At the same time, sea levels rise, creating more water surface area for
more evaporation of water that becomes fresh water for... more vegetation.
For the same reasons, the loss of glaciers in the mountains create hotter rocks and
more evaporation of the water that remains.

Above all else, they will have to consider whether they can any longer justify using

more evaporation and increase
water demand, as has happened with this drought.
Another process knows as a «runaway greenhouse» occurs due to the increased greenhouse effect

more warming.
Not sure and often, heat drying is

Recent record snowfall months have coincided with unusually warm

However, with me at least, a bit part
of the deal is the increased acidity reducing fish harvests,
water shortages, droughts severely reducing crops (sure —
more rain, but
more over the ocean, less on land — and with greater
evaporation before the
water trickles to a dry stream bed), increased heat reducing rice production and other heat sensative crops, the heat waves, etc..
(I think that an anomalously warm ocean surface heated from below would lead to
more evaporation, and the additional
water vapor would give a positive greenhouse effect that would partially offset the effect
of a drop in greenhouse gas concentrations.)
The increased area
of warm
water on the surface allows the tropical Pacific Ocean to discharge
more heat than normal into the atmosphere through
evaporation.
And once wide swaths
of tree are cut, large land areas lose their shade cover, resulting in
more evaporation from the soil, further reducing
water flows.
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.
But now the risk
of fire is exacerbated by climate change, which heats air (stoking stronger winds) and
water (leading to
more evaporation and hence stronger precipitation events).
I guess we need a laboratory test to see how

With the Earth known as the «
water planet» because
of over 70 %
of the globe covered by deep oceans, warmer temps directly result in
more evaporation of the ocean
water into the air - clouds.
The persistent upwelling
of cold
water in the eastern tropical Pacific would have reduced cloud cover there, via reduced oceanic
evaporation, and thus allowed
more of the sun's energy to enter the tropical ocean - this would have aided the ocean warming process, as generally the case when the tropical ocean is cooler - than - normal.
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
Slopes by angle can expose
more or less volume
of water to
evaporation or flooding depending on degree
of the slope to the height
of water being displaced.
Open
water emits
more infra - red energy to space and
evaporation of surface
water in the windy Arctic region will remove substantial amounts
of heat from the surface.
The lack
of»

more water in Arctic ocean without ice cover as» insulation» - >
water absorbed extra coldness and the currents brought extra coldness in North Atlantic = above the ocean is colder = less
evaporation - > less
water vapor produced - > less moisture going west from central Atlantic.
LIA wasn't GLOBAL cooling; but colder in Europe, north America — because Arctic ocean had less ice cover - > was releasing
more heat / was accumulating - > radiating + spreading
more coldness — currents were taking that extra coldness to Mexican gulf — then to the Mediterranean — because Sahara was increasing creation
of dry heat and evaporating extra
water in the Mediterranean — to top up the deficit — gulf stream was faster / that was melting
more ice on arctic also as chain reaction — Because Mediterranean doesn't have enough tributaries, to compensate for the
evaporation deficit.
Heat =
more evaporation, which =
more rain, which would, or should allay the fears
of the alarmists, yet, inexplicably, they are still afraid
of water going away.
And even though on average
more warmth will mean
more evaporation, and therefore
more water vapour in the atmosphere and
more precipitation in some
of those zones that already have ample rainfall, the pattern could be different in the arid lands.
Note 1: A simple hotspot explanation summarized from this article: Increasing CO2 levels causes atmosphere to warm; then atmosphere causes Earth's surface to warm; warming
of oceans cause
evaporation; increased
evaporation leads to
more water vapor in the upper troposphere;
water vapor is a powerful greenhouse gas that warms the atmosphere even
more (positive
water vapor feedback); the Earth's surface warms even
more; and then auto «repeat and rinse» until Earth's oceans boil, per an «expert.»
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.
(right) With the transition from dimming to brightening (1980s — 2000s), the enhanced greenhouse effect has no longer been masked, causing
more rapid warming, stronger
evaporation / LH, and an intensification
of the
water cycle.
These effects are relatively well understood in the lowest level
of the atmosphere, the troposphere, where increased warming leads to greater
evaporation, causing
more water vapour and so further warming, although this is offset to some extent through the formation
of clouds that reflect incoming sunlight back into space.
As the planet warms, increasing levels
of water vapour in the atmosphere caused by higher
evaporation levels form
more clouds and snow increasing the albedo
of the planet, reflecting heat back into space
more efficiently, thus working to regulate the temperature downward.
Remember that fresh
water freezes
more easily than the ocean's usual salt
water, so if downwelling fails locally, a puddle
of fresher
water may form from the rains or floods — and it will freeze
more easily, preventing the winds from doing their
evaporation job that might restart the downwelling.
But, if the atmosphere in the polar regions warms there will be
more evaporation and thus a postive feedback from greenhouse effect
of increased
water vapor.
There is growing evidence that this has already occurred31 through
more evaporation from the ocean, which increases
water vapor in the lower atmosphere32 and autumn cloud cover west and north
of Alaska.33
Climate models have long predicted that as global temperatures warm,
evaporation of surface
water will increase and
more moisture will be held in the atmosphere.
As
water warms
more evaporation occurs carrying energy higher in the troposphere where it can be lost
more easily — but there are considerations
of wind speed and atmospheric humidity.
«With global temperatures warmer now than they were at the beginning
of the last century, that means our temperatures are warmer too, which increases the rate
of evaporation and increases the demands on
water, increases the stress on the
water supply, and also leaves us
more susceptible to breaking the high - temperature record, which we've been doing lately,» Nielsen - Gammon said.
Because
of excessive
evaporation, tropical surface
water is
more saline.
i) That parcel
of air can be caused to expand relative to adjoining air parcels either by direct input
of more solar energy where insolation is uneven (as it always is) or indirectly by the injection
of potential energy in the form
of latent heat
of evaporation carried by
water vapour.
Hotter
waters lead to
more evaporation, which must eventually come down in the form
of precipitation.
Consequently, as air warms, for whatever reason,
more evaporation may take place and the concentration
of water vapor may increase.
More DLR increases
Evaporation and that increases the amount
of latent heat required and also increases upward Convection because
water vapour is lighter than air.
Evaporation of water takes out
of the local environment (but it stays in the system in latent form) 4 times
more energy than the sensible energy required to heat the same amount
of water to 100C.
* When it's warmer, the
evaporation of water speeds up, allowing the ground to heat up faster, which then evaporates
more water in a vicious cycle which continues until meaningful rain stops it.
