It's an interesting thought. Mass displacement will be a huge issue though. While we do have plenty of landmass in theory, migration of major cities is just.. I cannot possibly fathom how that could ever be organized. We'd panic, loot grocery stores, rob pharmacies, etc. I mean look at what this pandemic has done. You can't even buy cans of beans or toilet paper! My local store is out of bags of dry rice. Of _rice_. I don't recall where I heard it but before I knew it was a quote, I used to say this all the time: humanity is three square meals away from total annihilation. One day without food and humans will revert right back to our caveman "attack other human, take food" lizard brains. I definitely went a little off topic from your original post but, "adapt to the changes" isn't honestly something I can fathom happening. I don't know where you live - be it a city or suburbs or otherwise - but think about 30 million people showing up and tell me that doesn't end in a massive disaster.

Massive disaster can be a huge distance from human extinction. A 1% die off is a massive disaster but even a 99% megadeath is 75 million people short of killing us all. I haven't seen any likely AGW scenarios that get us close to that. Maybe someone could point me that way.

  I was using the Planet Venus as a historical precedent of what happens to a planet in our solar system in the conditions of a runaway greenhouse gas effect when I wrote that. I'm a cryptography-focused security engineer, not a climate scientist.

    Here's a credible paper asserting that the net feedback is negative: https://www.tandfonline.com/doi/full/10.1080/16000870.2019.1699387 https://www.tandfonline.com/doi/full/10.1080/16000870.2019.1... I'd have to know a lot more before deciding that either a runaway greenhouse or net cooling is plausible, let alone likely.
