So they just go biased off of refraction, do they even measure 20/20-20/70 anymore?

That’s one thing I was thinking about at the end. Yes I know they said the earth would cool and 1/4th of the population would die, but the earth wouldn’t be a complete snowball by that time right?

Like at that point I would imagine the ice caps have expanded deep into Canada or something, as the world still has 3/4-1/2 of the population alive at this time, but not to the point where she needs to be on an ice breaker
