As I understand it the by product of producing hydrogen is water. I suppose millions of autos expelling water could cause a climate to become more humid. But, lots of people say we are running out of water. So, can't be all bad can it 🙄?

Hell, burning wood “creates” Carbon and Water - the water can be broken down into Hydrogen and Oxygen - the Hydrogen can be used as fuel and the Oxygen can be breathed by us - burn all the forests and we will have enough water/Hydrogen/Oxygen to meet all our needs......and enough Carbon to keep the graffiti artists happy too.....

Water vapor is a far more powerful “greenhouse gas” than carbon dioxide.

A water vapor tax will be necessary as the proceeds from carbon taxes dwindle.
