Your article is a rewarding read. I appreciate the time and thoughtful effort you put forth to write this.
The basic takeaway I get from your article and others that point to the unknowable complexity of our climate emergency (political, economic, cause and effect of natural laws, and so on) is that our civilizational survival is dependent on nature acting to neutralize our harm to the biosphere in (unknowable) ways that will allow our species to slip through the coming bottleneck.
Maybe some parts of the unfolding dynamic of the climate disaster (from the human perspective) will be ameliorated by human action. But whatever actions we take will be live experiments and flaying about in a darkness of knowledge concerning the true complexities of the biosphere that gives us life.
