The chemtrail conspiracy theory posits that some trails left by aircraft are chemical or biological agents deliberately sprayed at high altitudes for purposes undisclosed to the general public in clandestine programs directed by various government officials. This theory is not accepted by the scientific community, which states that they are just normal contrails, as there is no scientific evidence supporting the chemtrail theory. NOAA publishes a list of silver iodide projects and the companies that perform the atmospheric releases. Reporting weather modification is required by US Federal law. There is no scientific evidence silver iodide leads to chemtrails in the sense that fire would produce smoke but it is the only reported weather modification of significance.
