Climate: role of water of human / hydrocarbons?

[Christophe]

I have not found the subject of anthropogenic water vapor emissions and particularly water of hydrocarbon origin (gas and oil) ... if anyone remembers?

"They say" that this water is negligible compared to the evaporation capacity of the oceans, it is true. Only here ... if it is true instantly (over a day for example), it is really in the long term given all the water that we have "created" from all sides and injected into the "cycle of 'natural water' for decades?

Here is 2 topic that talk about the problem of water vapor of nuclear origin:

But this water vapor recondenses.

In the end, the water that comes from the combustion of hydrocarbons is ultimately only a fraction of the annual increase in the height of the oceans.

Yes, that's what we think a priori, but this supply of fresh water in the "oceanic system" (we create water from atmospheric O2 ... to naturally reverse this reaction there is no than thermolysis) ... can it not contribute to upset it?

[highfly-addict]

... to naturally reverse this reaction there is only thermolysis ...

And photosynthesis?

[Christophe]

I did not know that photosynthesis cracked the water ???

[highfly-addict]

Well if ! Counterintuitive can be but still true!

For those who still doubt: http://fr.wikipedia.org/wiki/Photosynth%C3%A8se#Le_photosyst.C3.A8me_II, step 6.

Indeed ... again a big thank you to the national education who did not know how to teach this to a bac + 5 ...

Mama mia!

Some have forgotten that forests produce oxygen?

[chatelot16]

given the enormous amount of water on earth that evaporates and condenses as it wants depending on the temperature, the production of water by combustion of hydrocarbons is unimportant

It's my point of view.

What comes out of the fuel deposits: oil + gas + coal.
By combustion turns into H2O which does not return to the deposits but becomes surplus.
So it's over-plus. who accumulates, accumulates, accumulates, accumulates ...

Edit: it's the opposite:
, promising accumulates, accumulates, accumulates, accumulates, accumulates...
