There is not less water vapour in the atmosphere. In fact, as the earth warms, the warm air is able to hold more water vapour. Water vapour is a greenhouse gas, so the air gets warmer. So it can hold more water vapour. And so on.
This is one of what is called the "positive feedbacks" of global warming!

∙ 14y agotwo reasons,
1. burnoff. water vapour exiting the earths atmosphere due th comeary impacts, and solar flares. this cotributes to a very small loss.
2. cooling temeratures. lots of the water present long ago is now locked in icecaps and the oceans due to temperatures being cooler than they were 4500 million years ago.

∙ 14y agoAs the Earth is getting gradually hotter because of global warming: the warmer it is, the more water from lakes, seas and oceans gets evaporated and the more water vapor there is in our atmosphere.

What is water vapor is?
Water vapor is simply water in the form of a gas. Liquid water turns into water vapor through a process called evaporation.
What is meant by the phrase The air is saturated?
It means that the air is holding as much water vapor as it can at that temperature. Any increase in moisture or decrease in temperature at that point will result in water condensing.
What causes changes in the amount of water vapor in the atmosphere?
Temperature, pressure, and water availability. For example, if you decrease temperature, the air cannot hold as much water vapor, this is the main cause of dew in the morning. If you add a large supply of water, like a lake, into a desert region the air can act like a sponge.
What does water vapor become when it evaporates?
when water evaporates it condenses and becomes water vapor:)
Water vapor is water in the form of a?
Water vapor is water in the form of a gas.
What air ability can hold water vapor?
decrease in the temperatue
How water turns into vapor at normal temp?
A large DECREASE in the surface pressure will result in water turning to water vapor at room temperature.
Does cutting down trees decrease the amount of water vapor in the air?
no
Will water vapour decrease in amount after being exhaled by a human and before it was inhaled by a human?
exhaled water vapor will be greater than inhaled water vapor
If salinity decreased at the poles the water near the poles would?
decrease in density and become water vapor
What effect does increase water vapor have on atmospheric pressure?
it causes a decrease in atmosperic pressure A+
Dissolving an electrolyte in water results in the formation of?
a decrease in the vapor pressure of the liquid
How does melting point change as the water content of rocks increases?
The presence of the water in its vapor phase causes the melting point to decrease and the rock to melt and absorb the vapor.
When water from the ocean evaporates and turns into water vapor the amount of water decreases or increase?
The amount of water in the ocean temporary decrease.
When evaporation turns into condensation is there a increase or decrease in energy?
There is never an increase or decrease in energy, energy cannot be lost or gained. On the other hand, gas is at a higher level of energy than liquid. In other words, water, when condensed from water vapor, is lower in energy than the vapor it was condensed from.
Why does dew form?
temperature goes down at night and as temperature decrease the air can hold less water vapor/moisture
What happens to relative humidity if the amount of water vapor in the air stays the same and temp increases?
The relative humidity will decrease.
