True...but an article full of FUDdy phrases - vs., say, measuring actual negative effects (enhanced greenhouse warming, damage to the ozone layer, etc.) from the actual exhaust plume of an actual SpaceX rocket - causes me to suspect that there is no substantial problem here.
The original article is prominently linked above and below the linked article, which is why I saw no need to provide an extra link and pointed to the fluff summary article instead.
