One result of increased global temperatures would likely be more water vapor in the atmosphere. Why is this?

    Warmer air will hold more water vapor.  There is more evaporation with warmer temperatures.  That said, predictions of increased water vapor resulting from our CO2 appears to be exaggerated.    Increased water vapor should result in more clouds and possibly more rain.  It should also lower the temperature difference between the cold and high temperatures.   It should moderate the temperature.  We have had mild warming for over two hundred years and the last hundred years isn't that different from the hundred years before it.   It isn't easy to determine what effect our CO2 has had on temperature and on water vapor.

      And saying "Increased water vapor should result in more clouds..." is unsupported speculation on your part. Can you show that? For example, large areas of the globe are covered by stratocumulus clouds, and as temperatures go up, those DECREASE.

    Increased CO2 makes more water vapor, a greenhouse gas which amplifies ... in the atmosphere — making any temperature changes larger than they would ... So if there is a 1°C change caused by CO2, the water vapor will cause the temperature ... insignificant global warming with increased atmospheric carbon dioxide.

    Warmer air means more evaporation. The evaporated water doesn't just disappear, it goes into the air/atmosphere.

    Warmer air can hold more water.  In fact, at -41C or so, the water vapour in the air freezes out as Ice Fog.  Warm air can hold a lot more liquid.

    As far as water vapour goes if the atmosphere warms it can hold more water vapour, the simplistic example of that is the water vapour content at the equator, this drops off steadily as you move towards either pole. But unlike jimbos unsupported fake statement, water vapour over the Arctic has been increasing for the last several decades.

    The Arctic is warming at almost twice the global average.

    LOL.  The OP is Dirac.  Why is Dirac now going anonymous?  Why won't Dirac honestly debate me?   

     

    Dirac said he has one account, but I noticed the # of Q&A in his profile has not changed for 3 weeks.  Dirac says ALL his content is open to everyone, but that is obviously not the case. 

     

    Dirac is a disgusting liar.

    The oceans will warm also this more water evaporates.

     The warmer the air the more moisture it can hold also
