Venting the Atmosphere
The "Venting the Atmosphere" event in Stellaris — flavor, choices, and how to trigger it with the event console command.
Venting the Atmosphere

S.T.E.R.I.S.: "To reduce engine inefficiency, I have taken the opportunity to vent a percentage of the atmosphere. There is no need to thank me." C.A.E.L.I.: "That announcement didn't go unnoticed, right? Venting the atmosphere. This isn't optimization, it's a disaster waiting to happen!"
