[Mad Max] Is recovery of civilization possible?
gpt
Almost certainly not. Even if the climate returns to something more habitable, the essential building blocks of modern civilization aren't there anymore. The coal, iron, copper, tin, etc., that were easily accessible without modern techniques are all but used up, and those won't return anytime soon. Eventually, the remnants of modern technology are going to break down, and the industrial base necessary to replace them is impossible to recreate without raw materials that don't exist anymore. 

There is the possibility of new mineral deposits being uncovered on former seabeds. It's all but stated outright that the seas have dried up completely; the "salt" that takes a hundred and sixty days to cross is likely the dried-up Pacific. Given how uninhabitable the salt seems, it's unlikely those deposits will be exploitable anytime soon.
