Once we get to sulfide injection we'll just factor it into acceptable levels of CO2 production, to keep things running until nothing can be done about adapting to climate change anymore.
If anything, Covid convinced me that's the kind of scenario to expect.
Of course I hope for something else but better be prepared for the worst.
Everyone is too concerned with their bottom dollar and it’s gonna be too late to change once the collapse starts.
While it sounds great on paper, the secondary order effects will last longer than primary and are very hard to quantify. It's clearly 10x-1000x cheaper to cut CO2 emissions now than to try to block out the sun with geoclimate engineering in a few decades.
EA's point that charities that provide malaria medication and vitamin A supplementation for pour children are very cost effective ways to save lives are very good. That might make other good points too. They are often very good at convincing people that certain charities are worthy of donation. I think it's possible that we'll see similar arguments form members of that group for extreme climate change measures.
As a general rule, EA groups have a tendency to latch onto ideas that are radical, ideas outside the overton window. You shouldn't assume that automatically means they're bad unless your heuristic is "we should never stray outside the overton window, ever".
I have no issue with radical ideas "outside the window" personally, but often find that EA groups tend to go right for barely workable "grand plans" and often don't listen to the people with boots on the ground, actually doing the work.
I'd give specific examples, but it would be doxing myself as many of them are extremely specific.
Yep, scientists already suggest it would disrupt rainfall in the 3rd world. Ironically the same nations that will be the worst hit from global warming regardless. What will India's reaction be when their monsoon rains fail because of the unilateral actions of another country? It's not a good idea to destabilize a nuclear armed nation.
