The mean distribution of precipitable water, or
total atmospheric water vapor above the Earth's surface, is shown in Figure 2.
Simulations and observations of
total atmospheric water vapour averaged over oceans agree closely when the simulations are constrained by observed SSTs, suggesting that anthropogenic influence has contributed to an increase in
total atmospheric water vapour.

The U.S. conducted a
total of 67 nuclear tests (pdf)-- some above the
water and some beneath — in the Marshall Islands between 1946 and 1958, when the country halted
atmospheric tests (largely due to Castle Bravo).
... The Earth's
atmospheric methane concentration has increased by about 150 % since 1750, and it accounts for 20 % of the
total radiative forcing from all of the long - lived and globally mixed greenhouse gases (these gases don't include
water vapor which is by far the largest component of the greenhouse effect).
The specific humidity (i.e. «concentration» of
water) is proportional to the ratio of partial pressure of
water vapor to
total atmospheric pressure.
The increased warmth allows the atmosphere to hold more
water vapour so that
total atmospheric density increases and the
atmospheric greenhouse effect strengthens.
Precipitable
water - The
total amount of
atmospheric water vapor in a vertical column of unit cross-sectional area.
Publishing in Nature Climate Change, Melet et al. (2018) study the effect of
atmospheric surges, tides and waves on
total water level rise at the coast.
Non-condensing greenhouse gases, which account for 25 % of the
total terrestrial greenhouse effect, thus serve to provide the stable temperature structure that sustains the current levels of
atmospheric water vapor and clouds via feedback processes that account for the remaining 75 % of the greenhouse effect.

After all CO2 is itself only a tiny portion of
total greenhouse gases so that it can not have any significant long term effect when the
water vapour primarily affecting
atmospheric heat retention is in turn itself but a tiny proportion of global heat retaining capacity when one adds in the vastly greater oceanic heat retaining effect.
If we take a further step and consider the
atmospheric state at a location (or even the global average) with respect to temperature or precipitation, we may observe that physics does not imply any preservation law for temperature (the
total energy is preserved, not temperature) or for precipitation (the
total water balance is preserved, not the rate of precipitation).
This forcing has a particularly strong and direct impact on the surface energy cycle, but interacts with many aspects of the surface and column - integrated
water and energy cycles through dynamical convergence, leading to large diurnal fluctuations in the
atmospheric reservoir of
water vapor and
total dry energy.
An additional smack - down to the CO2 haters is that not only is CO2 very dubious as a significant driver of climate (as opposed to the sun,
water vapor, clouds, and oceans), but man - made CO2 comprises only a tiny fraction — about three percent — of the Earth's
total atmospheric CO2.
Note that this is only part of the story since, as far as we are aware, no one has yet investigated a counterintuitive parallel effect — condensation and precipitation will likely reduce the
total lower
atmospheric concentration of that ubiquitous greenhouse gas,
water vapor, so increasing clear sky radiative cooling.
However, a double check of the diagram shows that it doesn't distinguish between organic and inorganic C in the deep and intermediate ocean, so the
total amount of organic C within the ocean that is available to be oxidized at that rate (using O2 at a rate of 0.011 % of
atmospheric O2 per year) could be larger; however, oxygen depletion in the deeper ocean
water wouldn't pull O2 out of the atmosphere until that
water resurfaced.)
Notice how they downplay its
atmospheric significance by comparing it to the
total water volume on the planet.
