Based on real info, but not solely. We had to run around cleaning up last time we meddled with the weather. Nah. Joking. It is well-known that weather is not merely local. Mess it up one place and you might trigger climate change. But you might also not do it. It depends a lot on where you mess it up and how. Disrupt one of the major ocean currents and you're sure to get climate change somewhere. We've not studied it sufficiently to say whether a single thunderstorm is enough, but there are enormous forces at play in one, so it is possible. But again it depends on the where.

How much of a lesser change might occur if you didn't just create a storm, you just manipulated what was already around you into the area/region's type of storm? Like going to the Easter section of 'Murica, and then using the conditions that are already there to form a tornado?
