The amount of water produced is insignificant comapred to the existing water vapor in the atmosphere.

You can do your own calculation with a water vapor concentration of soem grams per cubic meter on average earth and a troposphere height of 10 km

A good star is to comapre the CO2 produced with the existing CO2

Also consider that the water vapor rains down within a week

I do not think the water being produced in the way you have described is anything significant.

I think no one has analyzed the situation. If we look into the increasing trend in fossil fuel production and consumption, we are injecting a small river into the atmosphere every day.

The amount of water produced by burning fossil fuels is insignificant compared to the amount of free water that is already on Earth. The average depth of oceans are several km.

Different water sources have different role:

Glaciers

Ocean

Soil moisture

Atmospheric vapours

Plants body

Animal body

Ground water

Rivers

Water produced as a result of fuel burning may not be comparable with ocean, or may have no relation with ground water, but it may have role in atmospheric vapours, humidity, green house effect (GHE), soil moisture.

I gave you the

I gave you the quantitative numbers for the atmosphere and you apparently do not want to make the calculation yourself?

The amount of added water to the atmosphere is fully INSIGNIFICANT

Why do you repeat your question?

Dear Dr Nafees Mohammad,

Using the equation you quoted:

CH4 + 2O2 = 2H2O + CO2

it is clear that for every molecule of CO2 produced there are two molecules of H2O produced.

We know that CO2 in the atmosphere has increased from 280 ppm before the Industrial Revolution to 410 ppm today, an increase of 130 ppm. Therefore, using your equation, H2O will have increased by 260 ppm. Compared with the normal concentration of H2O in the atmosphere, which is around 3%, (30,000 ppm) that is an insignificant increase.

I might also add that the glaciers and ice sheets are melting which is adding far more water to the system than the combustion of fossil fuels.

In addition to the answer given above, the water abundance is subject to large variability in space and time, unlike that of the CO2, which is well mixed. This variability is orders of magnitude more than the contribution of excess water vapor to the atmosphere due to anthropogenic effects.

The point made by Nafees is important as some of the water released by burning fuels may stay in the air as humidity. There is an increased humidity in the air problem, I think, certainly in this part of the world and the source of this vapour or some of it could well be there.

Therefore, this question is very interesting. I applaud the author.

@ Michael

The amount of water is absolutely zilch compared to the existing water

I advice you to do the calcultaion yourself for a RH of 50% corresponding to several grams of water per m3 of air

Insignificant.

The earth is characterized by having 3/4 of its surface covered by water. Terrestrial water exists on the earth in the atmosphere as water vapor, in the oceans as liquid water ,as ice in glaciers and polar ice caps. It flows in rivers, streams and lakes and  under the surface of the earth as ground water. It is also found inside the earth bound up in rocks.  Water is a very mobile compound that can exist in three forms on the earth; solid (ice) , liquid (water), or or as a gas (water vapor).

The hydrological cycle is the movement of water through all of the places it exists on the earth in all of its possible forms  (cloud formation snow, hail, ice and rain and gaseous emission from volcanoes). No new water is produced by the hydrological cycle. It is the mechanism whereby the very mobile compound H2O moves and transitions from one phase to the other  and from one place to another on the earth.

New water is introduced to the earth and the hydrological cycle by incoming meteors, asteroids and comets (which are mostly dust and ice). Water content in these celestial bodies is introduced to the earth when they enter the atmosphere. A large number of celestial bodies enter the earths atmosphere Asteroid Fast Facts and the amount of water introduced from these sources is estimated to be significant but not enough to have produced all of the water on the earth. Did comets bring water to Earte

regards

Mostly, plants and animals use water as a raw material in their growth, but that water is eventually returned. Chemical reactions in the sea results in some trapped water in the bottom sediments again this water is returned eventually by volcanos. Some water is lost to space when UV light breaks up water in the high atmosphere, this is compensated for by the water we receive with meteors and comet dust.

The biggest movement of water on earth is between the sea and the land, this is the change from fresh water to sea water and back again, this is the most important cycle to the human race.

There is about the same amount of water on Earth now as there was in the Mesozoic period. All water that is breathed, drunk, and urinated by living things remains as part of the planet’s total water content.

The total amount is not exactly constant, as there are two fluxes of water between Earth and the rest of the solar system. There is a steady rain of water-bearing meteoroids hitting the planet, which slowly increases the amount of water. At the same time, molecules of water often dissociate in the upper atmosphere into hydrogen and oxygen due to ultraviolet light from the sun. Some of the hydrogen atoms have enough energy to escape from Earth’s gravitational field, and so are lost. This slowly decreases the amount of water.

In addition, tectonic plate subduction is constantly carrying water down into Earth’s mantle, and volcanoes are constantly spewing water out onto the surface again. The balance between these two processes can change considerably over time.

But all of these fluxes are small compared to the total amount of water on Earth, and two of them are in the opposite direction of the other two. So the overall change is insignificant, even when considered over long spans of geologic time.

Thank you Beemnet Mengesha Kassahun for your contribution. It was very helpful.

Interesting..

Sorry i see this is a little over a year old, but i was thinking about this tonight: What about the fossil water we are pumping from deep aquifers? Ice and deep aquifers are long term storage, i.e. that water has been out of circulation for a while, but now more of it is evaporating, condensing, draining into rivers, lakes, the ocean, etc. even shallow aquifers. In my estimation, this has to make up for some increase of atmoshpheric water that is cycling through faster. ideas?
