Everything is fine, the earth simply won't be habitable for humans. The Earth will spin on without us when we inevitably allow industry to destroy humanity by making earth uninhabitable by human life.
It's what we deserve for being so stupid as to see this happening and doing nothing about it to stop it or slow it down. There's plenty of climate change advocates which are almost always drowned out by the chorus of companies and climate deniers who believe propaganda over science.
What people deserve, and what's going to happen to them are not mutually inclusive.
I'm also going to state that IMO, it's not just a few corrupt men. There's lots of them.... Lots and lots of them.... Not the majority by any stretch of the imagination, but certainly more than a few
It won't matter if a small area is still habitable. The resolution of 7 billion people trying to fit into a space that fits a fraction of the population will end the species.
It took less than 1% of the population of Europe moving around to nearly break the EU. Watch what happens when it's 10 to 20% of everyone everywhere.
The movement of a tiny group of people relative to the size of the EU drastically shifted the entire political structure of the EU, leading to Brexit and several other countries considering the same. Magnify that affect by the number of people that will be moving due to climate change, and you get an extinction event.
Will end the current age of civilization? Most definitely.
Will it end organized societies as we know them? Probably?
Will the human beings go extinct? Probably not. Its not crazy to think that we'd face a bottleneck of only a few hundred million humans or less. But there are people all across the economic and geographic spectrum who are prepping. The rich will survive at their polar fortresses. The poorer will survive underground, or at high altitudes.
You make it sound like humans are the only ones affected by climate change. Sea turtles, elephants, polar bears, pandas, there's a fuck load of animals we're directly killing off. Everything is most certainly not fine, even if you don't give a single shit about innocent human lives.
I remember when I passed my test the mid 00's if I did a long motorway journey my bumper and windscreen would be an insect graveyard.. now it's next to nothing.
We will take a large chunk of the planets life with us. I don't think we can destroy it all however, the planet will get to intelligent life eventually.
