The output is water, right? Wouldn't this put more water vapor in the atmosphere? Because water vapor also increases the greenhouse effect.

    Water doesn't linger in the atmosphere like CO2, and so much water evaporates from the oceans that anything we could do to put more water in the air is negligible. The only real way we can influence the humidity of the atmosphere is by changing the temperature with carbon.
