Water comes into play because CO2 driven warming will
put more water vapor in the atmosphere, because greater heat will vaporize more water.
We know that more open water will
put more water vapor in the air, and increase the sunlight absorbed each summer, both of which will lead to yet more warming.
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.
According to this scenario, warming temperatures heat up the surface of the oceans, increasing evaporation and
putting more water vapor into the atmosphere.
Not exact matches
Given the sensible & latent heat transport # s above, it doesn't seem very plausible for convection & conduction to play a role comparable to radiation (especially because latent heat transport also
puts more moister in the upper atm, and that
water vapor feedback traps
more radiation).
CHris O» What you are saying
put «pretty simpl [y]» is «the warmer the oceans and the atmosphere [get] the
more water vapor [the]
more greenhouse effect from
water vapor in the atmosphere.»
in addition another thought they do not bring up is under sea volcanic activity may heat up the oceans, increasing the amounts of
water vapor put into the atmosphere which could result in
more snowfall and eventual glaciation.
As the climate warms,
more water vapor is
put into the atmosphere, which enhances the greenhouse effect.
A simple example, increased
water vapor [a GHG], leading to much
more clouds and greater albedo means that
more energy will be reflected to space meaning that the effective heat source drops in intensity hence the temperature must fall back or as Lucia would
put it, fails to go up any
more [She does not believe feedbacks can be ultimately negative].
In less than a year... It is likely as explained a combination of gradual GHG heat build up, (ice melting) finally triggering
more specific humidity, a greater
water vapor presence, especially due to open
water of the
more open Arctic Ocean Your solar explanation fails and should be
put to rest.
Or
put another way, if there is so much
water vapor around (3 % vs only 390ppm for CO2), and
more GHGs means
more warming, why does the GHE stop at 33C instead of continuing until all the
water vapor absorbs a photon OR asked another way, who says that all the
water vapor caused by the added CO2 will absorb a photon to cause
more GHE warming?
