Water vapour is the #1 greenhouse gas and as the world warms so does the amount of water vapour in the atmosphere increase.
If all our motor vehicles were hydrogen burning then the greenhouse effect would be much worse than it is today because burning hydrogen produces water vapour.
It is true that the atmosphere can only hold so much water vapour before it precipitates - rains. But most of the time our atmosphere has nowhere near its maximum quantity so there is a lot of room for more water vapour in our atmosphere and, therefor, water vapour can violently increase global warming.
The amount of water vapour in the air would, in and of itself, increase the amount of viscious storms. The warmer the climate gets the more water vapour can be held and the cycle would seem to continue.
Right?
Should we continue to push for hydrogen engines?

It would make things worse for two reasons. One, Hydrogen powered vehicles merely move the source of pollution to power plants which than need to create a higher output to meet the demands for creating Hydrogen from water. Secondly, it will increase water vapor in the air thereby altering local climates significantly. It's just a political buzzword and idea for gaining support.
Fuel Cells are much better if and only if an efficient means of producing Hydrogen with limited pollutant output can be discovered. There is hope here as scientist found that sound waves do the trick, but they're still working out the energy input output data.

If we could convert from fossil fuel to hydrogen, I think that we probably would be better off. Fossil fuel produces water vapor also, but it also gives off lots of other pollutants. Hydrogen fuel would at least avoid that problem.
But it's a moot question, at least for now, for at least 3 reasons:
1) we don't have a good way to store hydrogen in a car's fuel tank in a quantity that would provide enough range even close to what a modern car has. It takes more volume to get enough BTUs to propel the car for 300 miles. The tank would have to be larger, or we'd have to have heavy, expensive, heavily-insulated high pressure storage bottles to keep enough onboard. Filling those would take half an hour or more, I'm told.
2) there's no infrastructure to produce or deliver enough hydrogen to the marketplace to replace even a few percent of the the market's current usage of gasoline or diesel fuel. So manufacturers will not build hydrogen-powered cars if they can't sell them because people can't get fuel for them.
In a catch-22, people won't buy cars that they can't get fuel for.
3) If someone did have a hydrogen-fueled car, it would be a nightmare if they got in a crash, and cracked the fuel tank. Remember the Hindenberg?
So for the time being (like the next 10-20 years), you'll probably see some sort of gas/electric or diesel/electric or maybe alcohol/electric hybrids as the most likely vehicles on the road.

even regardless of the truth that the humidity of the air in no longer one hundred% international each and every of the time, clouds nonetheless style and rain nonetheless falls, because community instabilities replace the flexibility of the air to carry water. The water cycles works VERY quick compared to the carbon cycle. Water vapor extra top the air receives bumped off back in some days. Carbon dioxide takes 1000's of 1000's of years to be bumped off. And it isn't trees that do it. that is many times existence contained in the sea that takes up the carbon, dies, falls to the bottom, and receives buried by technique of sediments and finally subducted deep into the interior of the planet by technique of plate tectonics. If humidity is going up, the quantity of rain is going up promptly. the quantity of CO2 bumped off received't pass up very nearly so straight away because those strategies are a lot slower.

water vapor forms clouds which reflect heat actually having the opposite effect and cooling the earth

Water vapor that enters the air via evaporation from the ocean is much much much much much much much greater than from auto's.

LOL are you saying that water is worst to the environment than gas? who do you work for?

Your analysis lacks scientific support and is overly simplistic. You need to do some more research.
