To a very low extent she’s somewhat correct. I’ll preface by say mtg is an idiot

Cloud seeding is a thing where an aircrafct drops something into clouds and it somewhat adjusts the type of precipitation. And nasa has a machine that simulates extremely loud rockets and it shoots out a mix of hydrogen and oxygen “h2o?” and it creates a cloud that will actually rain. However this is only done in one place i know of and is somewhere in the middle of nowhere Mississippi.

To what extent does mtg think weather can be controlled or created is the question and i imagine she’s implying we can steer a hurricane or send tornados to our enemies
