Losses from surface melting, water runoff, the breakup of glaciers into the ocean (calving), and the transformation of solid
ice into water vapor (sublimation) exceed any gains through snowfall.2, 3,4,5 The Greenland ice sheet loses most of its mass on the perimeter, through a dozen fast - moving glaciers, including Helheim.5, 6
«The product is first frozen, then the sublimation process converts
the ice into water vapor, removing most of the moisture from the product while keeping the nutritional value virtually the same,» Milchman says, adding that this is a fairly recent innovation in food preservation, one that offers several benefits over other methods, such as using artificial preservatives or dehydration, which can affect the appearance and composition of products.
Instead, they shrink when sunlight hits the surface and transforms
ice into water vapor, a process called sublimation.

When an icy impact occurred, the impactor's kinetic energy became heat energy, instantly melted some
ice, gouged out a crater, and kicked up
into Mars» thin atmosphere large amounts of debris mixed with
water (liquid,
ice crystals, and
vapor)-- and complex organic molecules that obviously came recently from life.127 Then, the dirt and salt -
water mixture settled back to the surface in vast layers of thin sheets — strata — especially around the crater.
As this
water moves through rocks, it dissolves salt compounds and pushes through fractures in the overlying
ice to form reservoirs closer the moon's surface, where it is expelled
into space when the outermost layer of the crust cracks open and the resulting depressurization of these reservoirs causes
water vapor and
ice particles to shoot out in the observed plumes.
Then an 18 - hour freeze - drying process gently converts the
water frozen in the ingredients
into ice vapor, without creating any liquid.
Freeze drying converts solid
water (
ice) directly
into water vapor, skipping the liquid phase completely (this is called sublimation).
In addition, since the global surface temperature records are a measure that responds to albedo changes (volcanic aerosols, cloud cover, land use, snow and
ice cover) solar output, and differences in partition of various forcings
into the oceans / atmosphere / land / cryosphere, teasing out just the effect of CO2 +
water vapor over the short term is difficult to impossible.
For any given temperature, it tells you how high you can make the partial pressure of
water vapor before the
vapor starts to condense
into liquid or
ice.
The loss of
ice cover not only means that more open
water will be around to directly warm the air
into the Arctic night, but that more
water vapor will be around to hold heat in.
Once an
ice crystal has formed, it absorbs and freezes additional
water vapor from the surrounding air, growing
into a snow crystal or snow pellet, which then falls to Earth.
It originates in clouds when temperatures are below the freezing point (0 degrees Celsius, or 32 degrees Fahrenheit), when
water vapor in the atmosphere condenses directly
into ice without going through the liquid stage.
AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take
water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on land and oceans as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar
ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back
into space, changing the moment of inertia of the earth by removing
water mass from equatorial latitudes and transporting this
water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..
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).
The Greenland

Ice sheets grow through snowfall, and shrink through surface melting,
water runoff, breakup
into the ocean (calving), and direct transformation
into water vapor (sublimation).
This means that the more sea
ice there is and the smaller the area of open
water, the less
water vapor is lifted
into the atmosphere.
As the Arctic sea
ice melts, the
water vapor delivered
into the the atmosphere increases in the polar region, and so does the snowfall, so that the whole thing starts over again.
However, as the
water vapor rises the lapse rate means that the volume of air cools and eventually the
water vapor condenses
into water droplets and then
into ice latent heat is given off to the surrounding air at each of these phase changes, with two effects.
As this process accelerates, the
ice caps melt, releasing more
water vapor into the atmosphere via evaporation, further compounding the effect caused by unregulated carbon dioxide emissions.
In light of trends showing a likely 3 °C or more global temperature rise by the end of this century (a figure that could become much higher if all feedback processes, such as changes of sea
ice and
water vapor, are taken
into account) that could result in sea level rises ranging from 20 to 59 cm (again a conservative estimation), Hansen believes it is critical for scientists in the field to speak out about the consequences and rebuke the spin offered by pundits who «have denigrated suggestions that business - as - usual greenhouse gas emissions may cause a sea level rise of the order of meters.»
Water vapor, unconstrained by
ice, will pour
into the Arctic atmosphere, augmenting the greenhouse effect and feeding storms quite different than those now experienced.
