I think it's not quite so easy. There were many cities bombed in World War II (maybe 60 in Japan and additional ones in Germany), but there were only 5 or 6 firestorms. Similarly, the Kuwait oil fires created a lot of soot, but the plume is isolated to a given point, which causes it to disperse before reaching the stratosphere. The claim is that firestorms in particular would create climate change, because a single city-sized plume could carry the soot much higher than if the city burned and released the same amount of soot in an ordinary fire. https://en.wikipedia.org/wiki/Firestorm#City_firestorms https://en.wikipedia.org/wiki/Firestorm#City_firestorms https://en.wikipedia.org/wiki/Nuclear_winter https://en.wikipedia.org/wiki/Nuclear_winter
