Basically Miskolczi has looked at the thermodynamics of water vapor and CO2 and found that they interact such that, as CO2 rises, absolute humidity decreases, creating a relatively constant heat - trapping effect, if not a decreased effect with an increasing proportion of CO2.

After allowing for humidity and rainfall, they found that «aerosol optical thickness» — a measure of the concentration of atmospheric particles — decreased by only 10 to 15 per cent compared with the same periods in 2002 to 2007 (Geophysical Research Letters, in press).

«The direct heat generated by burning biomass is significant and contributes to cloud evaporation by decreasing relative humidity,» Jacobson said.

«We found that relative humidity generally has been both increasing in the Pacific Northwest and decreasing in the desert southwest over the last 30 years, reinforcing the patterns of winter melt in the Pacific Northwest and sublimation in the southwest.»

At the risk of talking out of my ass, I think the main effect of razing tropical rainforest is to decrease transpiration, which decreases relative humidity, which decreases overnight temperatures.

In the central United States, for example, observational data indicate that rainfall increased, surface air temperature decreased, and surface humidity increased during the summer over the course of the 20th century concurrently with increases in both agricultural production and global GHG emissions.

Results of both regional climate model simulations and observational analyses suggest that much of the observed rainfall increase — as well as the decrease in temperature and increase in humidity — is attributable to agricultural intensification in the central United States, with natural variability and GHG emissions playing secondary roles.

Across Montana, conditions that lead to high fire risk (i.e., likelihood of occurrence) are becoming more common: seasonal maximum temperatures are increasing, snowmelt is occurring earlier, minimum relative humidities are decreasing, and fuels are becoming drier (Jolly et al. 2015; Seager et al. 2015).

Decrease your indoor humidity to below 50 % when possible using dehumidifier.

So high heat and humidity cause a large loss of fluid as the body fights to cool itself in turn decreasing performance.

When humidity is low, evaporation increases, when humidity is high, evaporation decreases and less cooling occurs.

We have a while over here, but at least the humidity has decreased.

As much as I'm longing for fall and a decrease in humidity, I don't think it's time for sweaters just yet (even the short - sleeved variety).

If the tank is kept full, there is less space inside it to collect condensation, which can help decrease this effect, but it also depends on the humidity where the gas is stored.

Cats do not appear to be affected by conformational differences of the pinnae, as seen with the Scottish fold.3 Excessive hair in the canal, as seen in poodles and schnauzers, can also decrease ventilation and form hair mats that retain debris and create obstructions.7 Shar - peis have stenotic canals that may be predisposed to higher humidity levels and secretions, leading to overgrowth of normal microbial inhabitants.1, 7 An increase in glandular tissue can lead to an increase in cerumen production and debris accumulation, which seems to be more common in cocker spaniels, springer spaniels, and Labrador retrievers.1, 7

First of all it is important to note that even pure greenhouse gas forcing will lead to a slight decrease in surface solar radiation (due to the concurrent increased humidity) and potential cloud feedbacks.

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)?

Both fire hazard indices increased over this period, as a consequence of increasing mean daily maximum temperature and decreasing minimum daily relative humidity.

Now since relative humidity remains roughly constant at the ocean surface and the air's capacity to hold water increases with temperature, relative humidity will actually decrease over land, particularly as one enters the continental interiors.

Absence of CO2, humidity increases, goes to saturation level - > evaporation decreases.

Radiosonde humidity data shows decreasing RH around the world.

The long - term NOAA record of tropospheric humidity from radiosondes and satellites shows that water vapor content (specific humidity) has decreased with warming.

Wouldn't that * decrease * the humidity differences?

Similarly, a colder climate with generally decreased humidity q O could be closer to the critical threshold, which might be the reason for less - stable monsoon circulations during glacial periods.

The 2009 State of the Climate Report of the US National Oceanic and Atmospheric Administration (NOAA) tells us that climate change is real because of rising surface air temperatures since 1880 over land and the ocean, ocean acidification, sea level rise, glaciers melting, rising specific humidity, ocean heat content increasing, sea ice retreating, glaciers diminishing, Northern Hemisphere snow cover decreasing, and so many other lines of evidence.

Perhaps the «unexplained» increase in late 20th century temperature has simply been a response to decreasing humidity over the oceans?

The absolute humidity will be largely set by the oceans, so water vapor and will increase but relative humidity over land will largely decrease, resulting in less precipitation than one would otherwise expect, given Clausius - Clapeyron and a constant residence time.

Because water vapor is the most plentiful greenhouse gas, this decrease in average humidity would cool things globally.

The latest research suggests this is due to decreased humidity (sorry don't have time to find the link), as a result of deforestation on the plains below, nothing to do with CO2.

Most of the decrease is caused by a decrease in the specific humidity in the upper troposphere but hey... why mention that when you can scare the beeJesus out of people with pseudo-science.

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

An increased greenhouse effect due to humidity, CO2, aerosols or clouds is expected to produce a relative increase of the minima with respect to the maxima and a decrease of the diurnal range.

Evaporation increases with rising surface temperature, decreasing relative humidity, and increasing surface wind speed.

Warming is largest in the NE, but the decrease in relative humidity is larger in the south.

Using a simple physical model, O'Gorman suggests that this is due to the balance between two competing effects caused by the warming: increasing moisture available for humidity and the decreases in the fraction of precipitation that falls as snow.

-LSB-...] There have been no long - term changes in dewpoint temperatures or specific humidity but rather there has been a decreasing (1947 — 79) and then an increasing (1980 — 2010) trend in both variables.»
