The sinking is mainly driven by the saltiness of the water, which is
affected by evaporation of fresh water from the surface or, particularly in the Arctic, freezing seawater which leaves salt behind in the water beneath the ice.
Not exact matches
Humans alter that hydrological cycle through water use demand - irrigation being a large use - and cause changes in water supply
by affecting evaporation and runoff.
Why It Matters: The Earth's water cycle is
affected by energy exchanges via
evaporation, transpiration, condensation, and precipitation, to name a few.
Radiation biases are largely
affected by cloud simulations, while EF bias is largely
affected by soil moisture modulated
by seasonal accumulated precipitation and
evaporation.
Key facts about the lesson are: The content covered
by the lesson are; the water cycle as a system, the states of water and the proportion of water in different states, features / components of the water cycle (transpiration, percolation etc), flows and stores in the water cycle, factors that
affect the rates of precipitation, condensation,
evaporation, infiltration, percolation and interception in the water cycle.
The argument isn't actually as firm a constraint as generally believed, since the infrared radiative cooling of the atmosphere is
affected by the temperature difference between air and the underlying surface, which can adjust to accommodate any amount of
evaporation Nature wants to dump into the atmosphere (as shown in Pierrehumbert 1999 («Subtropical water vapor...» available here)-RRB-.
As you know, salinity
affects evaporation and / or may reflect an influx (or lack) of fresh water (
by precipitation, riverine, or runoff).
I understand that their
affect on albedo is unfortunate, and their
affects on transpiration /
evaporation / cloud cover are ambiguous, but aren't these outweighed
by their sequestration benefits, especially at low - latitude or even low - ish latitued (e.g., Israel)?
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.
By modifying the
evaporation and precipitation rate, the global warming will probably
affect the hydrous climate balance and therefore the Tunisian water resources.
This rapid change might
affect the availability of water resources
by altering the rates of
evaporation and precipitation.
He also says I do not specify the method
by which
evaporation affects climate sensitivity.
We find that the reported discrepancy can be traced to two main issues: (1) unforced internal climate variability strongly
affects local wetness and dryness trends and can obscure underlying agreement with WWDD, and (2) dry land regions are not constrained to become drier
by enhanced moisture divergence since
evaporation can not exceed precipitation over multiannual time scales.
Both properties and distribution are
affected by continuous
evaporation and condensation processes of semi-volatile organic material which must be simulated.
The standard rebuttal is «no no no, impinging LWR MUST only
affect evaporation» but,
by way of the RC article you cited, we know that this is not the case empirically.
The IPCC summary is deeply flawed as a scientific document and as I have explained in other recent articles it appears impossible for increased levels of atmospheric CO2 at the puny levels caused
by mankind to
affect the characteristics of the atmosphere enough to significantly enhance the greenhouse effect and even if it could do so then any such effect would be quickly neutralised
by the primary solar / oceanic driver and the oceans acting in conjunction with
evaporation, condensation and atmospheric convection (which includes clouds and rain).
The amount of direct heat on earth can be given
by this equation: 100 — energy deflected (ca. 30 %)-- energy used for
evaporation (ca. 23 %) = (ca. 47 %) What
affects earth's albedo?
Warm air can not significantly
affect the oceans due to the huge difference in thermal capacities and
by the effect of
evaporation which removes unwanted energy to latent form as necessary to maintain the said equilibrium.
It's also important to point out, however, that although changes in
evaporation, convection and latent heat transport, humidity, water vapor, clouds, and other quantities
affect the surface temperature response, they are excluded from the Planck («no - feedback») response
by definition.
