Fusion would solve a lot, but even if we invent room-temperature superconductors today, it would still take so much time to roll fusion out on a big scale and replace oil infrastructure with electric infrastructure.
I tend to be very pessimistic about climate change, but I hope I’m wrong.
I was more stating what I think will happen rather than wat we should be doing.
In terms of pure physics it is ofc easier to turn off the metaphorical tap, but in terms of power and politics we seem unable to transition to renewables. And I’m afraid once we switch on the geo-engineering button we still won’t transition. Only once oil is priced out of the market completely, be it fusion or abundant solar and wind (with energy storage), will we make the transition. But again I might be too pessimistic.
