Chemtrails are the trails that are left behind by some airplanes. They're usually silver iodide (AgI), potassium iodide (KI), or Dry Ice ( CO2 (s) , Solid Carbon Dioxide). They are part of a cloud seeding program to make it rain or snow more to help prevent droughts, and to try to cool earth a little more by creating more clouds. It's good for water, but insufficient for global warming, and greener energy options to reduce CO2 emissions (like solar, wind, and maybe nuclear energy) are needed and not dumping your trash in the ocean so that turtles can eat the jellyfish and not sting you during the summer. There are more wildfires now. Will the earth cool down in time?
Tyler: I'm sweating! Stupid summer!
Cloud seeder plane: *flies by and creates more clouds, leaving chemtrails, clouds turning grey and raining.
That nagging cough you get that never gets too bad but also never goes away despite being perfectly healthy otherwise, taking tons of vitamins and trying all your natural home-remedies. A direct result of breathing chemicals (barium and aluminum) sprayed into the atmosphere by the government.
"Dang, I've beendrinking tons of tea and using my neti pot but I still can't shake this chemtrail cough, must be from that grid they sprayed last week."
Contrail-like cloud left by aircraft believed by "spiritual" people to contain chemicals or crystals. These chemtrails are allegedly part of a secret government program either to save earth from global warming or to kill off half of humanity.
Spiritual guy: Look! That's a chemtrail. I wonder what the government is doing to us.
