“IIRC in 2012 the Earth missed a giant CME by one week, and had it hit Earth there would have been 80% casualties in the US...”
By casualties do you mean injuries/deaths (to people)? Do you have a source? From what I could find, it would be really bad for infrastructure, but not something that would outright kill or injure most of the population.
Neat idea, and the step-by-step instructions are awesome. But wow, the scenes are mind-twisters. Especially the leopards. I think one briefly sprouted wings!
