Warmer water means
more water vapor rises up into the air, and what goes up must come down.
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.
Not exact matches
But by the same token, as global temperatures
rise, the atmosphere can hold
more water vapor.
Prior to an eruption, gases —
water vapor, carbon dioxide, and sulfur dioxide — bubble out of the magma as it
rises, adding
more pressure to the volcanic system, she explains.
Rising temperatures would put
more water vapor into the atmosphere, which then rains out, increasing the amount of dissolved carbon dioxide that chemically interacts with the rocks.
The spacecraft's sensitive spectrometer was able to register the chemical signatures not only of
water vapor but also of hydrogen cyanide, carbon monoxide, and carbon dioxide — all precursors of the
more complex molecules that scientists think eventually gave
rise to life on Earth.
They expected that
rising temperatures would produce
more water vapor, leading to
more snowfall and
more ice.
Climate scientists know that the intensity of extreme precipitation events is on the
rise because there's
more water vapor in the atmosphere caused by higher global and sea temperatures.
They strengthen over warm
water, such as that around Florida, and
rising temperatures create
more water vapor in the atmosphere, intensifying rainfall.
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.
More water vapor from
rising temperatures will further increase the temperature
rise.
This argument hinges on the contention that
more water vapor means greater density of
water droplets in the active
rising updraft of the storm clouds.
So as
more CO2 gets pumped into the atmosphere the temperature
rises, which causes
more water to evaporate (as you accurately state), increasing the concentration of
water vapor in the atmosphere — which heats the atmosphere even
more, causing even
more water vapor to enter the atmosphere.
16 (DBB) If
more water vapor leads to
more precipitation then
water vapor will act as a negative feedback on
rising global temperature.
This additional
rise in temperature will result in still
more water vapor which will raise the temperature still
more, but by a smaller amount.
This means that every 2 degree potential
rise in temperature of the surface layer causes an 8 fold
rise in the amount of
water vapor release hence buckets
more clouds and massive albedo reflection keeping the temperature from riding.
Because the new precise observations agree with existing assessments of
water vapor's impact, researchers are
more confident than ever in model predictions that Earth's leading greenhouse gas will contribute to a temperature
rise of a few degrees by the end of the century.
SSTs have
risen by 0.5 — 0.6 °C since the 1950s, and over the oceans this has led to 4 %
more water vapor in the atmosphere since the 1970s (Trenberth et al. 2007).
Dan Pangborn: The still -
rising water vapor (WV) is
rising at 1.5 % per decade which is
more than twice as fast as expected from
water temperature increase alone (feedback, engineering definition).
That's because the entire environment in which these storms form is changing: Warmer oceans means
more water vapor is available to fuel the storms» intensification, and
rising sea levels mean
more coastline will be inundated when they hit.
A
rising planetary temperature sets in motion all sorts of secondary effects that can boost the temperature even higher — effects like melting Arctic sea ice,
rising levels of heat - trapping
water vapor in the atmosphere, and... Read

If it is true that a temperature
rise will cause
more water vapor, which will cause
more temperature
rise, and
more water vapor yet again, one would expect temperatures to continue to
rise after 1998, and result in a run - away effect.
Water vapor is an even
more powerful greenhouse gas than carbon dioxide and this caused temperatures to
rise even
more.
However, a vicious cycle exists with
water vapor, in which as
more CO2 is emitted into the atmosphere and the Earth's temperature
rises,
more water evaporates into the Earth's atmosphere, which increases the temperature of the planet.
As the temperature of the air
rises, it can hold
more water vapor.
When temperatures
rise there may be
more water vapor evaporated into the Atmosphere and that may result in
more clouds and, if clouds have a net cooling effect (as I think they do) that may reduce the rate of incoming shortwave radiation and thus reduce incoming energy rates such that the temperatures will not
rise as high.
It's kind of like considering
water vapor as a gas expanding into
more space that it is given when it is warmer because the condensation level
rises higher.
-- Solar Irradiance changes (let's say about 2 % and
more)-- Now, world heats up temperature
rises, ocean releases CO2 and
water vapor as it warms (even with lag)-- Temperature
rise even father, CO2 and
water vapour are released until a natural balance limit is reached (otherwise you could «over-satisfy» the athmosphere)
In light of trends showing a likely 3 °C or
more global temperature
rise by the end of this century (a figure that could become much higher if all feedback processes, such as changes of sea ice and
water vapor, are taken into account) that could result in sea level
rises ranging from 20 to 59 cm (again a conservative estimation), Hansen believes it is critical for scientists in the field to speak out about the consequences and rebuke the spin offered by pundits who «have denigrated suggestions that business - as - usual greenhouse gas emissions may cause a sea level
rise of the order of meters.»
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.
As the temperature
rises,
more water vapor enters the atmosphere and multiplies CO2's greenhouse effect; the Intergovernmental Panel on Climate Change notes that
water vapor may «approximately double the increase in the greenhouse effect due to the added CO2 alone.»
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.
That's because for every 1 °F
rise in temperature, the atmosphere can hold 4 percent
more water vapor.
