You underestimate the threat of eco-fascism. By that I don't mean green party politicians, no, I mean literal facists who blame climate change on overpopulation and who believe that the population has to be cut drastically. In the most basic form this would mean closing our borders and making sure nobody can cross illegally by using lethal force, if necessary.
Climate change is a result of overpopulation and overconsumption, though. It's right there in the name. The climate is changing as a result of anthropogenic activity. I fail to see how eco-fascism affects the outcome here, if we do not cut our population and consumption the planet will do it for us.
I'm not certain I do. I feel like we may be arguing the same side here? What I'm hinting at is that unless concrete results don't begin to materialize and that right soon the resulting climate driven geopolitical upheaval, and knock-on effects to global logistics, is quite likely to result in a significant downsizing of both global GDP and the world population. Perversely both of these obviously bad outcomes will very likely improve global carbon emissions. Here's a really shitty joke for you: How do you reduce your carbon footprint by 100% overnight? Shoot yourself in the head. How do you reduce your carbon footprint by 900% overnight? Go shoot your neighbors in the head. :/
