Here's a better idea for this so - called «governor» to consider: Take a look at the research done by your alma mater, Texas A&M, on global warming and the effect it will have on Texas (higher temps and greater stress on water through decreased rainfall and increased evaporation)... then stop poopooing the efforts to mitigate the effect humans are having on climate change.

The excessive heat increased the rate of water loss by evaporation and caused precipitation to shift from snow to rain, leaving a meager snowpack and parched reservoirs.

That's because tropical forests are so good at cooling their surroundings by increasing the evaporation of water.

«Higher temperatures exacerbate the drought by increasing evaporation and transpiration,» Westerling said.

«But because precipitation has to be balanced by evaporation, we expect a [corresponding] increase in dry regions,» Marvel said.

During the dry season, with no fog layer to reflect sunlight, the smaller cloud cover allows plants to receive much higher radiation, increasing evaporation and photosynthesis rates, another process missed by the GCMs.

The apparent rise in evapotranspiration — the process by which water is transferred from the land to the atmosphere by evaporation from plants and soil — is increasing potential drought risk with rising temperature trends, especially during periodic drought cycles that have been linked with strong El Nino events.

Collectively, these data show general increasing trends in both plant growth and evaporation with recent climate change mainly driven by vegetation greening and rising atmosphere moisture deficits.

In addition, his own fieldwork, published last year, indicates that increased evaporation of the Indian Ocean caused by global warming has actually caused the sea level there to fall 30 centimeters in the past few decades.

While an increase in the amount of radiation the Earth receives by trapping outgoing IR would increase surface temps, would the increased surface temp not increase the convection and evaporation rates introducing a negative feedback?

However, in many of the same places, actual evapotranspiration inferred from surface water balance exhibits an increase in association with enhanced soil wetness from increased precipitation, as the actual evapotranspiration becomes closer to the potential evaporation measured by the pans.

Alarmists have drawn some support for increased claims of tropical storminess from a casual claim by Sir John Houghton of the U.N.'s Intergovernmental Panel on Climate Change (IPCC) that a warmer world would have more evaporation, with latent heat providing more energy for disturbances.

To start, a warmer atmosphere creates more evaporation — for every 1 °F of warming, the saturation level is increased by about four percent.

Therefore while an increase in evaporation may limit the increase in temperature (by your argument), it can not prevent there being an increase.

The layer will also gradually increase its humidity by evaporation of the ocean or lake surface, as well as by the effect of cooling itself.

This additional precipitation is sustained by more energy leaving the surface by evaporation — that is, in the form of latent heat flux — and thereby offsets much of the increase in longwave flux to the surface.

If surface temperatures spike, and the ground is wet, evaporation rates increase, reducing the temperature by latent heat transfer.

Hatun et al. examined the possibilities that [i] a change in rain falling over the ocean (freshens the water) and evaporation (increases the salinity by removing water and leaving salt behind), [ii] increased salinity in the sub-tropical gyre (in the main part of the North Atlantic), [iii] increased salinity in the sub-polar gyre, or [iv] dynamical changes in the relative contributions from the two gyres could explain the high salinities in the in - flow regions.

There is so little understanding about how the ocean parses its response to forcings by 1) suppressing (local convective scale) deep water formation where excessive warming patterns are changed, 2) enhancing (local convective scale) deep water formation where the changed excessive warming patterns are co-located with increased evaporation and increased salinity, and 3) shifting favored deep water formation locations as a result of a) shifted patterns of enhanced warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which transport these enhanced ocean features to critically altered destinations.

The idea of an evaporation thermostat was proposed in the 1970's by Newell, and was based on erroneous reasoning confusing correlation with causation; when one does the physics, one finds that evaporation increases the air - sea coupling, but can't prevent a warming if the atmosphere itself warms.

Ian, looking at the projections it certainly appears that increased evaporation plays a bigger role than decreases in rainfall, but of course the two interact, and the reduction in streamflow is larger again (commonly by a factor of three) than the reduction in rainfall net of evaporation.

For every degree C rise in temperature the atmosphere increases its moisture content by 7 % stemming from added oceanic evaporation.

Researchers project a combination of higher temperatures, increased evaporation and reduced precipitation that could, in 70 years, increase burned areas in California by up to 125 percent.

Increase global wind speed by one kph and it alters critical dynamic mechanisms, including evaporation and transport of energy.

The Fifth Assessment Report, issued by the United Nations Intergovernmental Panel on Climate Change (IPCC) in 2013, synthesized the available scientific studies and reported that increases in evaporation over arid lands are likely throughout the 21st century.

Any extra warmth generated in the atmosphere by CO2 or any other trace gas will quickly be neutralised by the hugely greater effect of the oceans in so far as it has not already been dispersed by increased radiation to space, evaporation, convection, condensation and rainfall.

In the Central Plains, drying would largely be caused by the same temperature - driven increase in evaporation.

These methods have been significantly improved by fully coupling the hydrologic cycle among land, lake, and atmosphere.94, 95 Without accounting for that cycle of interactions, a study96 concluded that increases in precipitation would be negated by increases in winter evaporation from less ice cover and by increases in summer evaporation and evapotranspiration from warmer air temperatures, under a scenario of continued increases in global emissions (SRES A2 scenario).

Water levels are influenced by the amount of evaporation from decreased ice cover and warmer air temperatures, by evapotranspiration from warmer air temperatures, and by potential increases in inflow from more precipitation.

I had stated that globally the rate of evaporation and precipitation increase at the same rate as the humidity of saturation, that is, by 8 % per 1 °C based on a roughly constant residence time, but this is false:

And even if rainfall decreases only slightly from today's levels, evaporation typically increases as temperatures rise, so Namibia is likely to become even drier.9 As water becomes scarcer, the range and number of wildlife supported by Etosha and other national parks could decline.9

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

He supported his climate argument by referring to Parmesan's faulty Edith's checkerspot butterfly studies and argued that increased evaporation from the oceans was «amplifying the warming in the highlands relative to the lowlands.»

Where did I write that, outside of the tropical Pacific, a rise in SST anomalies associated with an El nino event was caused by with an increase in evaporation?

This increases absorbed IR by a factor of 5, offset in the hind0 - casting by exaggerated cloud albedo, hence evaporation and heating rate is artificially increased.

While this is certainly a true statement, it does not follow that we should increase the frequency and magnitude of water resource stress by increasing evaporation, drought frequency, water loss from plants, etc., as the USGCRP report notes will occur as human - induced climate change increases.

Drought is expected to increase in frequency and severity in the future as a result of climate change, mainly as a consequence of decreases in regional precipitation but also because of increasing evaporation driven by global warming1 — 3.

Water resources, already over-tapped in many areas, will become even scarcer as a result of increased evaporation and snowmelt caused by higher temperatures, affecting agriculture, hydroelectric power plants, and water availability in growing cities such as Phoenix and Las Vegas.

It is based upon a small initial increase in temperature caused by CO2 and a large theoretical amplification of that temperature increase, primarily through increased evaporation of water.

There isn't enough extra power supplied by a doubling of CO2 concentration to do that, if the evaporation rate increases 11 %.

Drought is primarily driven by a lack of rainfall, but warmer temperatures can exacerbate drought impacts by increasing evaporation.

In another study by Elguindi and Giorgi (2006), the levels in the Caspian Sea are estimated to drop by around 9 m by the end of the 21st century, due largely to increases in evaporation.

However there would then be more conduction, convection and on Earth more evaporation from the surface for an increased upward energy flow which would work to maintain the lapse rate set by sun and pressure.

The theory is that increasing CO2 will cause a small bit of warming and this will increase evaporation rates (which occur fastest in the tropics) and dumps more water vapour in the atmosphere (water vapour is by far a more potent greenhouse gas than CO2) and this feedback amplification is meant to continue until Earth settles down and finds a new equilibrium temperature.

If the radiative channel becomes more restricted by rising CO2 evaporation can increase instead of temperature in response to get more thermal energy through the troposphere.

As the temperature increases, the water vapor pressure (hence by inference the water evaporation rate on non-dry surface) increases supralinearly; that is, a 1K increase from 288 K is much less than a 1K increase from 308K.

So, overall there is more natural warming caused by increasing maxima causing more evaporation and more condensation, at the same time.

But, when it does so it leaves the surface temporarily warmer and so evaporation increases, as does diffusion which is followed by convection.
