Chris, your spot on that there is a climate emergency.
But the article I've linked suggests that it:s not gonna be a case of humans destroying the planet, or even causing their own extinction. It's worse than that!
Read the article if you get a few minutes. If not, just read the last couple of paragraph, which are here;
"This is why extinction isn’t the worst that can happen. It’s much more likely that climate chaos will intensify existing processes than bring about the end times. Instead of the final collapse, we should fear a world of unfathomable suffering. Of crop failures, of food shortages, of prisoners press-ganged into putting out fires, of those same prisoners dying in their cells from insufferable heat, of flooded cities, of billions of climate refugees, of gated private city-states, and eco-apartheid-preserving borders that ensure the survival of those in the worst affected regions hinges on securing super-exploited employment in protected enclaves.
"This might sound like science fiction. But as those suffering the catastrophic convergence of capital, colonialism and ecological crisis today will testify, it’s already happening. Rather than talking about “socialism or extinction”, “ruin or revolution” might better reflect our choice. After all, we can live in the ruins, though we’d surely prefer not to. Some of us, tragically, already do.'
