Original Note:
Depending on the temperature and the amount of moisture in the air at the aircraft altitude, contrails evaporate quickly if the humidity is low, or persist and grow if the humidity is high. Since contrails are composed primarily of ice they do not pose health risks to humans. https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf
