We have there options:

1. Continue fossils and make earth uninhabitable for a medium (on the scale of humanity) duration of time.

2. Switch to renevables, even if it means changing our way of living, maybe overproducing less, having less ultra riches etc.

3. Switch to nuclear, which isn't fast enough to stop the fossil problem but also contaminates earth for a ultra long amount of time and also is way harder to get rid of (we have at least in theory options to get co2 out of the atmosphere even if its not at all practical/usable e ough to help us with our current situation, for nuclear waste there is literally nothing you can to except wait.)

No sane person I met ever argued for 1, but since some time Americans seem to start arguing for 3 instead of 2 with literally no good arguments.
