And a third found that climate - induced sea - surface temperature anomalies over the northeast Pacific were driving storms (and moisture) away from California, but the warming also caused increased humidity — two competing factors that may produce no net effect.

Total column water vapour has increased over the global oceans by 1.2 ± 0.3 % per decade from 1988 to 2004, consistent in pattern and amount with changes in SST and a fairly constant relative humidity.

I think what Alastair is alluding to is the fact that, say by 2050 when the arctic ocean will conceivably be ice - free in the summer, the atmosphere will have a much higher relative humidity than it has currently because of the open air = water interface, so this will have a magnifying effect beyond just the feedback from increased CO2.

re Gavin @ 223 I know what the mean global temperature is (actually, I don't, see below) but the question was why is this a meaningful metric for looking at changes over time, when you could get the same global mean from very different distributions of temperature (eg increase the poles, decrease the tropics) which would have very different interpretations of energy balance (at least if I am right that humidity matters)?

Taking the slow increase of precipitation with temperature as a given, the more rapid increase of boundary layer humidity implies that the rate of transport of moisture from the boundary layer to higher levels where it rains out must go down.

The condensation level at the top of the boundary layer will prevent this increased humidity reaching further up into the atmosphere, because it will be rained out from the clouds at the condensation level.

I then play a video from Texas Tech University climate scientist Dr. Katharine Hayhoe which she says: «One of the changes we have seen is that the average humidity of our planet has increased by 4 %.

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

Surface measurements of downward longwave radiation A compilation of surface measurements of downward longwave radiation from 1973 to 2008 find an increasing trend of more longwave radiation returning to earth, attributed to increases in air temperature, humidity and atmospheric carbon dioxide (Wang 2009).

So for example, tomatoes suffer extremely from water shortages (in cases of droughts) or increased humidity (in cases of long lasting rain).

The average relative humidity in cities is usually several percent lower than that of adjacent rural areas, primarily because of increased runoff of precipitation and the lack of evapotranspiration from vegetation in urban areas.

This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).

Another paper discusses how atmospheric humidity increased during the recent period of pronounced global warming (from about the late 1970s to the present), with a humidity decrease during the cooling / temperature stagnation period of ~ 1940s to the 1970s:

A slight change of ocean temperature (after a delay caused by the high specific heat of water, the annual mixing of thermocline waters with deeper waters in storms) ensures that rising CO2 reduces infrared absorbing H2O vapour while slightly increasing cloud cover (thus Earth's albedo), as evidenced by the fact that the NOAA data from 1948 - 2008 shows a fall in global humidity (not the positive feedback rise presumed by NASA's models!)

The relative humidity suggests as well that the OLR from the water vapour in the spectral regions where figure 6 - A shows high optical thickness has been slowly increasing, as the source of radiation to the cosmos moved to slightly «lower and warmer» layers.

In recent decades the ITCZ has been migrating north moving it farther away from Easter Island and as that distance increases absolute humidity over Easter Island will necessarily decrease which necessarily means in increasing temperature delta between daytime high and nighttime low.

Measurement of CO2 concentration is always problematic; the «Standard Dry Air» SDA basis of measurement and comparison is at standard temperature and pressure which is a non-existent parameter; and as we are seeing, CO2 is not a well - mixed gas at all and will be defined by, amongst other variables, SH, or absolute humidity; SH can vary from 0 to 5 % by volume of atmosphere; as the SH increases, the absolute amount of other gases, including CO2, decreases; to say therefore that atmospheric concentrations of CO2 have remained stable and not been above 280ppm over the last 650my is fanciful; even if you assume past CO2 levels have not got above 280ppm the range of variation within that limit has been greater than the current increase;

Of course it does not agree with IPCC, who is selling us the message that specific humidity increases in march - step with temperature according to Clausius - Clapeyron to essentially maintain a constant relative humidity (thereby resulting in a major positive feedback from water vapor with warming).

That is what happens when oceans naturally increase their emission of energy and the response of the air is exactly the same whether the warmer ocean surface is a result of enhanced energy emission from the ocean or enhanced energy in the air from another cause such as more humidity or more CO2.

The lower relative humidity and increased temperatures that would result from potential reductions in fog and low cloud cover could increase plant evapotranspiration rates, raise soil water deficits, and accelerate risks of forest fire.

Upper tropospheric humidity is a critical topic in assessing the strength of water vapor feedbacks — knowledge that is essential to understand just how much temperature increase can be expected from doubled CO2.

In the lower atmosphere, the available data points to increasing water vapor content, but because of large variations in local humidity from day to night, from day to day, and from season to season, no - one currently knows exactly how much more water vapor is going into the air (IPCC Working Group 1 Assessment Report 4, Chapter 3, «Observations: Surface and Atmospheric Climate Change», page 273).

It seems the models rely on this increased humidity feedback to amplify the small incremental warming from CO2 to a significant several degrees C.

One study, published in today's edition of the journal Nature, found that the overall increase in worldwide surface humidity from 1973 - 99 was 2.2 %, which is due «primarily to human - caused global warming,» according to study co-author Nathan Gillett of the University of East Anglia, in Norwich, U.K.
