Four and a half billion years after its birth, the shrouded planet is much too hot to support the presence of
liquid water on its surface because of its dense carbon dioxide atmosphere and sulfuric acid
clouds, which retain too much radiative heat from the Sun through a runaway greenhouse effect.
When the relative humidity reaches 100 %, the
water vapor condenses into
liquid water droplets and the
clouds begin to form.
The

For instance, it's only recently that separate diagnostics for
cloud liquid water and

Similarly, we have not been able to tell how much of the aerosol is capable of interacting with
liquid or ice
clouds (which depends on the different aerosols» affinity for
water), and that impacts our assessment of the aerosol indirect effect.
But the more general statement that I used, «increasing the endurance of
cloud liquid water», does not always translate into longer
cloud lifetimes, particularly in the widespread areas of nearly overcast marine stratocumulus which dominate considerable areas of the globe.
[9] The fundamental dispute is about
water in the atmosphere, either in the form of
water vapour (a gas) or
clouds (
water in
liquid form).
It all depends on how much, and a t what altitudes, latitudes and times of day that
water is in the form of a gas (vapour) or a
liquid (
clouds).
The heat from this radiative forcing then goes back down, through the atmospheric CO2 and
water vapor, through the
clouds, and down to the surface where it has sex with
liquid water.
While there are some similarities between the approaches, an important difference is that the slab - ocean approach allows surface and MBL temperatures to adjust to the energetic perturbation: positive energetic forcing of the surface leads to warming, weakens the inversion, and reduces low -
cloud cover and
liquid water path (LWP).
Less well appreciated is that
clouds (made of ice particles and / or
liquid water droplets) also absorb infrared radiation and contribute to the greenhouse effect, too.
I am fairly certain that the variable is «
cloud liquid water» not «

It originates in

water vapor in the atmosphere condenses directly into ice without going through the
liquid stage.
The main difference between H2O and CO2 (apart from the numerical differences of their specific physical properites such as degree of freedom, thermal capacity, physical mass, etc) in terms of their effects on the atmosphere is that
water is capable of condensing into
liquid to form
clouds and readily and rapidly moves between surface and atmosphere, daily, seasonally, annually and on even greater time scales, but CO2 does not liquify in the biosphere and transfers over mostly long time periods between surface (primarily oceans, seas, etc) and the atmosphere.

In such a

As a result of changes in rainfall production, the amount of
