I didn’t say there was no need to be alarmed, I said civilization isn’t going to collapse.

These also aren’t the same things. Cloning is a technology that will likely continue to be more and more possible. It’s not really a question of if, but when. Even then it was just a creative suggestion.

Modeling civilizations responses to climate change is basically science fiction. Yes, bad stuff will happen. No, you can’t predict that society will collapse because of it.
