- Thorrez 4y agoMy point is that driving an engine that emits just water vapor for 1 day won't have a permanent effect on the atmosphere, because the water vapor it emits will eventually rain down, and the level of water vapor in the atmosphere will go back to what it was before driving the water-vapor-emitting engine. On the other hand, driving an engine that emits just CO2 for 1 day will have a permanent effect on the atmosphere because the CO2 will stay there.

- Thorrez 4y agoCarbon dioxide I think. But I think it's a fairly balanced process of trees eating CO2 and trees dying and releasing CO2 back. I don't think this action changes the amount of CO2 much since it evens out. Humans in the last 200 years have massively increased the amount of CO2 in the atmosphere by finding carbon buried deep underground and releasing it as CO2 into the air. https://www.co2levels.org/ https://www.co2levels.org/
