If Russia or the US launch nuclear weapons, over 90% of the world population will die over the following 10 years. However, global warming would be solved.
Even using the most conservative numbers here, an all-out exchange between the US and Russia would produce a nuclear winter that would at most resemble the one that Robock and Toon predict for a regional nuclear conflict, although it would likely end much sooner given empirical data about stratospheric soot lifetimes. Some of the errors are long-running, most notably assumptions about the amount of soot that will persist in the atmosphere, while others seem to have crept in more recently, contributing to a strange stability of their soot estimates in the face of cuts to the nuclear arsenal. All of this suggests that their work is driven more by an anti-nuclear agenda than the highest standards of science. While a large nuclear war would undoubtedly have some climatic impact, all available data suggests it would be dwarfed by the direct (and very bad) impacts of the nuclear war itself.
You’re right. It won’t be 90% of the world population, but it would definitely be more than 90% of the countries involved (e.g. NATO, Russia, and China). As far as the world population, people in countries of the southern hemisphere might have more chances at surviving, but with geopolitics changed that drastically with an impossible to resolved food shortage, things could become chaotic pretty quickly. Don’t argue with me. Here are the sources I based my opinion on.

90% of people being dead and the other 10% being pre-industrial is what’ll fix global warming, we don’t need nuclear winter for that.
The direct effects on the world of a nuclear war between the US and Russia isn’t going to include killing 90% of the world’s population.
