I’m too tired to respond in detail but this underestimates the scale of the problem. There is no “adapting” to the scenario if we don’t stop kicking out CO2. We’re talking billions dead and most large species extinct, over the course of decades at most, depending on how quickly the planet flips from one steady state to the next.
Sea level rise would be no problem. Storms would be no problem. But it's hard to imagine how we could possibly adapt to the worst case scenario, which would be if runaway feedbacks triggered conditions similar to early mass extinctions...
This old article from ScientificAmerican still keeps me up at night.
It scares the life out of me that even on HN, a community of generally scientifically-engaged people, the scale of the problem is often not understood.
We are literally looking at the end of civilisation as currently constituted, and billions dead, and we are not doing anything close to enough.
