NASA Admits in one of their videos "To observe how winds move high in Earth's atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around" Read it for yourself http://www.youtube.com/watch?v=CKLEIr5y7sg
Meaning Chemtrails exist, and people who claim otherwise are ignoring poison in our skies.

Barium reacts with almost all the non-metals, forming often poisoning compounds.

Small amounts of water-soluble barium may cause a person to experience breathing difficulties, increased blood pressures, heart rhythm changes, stomach irritation, muscle weakness, changes in nerve reflexes, swelling of brains and liver, kidney and heart damage.
