The higher temperatures associated with climate change near the surface are resulting in increased evaporation, leading to more water vapor in the stratosphere which chemically reacting with the ozone — resulting in ozone depletion.

Indeed, there is a clear physical reason why this is the case — the increase in water vapour as surface air temperature rises causes a change in the moist - adiabatic lapse rate (the decrease of temperature with height) such that the surface to mid-tropospheric gradient decreases with increasing temperature (i.e. it warms faster aloft).

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

The water vapor feedback (a generally positive feedback)-- there is an roughly exponential increase in saturation water vapor pressure with increasing temperature, and the relative humidity (at a given vertical level) overall tends not to change a lot globally, though there will be different regional trends associated with shifting precipitation patterns.

First, for changing just CO2 forcing (or CH4, etc, or for a non-GHE forcing, such as a change in incident solar radiation, volcanic aerosols, etc.), there will be other GHE radiative «forcings» (feedbacks, though in the context of measuring their radiative effect, they can be described as having radiative forcings of x W / m2 per change in surface T), such as water vapor feedback, LW cloud feedback, and also, because GHE depends on the vertical temperature distribution, the lapse rate feedback (this generally refers to the tropospheric lapse rate, though changes in the position of the tropopause and changes in the stratospheric temperature could also be considered lapse - rate feedbacks for forcing at TOA; forcing at the tropopause with stratospheric adjustment takes some of that into account; sensitivity to forcing at the tropopause with stratospheric adjustment will generally be different from sensitivity to forcing without stratospheric adjustment and both will generally be different from forcing at TOA before stratospheric adjustment; forcing at TOA after stratospehric adjustment is identical to forcing at the tropopause after stratospheric adjustment).

Furthermore natural global temperature swings alter the natural background greenhouse effect constantly as water vapour held in the atmosphere increases and decreases naturally with changing global temperatures.

This is done by scaling local to global warming and by «coupled linkages» that show how other climate changes, such as alterations in the water cycle, scale with temperature.»

Therefore, the August - Roche - Magnus equation implies that saturation water vapor pressure changes approximately exponentially with temperature under typical atmospheric conditions, and hence the water - holding capacity of the atmosphere increases by about 7 % for every 1 °C rise in temperature.

For large lake ecosystems, these changes have well - documented effects, such as effects on algal production, stratification (change in water temperature with depth), beach health, and fisheries.

Not only that, but since the 1980s, more land area is above water than below it, indicating that tectonics and subsidence / uplift have much more to do with long - term relative sea level than climate or changes in water temperatures do.

This remains to be seen, of course, but it's important to point out that the trospospheric amplification prediction does not originate in the models but in the basic physics of radiative transfer in combination with the Clausius - Clapeyron relationship describing the change in atmospheric water vapor as a function of temperature.

FOR IMMEDIATE RELEASE An extensive new study by climate impact researchers warns that humans will struggle to cope with drastic and rapid changes to the planet unless greenhouse gas emissions rates are cut now London, 8 October − Allowing the Earth's temperature to rise by more than 2ºC will see dramatic changes in vegetation across the planet and expose a billion more people to severe water scarcity, according to new research.

Given the vast pool of very cold water in the deep ocean, even modest changes in the rate it exchanges heat with the surface can produce large changes in temperature without any change in the planetary radiative balance.

But keep in mind when water freezes high in the atmosphere there's a fair amount of latent heat released when water at freezing point becomes ice at freezing point (lots of heat released with no change in temperature).

What is left is that insolation, in the morning, with no change in temperature, is continuously converting airborne water colloid to WV at the rate of 2400 W / g (m ²); with continuous reversion back to airborne water colloid releasing that same 2400 W / g (m ²) to space via EMR in the nighttime.

But, just in case you were semi-serious: With oceans covering 70 % of the earth's surface, you could never change atmospheric humidity — water vapor pressure is a function of atmospheric temperature, increasing as temperature rises.

The largest changes of water vapor with temperature occur in the boundary layer and the upper troposphere.
