If all of the nukes in the world went off at once, strategically spaced out to cause the most land coverage (I.E. some kind of Dr Strangelove situation), the world would look mostly the same. Green grass, blue oceans. It wouldn't be scorched earth. But, of course, those unlucky enough to live downwind, within 100 or so miles of a nuke, would get a healthy dose of radiation to their internal organs, as radioactive dust would be unavoidable. For decades, that fallout region would be uninhabitable, because radioactive isotopes would be incorporated into plants and animals. So yeah, not the end of the world, or even civilization, but I wouldn't want to live in that world.
