsaying view has no basis in reality. While it's true that unmitigated global warming will impose a very large economic cost, it's simply not the case that it's going to turn the world into some unlivable hell-scape. There's just no basis for that belief in the actual evidence.
The best estimates say that global warming will lower per capita GDP by somewhere between 5-20% by 2100. That's a tragedy, because in aggregate it represents a huge amount of unnecessarily lost wealth. But a 5-20% in GDP per capita does not mean that we'll be dying in the streets.
Let's be very conservative and assume global GDP per capita grows at 2% per year. In the baseline scenario, the median world citizen would still be 390% richer than the average person today. Applying the worst global warming impact (20% of GDP), the median person would still be 290% richer than the average person today.
Unmitigated global warming will make the people of the future substantially poorer. But not nearly by enough to cancel out the effect of continuous economic growth and technological development. It's almost certainly the case that the people of 2100 will enjoy higher living standards than the present.
