It started off as two horizontal aerosol trails left behind by special geo engineering aircraft. I watched those trails expand, and the wind dispersing them slowly but swiftly. Within 15 minutes, I saw clouds form out of these chemical trails. I will now refer to them as chem clouds.
This chem cloud is then heading east, growing as it picks up more aerosol mass, and its edges becoming more linear. It wont affect us since it will end up east of calgary, but next time you see a straight-edged cloud coming from the west, re-think: is this a chem cloud that has picked up moisture, or one that was intended by nature without designated aerosol-spraying aircraft?
