Wait, I’m confused, how many warheads get used in this TL, because unless it’s in the thousands there’s absolutely no way a nuclear winter would occur. The entire theory behind nuclear winter is very shaky to say the least, and considering how few warheads are on standby between Russia, China, Britain, France and America, I really doubt that it’d be very bad. I doubt even the casualties would get over WW2 levels if both sides only used the warheads that they have on standby.
 
Celebrity Subentry
After seeing the 1983 article on Black Sabbath I thought I'd search for any celebrities that were touring on the war date for this TL and I found out that Coolio was touring in Australia, thus meaning that he would have survived while being trapped in a country that would remain relatively stable in the aftermath.

This is how he looked on his Australian tour, when the war broke out it was already August 2nd in Australia so he had arrived in Sydney for the concert taking place later that day. When news of the nuclear war hit the Australian masses it was initially unknown if any missiles were on their way to the nation, so Coolio and the others working on the tour were sent to public shelters. While awaiting news on if missiles were heading to Australia Coolio and his associates were hearing news of several sources in the Northern Hemisphere going dead, and some people in the shelter were getting text message updates from friends or family up north and they all gave the same story of hundreds on incoming missiles until their messages also stopped. A few hours later Australian intelligence confirmed that no missiles were heading to Australian airspace so all shelters were cleared, but the atmosphere was ghastly. Coolio was in a state of shell shock due to the severity of the news and the scale of it made it hard to process. After he had enough time to truly appreciate the gravity of the situation he had a mental breakdown, police were sent to his hotel room and he was placed in a psychiatric ward for a few months.

Upon release he decided to redirect his emotions of losing everything he had back home to nuclear war into his rap music. In 2016 he released his first post-war single "Angels" to serve as an elegy to his hometown in Los Angeles with a strong anti-war message intertwined. It reached number 1 in the Australian charts and was his biggest hit since 1995's Gangsta's Paradise.
