"Emitting only water vapor"--which is a much worse greenhouse gas than CO2.
- XorNot 2y agoYou might want to consider that 70% of the planet is covered with water which emits a lot of water vapor per day, everyday. Water vapour condenses out of the atmosphere in a matter of minutes to hours. CO2 in the atmosphere has a half-life of 120 years.

- tzs 2y agoYes and no. Yes, water vapor is more effective at warming than CO2, and is responsible for over half of Earth's total greenhouse effect. But humans have very little effect on the amount of water vapor in the atmosphere [1]. Emit a ton of CO2 and that CO2 remains in the atmosphere for hundreds of years. Emit a ton of water vapor and it is gone from the atmosphere in weeks. The average emitted water vapor molecule only stays for two weeks. So no, as far as emissions go emitting CO2 is much worse than emitting water vapor.

- Terr_ 2y agoDon't worry, any excess water vapor quickly falls out of the atmosphere. Literally. As rain.
