When adding the reduction agent ammonia formed by e.g. decomposition of urea, nitrogen oxides are converted into harmless nitrogen and water vapor over the catalytic converter.

Such physical changes to the atmosphere might last only hours or days, he notes, but any subtle chemical changes — including those resulting from the extra hydrogen added to the air when ultraviolet light breaks down the water vapor — would persist much longer.

The upward trajectory of the air gives shape to the towering cumulonimbus clouds, and if the air is heavily laden with water vapor, it adds mass to the clouds, as well.

«The product is first frozen, then the sublimation process converts the ice into water vapor, removing most of the moisture from the product while keeping the nutritional value virtually the same,» Milchman says, adding that this is a fairly recent innovation in food preservation, one that offers several benefits over other methods, such as using artificial preservatives or dehydration, which can affect the appearance and composition of products.

When heat is added to water, water becomes vapor.

I ask this because, theoretically, given a relatively closed system, with heat energy being added, thermal expansion and contraction of gas and water vapor, more wind speed, more shouldn't this also mean more extreme weather?

So the rising trend in the lower curve is going to represent much more water vapor added to the atmosphere than the declining top curve represents as leaving it.

The troposphere is currently cooling radiatively at about 2K / day, and adding CO2 to the atmosphere generally increases the radiative cooling (primarily through increases in water vapor, though how these details play out also depend on the details of the surface budget).

It also seems that even though the selective absorption of specific energy bands by different molecules IS the mechanism to add energy to the air, the energy absorbed by CO2 & especially Water Vapor is extremely rapidly dispersed by molecular collisions to ALL the components of the atmosphere, so that the N2 and O2 also heatup, and all the atmospheric components assume a uniform temperature (ie global warming).

Words only have meaning in context and while it may be true that water vapor is a greenhouse gas in the sense that more of it in the atmosphere will absorb more infrared radiation and warm the climate, it is not a greenhouse gas in the sense that it is a gas we need to seriously worry about adding directly to the atmosphere.

(PS regarding Venus — as I have understood it, a runaway water vapor feedback would have occured when solar heating increasing to become greater than a limiting OLR value (Simpson - Kombayashi - Ingersoll limit — see http://chriscolose.wordpress.com/2010/08/23/climate-feedbacks-part-1/ — although I should add that at more «moderate» temperatures (warmer than today), stratospheric H2O increases to a point where H escape to space becomes a significant H2O sink — if that stage worked fast enough relative to solar brightening, a runaway H2O case could be prevented, and it would be a dry (er) heat.

But then there's feedbacks within the stratosphere (water vapor), which would increase the stratospheric heating by upward radiation from below, as well as add some feedback to the downward flux at TRPP that the upward flux at TRPP would have to respond to via warming below TRPP.

Now adding back the CO2 will have a larger magnitude of forcing than the initial removal because there is much less water vapor, and the water vapor feedback in terms of W / m2 will be smaller in magnitude because of the overlap with CO2.

BUT that if we continue to add CO2 to the air, the air has the added heat capacity to get warmer, IF and ONLY IF driven by the sun, but rapidly come to equilibrium with the ocean, by means of rain and the daily heating & condensation of the water vapor feedback mechanism.

But in the end, all of the water vapor adds somewhat less than 1.8 C to the original 1.2 C for a CO2 doubling in the fast feedbacks.

Rather than break up low level clouds, skeptics see the water vapor adding to the low, thick clouds (such as stratocumulus) which primarily reflect incoming solar radiation back into space.

Second, that in calculating climate sensitivity, the GHE due to water vapor should be added to that of CO2 as a positive feed back effect.

CO2 is absorbing other wavelength than water vapor, so the effects do add up I imagine.

The added carbon dioxide will of course keep absorbing in the IR but it can not cause the greenhouse effect that IPCC calculates for it because the reduction of water vapor I referred to cancels it out.

Add CO2 — > increased atmospheric LW absorption — > direct radiative constraint from the E (SRF, clear) = 2OLR (clear) geometric requirement — > immediate (instantaneous) negative radiative water vapor feedback.

The typical logic is this: adding CO2 — > increased atmospheric LW absorption — > temperature adjustment — > negative water vapor / cloud feedback.

«When methane makes its way into the upper atmosphere, it is oxidized by a complex series of reactions to form water vapor,» Russell added.

You know the science behind it's called the green house effect when the sun beams down on the earth to provide energy to plants after that it reflects out to space but CO2, H2O (Water Vapor), and AO2 capture these particles and keep them in the earth adding more heat to the earth.

This additional water vapor also absorbs IR and this extra warming gets added to the original warming from CO2 alone.

For a degree of warming, CO2 adds 10 - 15 ppm which may add another couple of tenths of a degree including its own water vapor feedback.

The added carbon dioxide of course will continue to absorb but the reduction of water vapor will keep total absorption constant and as a result this absorption by CO2 is unable to cause any warming.

So their «warming» effect would be almost instantaneous as SST and added atmospheric water vapor.

Even arbitrary scenarios could be constructed, built on reanalyses; for instance, adding 10 % more water vapor on the lateral boundaries of a Type 2 downscaling run.
