It certainly is possible because we have the technology to do so. We are adaptable because of our tech and our communication. Plus the sheer numbers of our species can probably survive most things in some sort of way. Gigantic hurricanes aren’t going to kill someone in a bunker. Either is radiation or acid rain.

It is possible that we lose it all and have a runaway greenhouse gas problem like Venus. So I hear what you are saying. It can take us all out too. But it depends on what takes us out that keeps some of us here.
