Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

At the very least, even basic electricity production requires copper windings. Which requires copper wire. Which requires refined copper. Which requires copper ore. Which requires copper mining.
Generations of people with manual tools will need to die in the mines for enough electricity to be generated to run a small medical clinic, let alone get post-climate humans to a point of modern civilization.
While it's definitely bleak, it's not quite as bleak as that. Remember that we're leaving behind vast amounts of 'waste', much of which contains things like copper, aluminium, steel and other useful components in relatively easily refinable states.
Future civilisations will be digging through our waste, wondering why we were so profligate, but glad to have it all to hand.
I had thought about this scenario before too, but now I can think of many other scenarios where this doesn't happen.
Examples: a complete loss of most of humanity's technological know-how to where we don't even know how or why use those materials, loss of knowledge of where many of these (mostly difficult to harvest?) resources are buried, and warring between factions for access to these resources. Not only each of those scenarios individually, but also a combination of all of them plus other factors working against this happening.
I think that the eventual best case scenario for humanity will be going back to pre-industrial living and technology.
Those are fair points, but consider that they just put the next civilization at the same level we were; we didn't have the technological know-how until we invented it, we didn't know how or why to use different ores until we worked it out, we didn't know where the ores were to be found until we gound them, and harvesting pre-refined material is much less intensive than that, and well, we've warred, and continued to war over access to resources.
Basically, we've dug up lots of the easily accessible ore, which has a low density (you need to dig up maybe 4 tonnes of rock to get a tonne of iron ore, and that is only between 50-75% iron, for instance) and buried it more shallowly, and at higher density. There's still work to do to extract it, but it's manageable with fairly low tech.
Energy sources are a little more complex, but we've bound up a lot of hydrocarbons in plastic and the like, which should be usable, if not ideal in their raw form.
Those are good points too, that I hadn't thought about. I thought it would be challenging, but maybe it wouldn't be as challenging as I had imagined it.
But who knows, maybe we would be better off going back to pre-industrial times anyway?
But how would I find interesting conversations on Lemmy if my highest tech gadget was a loom?!? :)
Haha, we would have to go back to the printed press and handwritten letters!
