We should all stop showering, so that we stop adding more water vapour into the atmosphere. All involved climate scientists and climate politicians should stop showering, and recommend everyone else to do the same, to show how serious they are about this.
All fountains, water parks, and perhaps even all fire departments should be closed as well, to prove how dedicated they are to this.
Water rationing is a given, as excess water consumed can be converted into vapour and added to the atmosphere through breathing and sweating.
The planet is at stake here!
