Imagine thinking of bearing children into a less habitable world because of climate change, and its resulting ecological decline and social and economic strife.

I get what where you are coming from, I'd like to have children some day, but is it fair to have children in a clearly becoming bleak future? Never mind wars and economic recessions, because human society always recover from it. But climate change? It is a different beast than hunger or wars because it renders the entire planet inhospitable. Modern human society is not able to tackle or evolve from the rapid environmental changes caused by us.
