I mean, it does, but only for a very little while. After a few decades, the cooling effect of a nuclear winter would be gone, while global warming will only cool down naturally over thousands of years. Either way, humans would be fucked, since nuclear winter cools the Earth by up to 8 degrees - that’s an ice age. So nuclear winter would actually make things a lot worse for humanity (even ignoring radiation and destruction), since the few survivors of the global ice age would have to face global warming next.
