I'm personally optimistic given what we're seeing happening in China in terms of energy transition. China has lots of scientists who must understand what's happening with the climate, and what to expect. I don't get the impression that there is nihilism in China like there is in the west, so they must think that this problem will be tractable.
I do expect that we will see a lot of global disasters happening as a result of climate change, and life will get hard around the world as a result. But I also hope that enough of humanity will be able to come together to push through these problems and ensure that our civilization continues.
I don't think there's any value in having a fatalistic view on this. We can't know that we'll make it, but all we can do is work towards making the world better and hope that what we do will be enough.
