A brief review of the online resources from around the world such as this: http://globalskywatch.com/stories/my-chemtrail-story/chemtrail-information/chemtrail-types.html#.W6e79flRdaQ

All agree that much of the "chemtrails" being sprayed have metallic components. The altitudes at which they're being sprayed form an "umbrella" of metallic compounds, water vapor and other components.
Metals and water are conductors. As the "umbrella" being spread above our heads is at a lower altitude than any projected EMP weapon would be detonated, or a CME event impacting us, could it be that we are being protected from a greater harm than minor health effects among a few individuals?
