vapor

Higher temperatures enhance the atmosphere’s capacity to hold water vapor, increasing the quantities of moisture evaporating off the landscape.

Additionally, the increase in CO2 allows more vapor to form in the air.

Perhaps most notably, it has a very low mass — 10% the mass of Jupiter despite being 80% its volume, with an atmosphere of water vapor, methane, carbon dioxide, carbon monoxide and ammonia.

Authorities ordered the evacuation of approximately 150 homes in a Ventura neighborhood Sunday because of “potentially dangerous levels of hydrocarbon vapors” and placed another 2,600 homes under a warning to possibly leave.

Water vapor is the only emission generated from the propulsion system.
