This article is very vague. I get the feeling it doesn’t link to the underlying source research on purpose. This $3000 is the predicted cost over the remainder of the century, which means the present day value of the claimed impact is a lot lower. I also wonder if they accounted for the economic and social benefits of the flight to keep things balanced. And do they compound the benefits into the future as well, to perform an even accounting of 2100 costs versus benefits? I’m guessing not.
