Trees perform three major climate functions: They
absorb carbon, which they pull from the
atmosphere, creating a cooling effect; their dark green leaves
absorb light from the sun,
heating Earth's surface; and they draw water from the soil, which evaporates into the
atmosphere, creating low clouds that reflect the sun's hot rays (a mechanism known as evotranspiration that also leads to cooling).
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.

The team calculated that those hydrocarbon clumps could

heat.
The formation of a stratosphere layer in a planet's

heat into our
atmosphere at a mind - boggling rate of 175 quadrillion watts, the air near the equator
absorbs more energy than the air near the poles.

It seems that the oceans have
absorbed much
heat over the summer but have relased it into the
atmosphere which has caused the ocean to freeze quickly and oddly even though the
atmosphere is warmer than usual.
Naturally this article fails to mention that since the hydrosphere is 271 times as massive as the
atmosphere, if oceans are
absorbing the
heat they are likely to moderate AGW into a nonproblem, as the average ocean temperature has only changed by.1 degrees in 50 years, an amount that is probably smaller than measurement error.
greenhouse gas A gas in Earth's
atmosphere that
absorbs and then re-radiates
heat from the Earth and thereby raises global average temperatures.
The formation of a stratosphere layer in a planet's
atmosphere is attributed to «sunscreen» - like molecules, which
absorb ultraviolet (UV) and visible radiation coming from the star and then release that energy as
heat.
Figure 1 shows the
heat capacity of the land and
atmosphere are small compared to the ocean (the tiny brown sliver of «land +
atmosphere» also includes the
heat absorbed to melt ice).
The amounts that are in Pluto's
atmosphere are enough to
absorb infrared radiation (
heat) from the sun and warm the upper
atmosphere.
Gases that trap
heat in the
atmosphere are called greenhouse gases, in large part because they
absorb certain wavelengths of energy emitted by the Earth.
The ocean stores much of the
heat absorbed by the excess greenhouse gases in the
atmosphere, so it could be beginning of that
heat being unleashed back into the
atmosphere.
The reason for this disparity in figures is that previous models did not take into account the gradual reduction in the ocean's ability to
absorb heat from the
atmosphere, particularly at the poles.
Isn't one important feature of cooling the stratosphere by emitting
heat absorbed by ozone from incoming shortwave radiation, that this cooling has little effect on lower parts of the

Now, if we want to move further into the future, we have to include the oceans, which are also
absorbing heat from the
atmosphere — so if we warm the
atmosphere, we warm the oceans (as well as the land surface).
If one could see the IR light, an opaque
atmosphere would make the pattern of emitted IR diffuse since only the IR from the upper levels of the
atmosphere escape to space after it has been
absorbed and re-emitted by the greenhouse gases (this of course depends on the wavelength of the IR and the absorption spectrum, but we can use this assumption for
heat loss integrated over the whole IR spectrum).
The paper illustrates the importance of remembering that the

These wildfires release soot into the
atmosphere, which accelerates the rate of melting of glaciers, snow and ice it lands upon, which can lead to less reflectivity, meaning more of the sun's

absorbed, leading to more global warming, which leads to even more wildfires, not to mention greater sea level rise, which is already threatening coastal areas around the world.
Hypothesis A — Because the atmospheric radiation is completely
absorbed in the first few microns it will cause evaporation of the surface layer, which takes away the energy from the back radiation as latent
heat into the
atmosphere.
Since anthropogenic emitted CO2 comes out of a power plant stacks / vehicle exhausts at an elevated temperature (due to the trivial manmade waste
heat energy), and then cools down to near equilibrium with the rest of the
atmosphere, why would this new CO2 then
absorb more energy and heatup again?
CO2 (and some other gases) in the
atmosphere are however more opaque to LWIR; they
absorb that a chunk of that outgoing radiation and re-radiate it in all directions — so that a fraction less than half is re-radiated downwards; which has the effect of slowing the transfer of
heat (by radiation) out of the
atmosphere.
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).
With some LW
absorbing optical thickness, the
atmosphere can emit radiation to space, so some
heat will flow into the
atmosphere from where solar
heating occurs to get to space.
The IPCC scientists agree that much of the
heat that humans have put into the
atmosphere since the 1970s through greenhouse gas emissions probably has been
absorbed by the ocean.
1) Greenhouse gasses
absorb infrared radiation in the
atmosphere and re-emit much of it back toward the surface, thus warming the planet (less
heat escapes; Fourier, 1824).
PS when molecular collisions are frequent relative to photon emissions and absorptions (as is generally the case in most of the mass of the
atmosphere), the radiant
heat absorbed by any population of molecules is transfered to the
heat of the whole population within some volume, and molecules that emit photons can then gain energy from other molecules.
With zero LW
absorbing optical thickness within the
atmosphere, the
heat must get to surface (if not already there) before escaping to space.
