The darkness of land and water compared with the reflectiveness of snow and ice means that when the latter melt to reveal the former, the area exposed
absorbs more heat from the sun and reflects less of it back into space.
Darker than the snow and ice, this debris
absorbs more heat from the sun than its surroundings and causes the ice underneath to melt into cylindrical holes up to about a foot deep.
When ice melts it reveals darker Arctic Ocean water, which in turn
absorbs more heat from the sun, further heating the region.
Another positive feedback of global warming is the albedo effect: less white summer ice means more dark open water, which
absorbs more heat from the sun.
Conversely, when there is less Arctic sea ice, the ocean
absorbs more heat from the sun, adding to global warming.
That widespread melting leaves huge swaths of dark ocean water that
absorbs more heat from the sun than the white, reflective sea ice it replaces.
Its two faces differ strikingly in color, likely the result of thermal segregation: Over time, darker materials (like carbon) have
absorbed more heat from the sun, warming up and sending lighter, more volatile materials (like ice) to the colder hemisphere.
Dark - colored bowls will
absorb more heat from the sun than lighter ones.
The UP is not only
absorbing more heat from below, but we've added an IR emitter, CO2, to the UP layers, and so it can rid itself of more heat.»
The increasing greenhouse effect leads to a radiation imbalance:
we absorb more heat from the sun than we emit back into space.
Dark surfaces
absorb more heat from the sun.
Not only will melting Arctic sea ice raise global sea levels, it will also allow the earth to
absorb more heat from the sun because ice reflects the sun's rays while blue open water absorbs it.
Not exact matches
Note: If using a dark colored pan, reduce the oven temperature, stated in the recipe, by 25 degrees F. (This is because dark colored pans
absorb more of the energy coming
from the oven walls so they become hotter and transmit
heat faster than light colored pans.)
As a final note, if you cover the milk after
heating it and let it sit for 10 minutes, covered, it will
absorb more bouquet
from the vanilla bean.
As the climate changes, Southern Ocean upwelling may increase, which could accelerate ice shelf melting, release
more carbon into the atmosphere and limit the ocean's ability to
absorb heat and carbon dioxide
from the atmosphere.
For example, photonic crystals could funnel excess
heat from a power plant's generator and release it over a much smaller band of frequencies to drive engines — such as those in electric - powered cars that can
absorb energy only within a small range — much
more efficiently.
The whiter the ice, the
more reflective it is, and the less
heat it
absorbs from the sun.
The coat radiates
more heat to the cold sky than it
absorbs from its surroundings, the team reports, causing the temperature to drop below that of the surrounding air, while thick insulation reduces body

There are subtle effects such as the planet losing
more heat from the open sea than
from ice - covered region (some of this
heat is
absorbed by the atmosphere, but climates over ice - covered regions are of
more continental winter character: dry and cold).
Actually, though, most of the OLR originates
from below the tropopause (can get up around 18 km in the tropics, generally lower)-- with a majority of solar radiation
absorbed at the surface, a crude approximation can be made that the area emitting to space is less than 2 * (20/6371) * 100 % ~ = 0.628 %
more than the area
heated by the sun, so the OLR per unit area should be well within about 0.6 % of the value calculated without the Earth's curvature (I'm guessing it would actually be closer to if not less than 0.3 % different).
To summarize this concept, do you agree that when a layer's temperature is due to
heat absorbed by CO2 alone,
more CO2 will increase the temperature, whereas if the temperature includes
heating from something else as well,
more CO2 can help rid the layer of that extra
heat?
According to the scientist conducting the study, the soot — which comes
from the Chindia belt, as well as the Western world — and which is black,
absorbs heat from the sun
more readilly than white ice, thereby accelerating the warming and melting of the glaciers even
more than the Greenhouse effect.
Among the possible excuses offered by the UN's supposed experts for the lack of warming: «ash
from volcanoes,» a «decline in
heat from the sun,» or
more heat being «
absorbed by the deep oceans.»
In the Arctic, the tipping points identified in the new report, published on Friday, include: growth in vegetation on tundra, which replaces reflective snow and ice with darker vegetation, thus
absorbing more heat; higher releases of methane, a potent greenhouse gas,
from the tundra as it warms; shifts in snow distribution that warm the ocean, resulting in altered climate patterns as far away as Asia, where the monsoon could be effected; and the collapse of some key Arctic fisheries, with knock - on effects on ocean ecosystems around the globe.»
Note, for example, how the temperature trend in the first decade of the 21st century was generally flat because an upward push by anthropogenic forces was temporarily offset by a downward pull as solar activity decreased and the oceans
absorbed more heat than usual
from the atmosphere (sea water temperatures continued to rise).»
Loss of sea ice means
more heat from the sun is
absorbed by the ocean surface, adding to Arctic warming.
For example, the scientific explanation that temperatures have not risen since 2001 is because an «upward push by anthropogenic forces was temporarily offset by a downward pull as solar activity decreased and the oceans
absorbed more heat than usual
from the atmosphere (sea water temperatures continued to rise)».
Thanks to their large
heat capacity, the oceans
absorb warming caused by human activities, and
more than 90 % of the Earth's extra
heat from global warming is
absorbed by them.
More recently, scientists have been surprised to learn that black carbon — not only
from biomass fires but
from dirty diesel engines and other sources — is a far larger contributor to global warming than previously suspected: The dark particles
absorb and retain
heat close to the Earth's surface that might otherwise be reflected.
A leaked draft of the next major climate report
from the U.N. cites numerous causes to explain the slowdown in warming: greater - than - expected ash
from volcanoes, a decline in
heat from the sun,
more heat being
absorbed by the deep oceans, and so on.
According to the BBC, the draft IPCC report suggests that the oceans have been
absorbing more heat than expected, in effect insulating global surface temperatures
from greater change.
Some of the accumulated
heat will be released into the air above, the equilibrium has been disrupted, cooler surface, followed by
more heat absorbing from the source above, and so on, result surface temperature oscillation (the AMO).
But if a little
more energy is
absorbed, then CO2 is acting like a little black soot in the atmosphere and it will, in turn, radiate
more toward space as a black box would
from the added
heat and this might compensate for the change in albedo.
Bill Gray has a favorite diagram, taken
from a 1985 climate model, showing little nodules in the center with such labels as «thermal inertia» and «net energy balance» and «latent
heat flux» and «subsurface
heat storage» and «
absorbed heat radiation» and so on, and they are emitting arrows that curve and loop in all directions, bumping into yet
more jargon, like «soil moisture» and «surface roughness» and «vertical wind» and «meltwater» and «volcanoes.»
From latitudes 40 ° North or South to the poles, the earth increasingly ventilates
more heat than it
absorbs.

absorbs heat from the sun and then re-radiates it back into the atmosphere and to space.
To be energy or
more properly,
heat transferred, the one - way upwelling radiation
from the surface
absorbed by the air should be reduced by subtraction of the down - welling radiation of the air
absorbed by the surface Note that by subtraction of the (about 20 W / m ² in global average) flow surface to cosmos of both terms of GH, GH expression becomes GH = (radiation
from the surface
absorbed by the air) minus (outgoing longwave radiation
from the air) which has absolutely no physical sense!
CO2 and H2O vapour emit vastly
more heat than they
absorb because they are somewhere between +30 C and -55 C, depending on the height, and deep space is about -270 C, as always the
heat flows
from hot to cold, the bigger the temperature gradient the greater the
heat flow.
Since those 15 micron photons are impacting a surface that is already radiating away
from the hugely
more massive surface (speaking at molecular level) those photons will be
absorbed and radiated out again because the
heat store just below the molecular surface is at a higher energy potential.
If
more DLR
from more CO2 enters the skin layer, less
heat from absorbed SWR will need to flow upwards, and the ocean will get warmer.
This means the Earth
absorbed more energy
from solar radiation than it emitted as
heat back to space.
More likely the oceans on our 70 % water covered world, which
absorb heat energy
from the sun (for which we have some data), and geothermal energy (for which we have virtually no data), and release it over long periods of time by poorly understood mechanisms that are possibly the real driving force behind climate.
The gas which
absorbs the most
heat (infrared radiation) is the most effective greenhouse gas as in the atmosphere it would
absorb more infrared coming
from the Earth's surface.
While the location of the hottest place on Earth might shift
from year to year, the conditions that give rise to it remain the same: Dry, rocky and dark - colored lands are good at
absorbing heat, while lighter sand will tend to reflect
more sunlight.
Not to mention, why do skeptics continue to ignore, dismiss, or simply «argue with» by any means possible, the far
more important fact that most of the increased
absorbed heat energy is going into warming the oceans, not the atmosphere (thus keeping the ambient air temp rise
from registering as high as it otherwise would, and impacting FUTURE climate far
more).
(BTW, the skeptics like to game the Beer's Law thing — «existing CO2 already
absorbs all the IR
from the ground» — forgetting that
absorbed heat has to be re-emitted, and
more CO2 shifts up the equilibrium temperature.
