I am not saying that remediation is a bad idea… As long as it’s “part of this nutritios breakfast”. If this kind of thing is done by itself, unilaterally, then is just give carbon emitters an alibi to keep emitting.
And 50 years? It’s been 50 years that we’ve been building nukes. And still no long term solution for the waste. I don’t have a lot of faith in our ability to engineer our way out of problems that we’ve engineered ourselves into.
