solar radiation management

“One of the things that we do know as pretty likely is that it's possible you could do solar radiation management that would deliver substantial reduction in warming for a very, very, very low cost relative to all the other approaches that we're seeing out ther…”

“If you compare it to, like, the cost of carbon removal, for example, on just a dollar per degree Celsius metric, it's, like, orders and orders of magnitude cheaper.”

“The rough estimates, just to an order of magnitude, are that, at least what I've seen, it might cost a couple billion dollars to deliver something like a half a degree of cooling, half a degree centigrade of cooling.”

“You could stand up and do a reasonably large scale test on your own without a ton of money, arguably without being detected doing so by the world.”
