I can't see us throttling the fossil fuel companies, and I'm not at all hopeful of any carbon drawdown technology more complex than trees will happen, and I don't think we can plant anywhere near enough trees in places they can grow, and replant those that are burnt down

I think Kim Stanley Robinson has it right in his sci fi that all the coastal cities are screwed in a hundred years or so and presuming we don't fuck the biosphere in general enough to wipe out civilisation we'll be dredging sand just offshore from the old beaches to build new ones

I don't live in the UK or Europe but I wonder if the land rise (the rebound from the last glaciation) can keep up with sea level for long. The 10m rise from the west Antarctic ice sheet failing would have certainly outrun it, being described as like a tide that keeps coming in (look up 10m in a flood map to see how bad that would be for an overnight change!) but that's off the table. The Antarctic isn't melting like the Arctic. At least not yet.

I almost hope for life extension so I can see the disaster, but it'll suck.

It's possible, just not probable because the people actually running the world don't give a fuck about the rest of us.
