Even the worst case scenario isn't really apocalypse, it's just constant precarity, more frequent droughts and famines, and resource extraction jobs becoming more dangerous (as regions of the earth do become uninhabitable for humans). So, lucky for you you're not focusing on the wrong thing by freaking out about the escalation of fascism. The disaster that climate change brings very much puts us in a socialism or barbarism scenario where the escalation of fascism is at the centre. I kind of hate it because we live under soft-fascism in the era of plenty, worsened and made explicit by the refugee crisis in recent years, I just don't see how the left at its current state can fix this. But maybe we'll get the reins of power as millennials and zoomers get older.
