In a warmer world,
air holds more water vapor, so when cloud conditions are right for that vapor to form droplets, more precipitation falls.
First, warm
air holds more water vapor than cold air — and the rising air temperatures since the 1970s have caused the atmospheric water vapor content to rise as well.
For example,
the air holds more water vapor as temperature rises, which is a positive feedback magnifying the climate response, because water vapor is a greenhouse gas.
Warmer
air holds more water vapor than colder air, so global warming will make the lower atmosphere wetter.
(A third of summer sea ice in the Arctic is gone, the oceans are 30 percent more acidic, and since warm
air holds more water vapor than cold, the atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.)
Warm
air holds more water vapor than cold air does, so the air is more humid than a few years ago.
Warmer
air holds more water vapor, and that extra moisture leads to heavier storms.
Climate change contributes to increased flooding because warmer
air holds more water, leading to stronger and more frequent precipitation events.
The «rules of physics» tell us that warmer
air holds more water vapor, yes, and how much water is in the troposphere is mostly controlled by this rule.
Lets confuse the issue more: «One of the fundamental aspects of global warming is that it increases the amount of moisture in the atmosphere, because warmer
air holds more water vapor.»
I can certainly see that SOME CO2 level would do that, but everything I have read so far about Antarctic says that in a somewhat warmer climate, which we will have in Antarctica soon, Antarctic as a whole will get more snowfall, hence more retention of ice, because warmer
air holds more water vapor, even if the increase in warmth is merely from minus 40 C to minus 35 C.
Warmer
air holds more water vapour so that warmer air will extract more vapour from the ocean surface thereby cooling the ocean surface..
Warmer
air holds more water vapor than colder air, so the amount of water vapor in the lower atmosphere increases as it is warmed by the greenhouse effect.
So a local spike in precipitation releases a lot of heat — but as the heat increases, this negatively affects the vapor - > water transition (precipitation, or raindrop formation), since warm
air holds more water then cool air — and so the limit on precipitation vis - a-vis the radiative balance of the atmosphere appears.
(skipped evaporation of water — warmer
air holds more water — column has been measured etc..
«Warm
air holds more water vapor,» Titley notes.
(yes I know that warmer
air hold more water so their is a feedback, but not enough to be a self perpetuating cycle).
Not exact matches
Air can
hold about 7 percent
more water for every degree Celsius increase in temperature, Kossin explained.
Warmer
air increases the evaporation rate of
water, and for every degree Celsius increase in temperature, a parcel of
air can
hold 7 percent
more water.
The grant was also used to
hold workshops and establish
air and
water quality demonstration sites in
more than 10 vineyards throughout California to showcase innovative technologies and practices.
In this sense, rewilding
holds the potential to stabilize far
more than natural areas in peril: it can enhance and protect national security by sequestering carbon and safeguarding fresh
water, fertile soils, cleaner
air.
Heaving
water holds 40 times
more energy than
air moving at the same speed, and sea states change
more slowly than breezes, making it easier for utilities to predict the availability of energy.
Warmer
air can
hold more water vapour that is eventually rained out, and warmer
water holds more energy for a hurricane to draw its power from.
By analyzing global
water vapor and temperature satellite data for the lower atmosphere, Texas A&M University atmospheric scientist Andrew Dessler and his colleagues found that warming driven by carbon dioxide and other gases allowed the
air to
hold more moisture, increasing the amount of
water vapor in the atmosphere.
«Simple physics tells us that warmer
air can
hold more water vapour.
After all, warmer
air can
hold more water, and some research suggests global warming could increase California's average rain and snowfall.
The warmer
air will be able to
hold more water.
In addition, it was already known via the Clausius - Clapeyron relation, that warmer
air can
hold more water vapour: the amount is about 7 %
more per degree Celsius of warming.
The warming due to
water vapor helps the
air hold water, but in the Earth's orbit, it is not actually sufficient to keep the
air warm enough to keep the
water it already has — so you go into the death spiral, with a bit of cooling, less
water, then
more cooling, and so on to Snowball.

Cats need
water all 4 seasons;
more so in winter, as cold
air holds less moisture, and indoor heating dries out their skin.
It is true, however, that most heavy snowfalls occur with relatively warm
air temperatures near the ground — typically 15 °F or warmer since
air can
hold more water vapor at warmer temperatures.»
As it gets warmer, a kilogram of
air can
hold more grams of
water before condensation starts to occur.
That makes the land
more moist, because cold
air holds less
water.
Feedbacks: the warmer the
air the
more water it can
hold before raining it out.
Even given these stipulations, it is very, very hard to blame this present flooding on the warming given logic like Trenberth's, that warmer
air can
hold more water vapor.
The loss of ice cover not only means that
more open
water will be around to directly warm the
air into the Arctic night, but that
more water vapor will be around to
hold heat in.
Cold
water may
hold more CO2, but the amount it absorbs from the
air depends on how saturated it already is.
First is that warmer
air can
hold more water vapor, leading to torrential rains in coastal regions that last longer than usual.
It is quite different from the
more familiar relative humidity, which is the amount of
water vapor in
air relative to the amount of
water vapor the
air is capable of
holding.
It is generally accepted that a warmer climate will result in
more water evaporating from the land and sea and therefore resulting in a higher level of
water in the atmosphere, partly because the warmer the
air is the
more water it can
hold.
As warmer
air can
hold more water vapor, which is also a greenhouse gas, this will amplify the effect.
If it is extreme wet, it is 100 % proof of AGW as warmer
air can
hold more water, hence
more intense precipitation.
The Clausius - Clapeyron equation specifies that as the temperature of the
air rises the ability of the
air to
hold more water vapor rises exponentially.
The notion of an H2O positive feedback (which probably is present on a clear day) is squashed by this process.While warmer
air can
hold exponentially
more water vapor, presumably increasing greenhouse effects (an process the IPCC hangs its collective hat on), it is also this exact same property that vastly improves the chances of convective and phase change heat transport by thunderstorms.
But
air temperature would increase significantly, and entire atmosphere could
hold many factors
more water, so in about century, all ice caps could be gone.
And warmer
air can
hold more water in vapor form which means less clouds.
Not to mention the fact that the
air holds 1.4 %
more water at a 2 degree increase, so you'd see
more clouds and
more rainfall in the foodbelt.
That is based on real (be it upscaled) measurements, and measurements of how much
more water warmer
air can
hold.
And
more importantly, the amount of
water vapor
air can
hold depends upon temperature — most of us will have experienced this, in the form of the «fall» of dew during the natural cooling of a summer's evening.
