The AGW hypothesis essentially is an extraordinary claim that
adding radiative gases to the atmosphere will reduce its radiative cooling ability.
--
adding radiative gases to the atmosphere will not reduce its radiative cooling ability.
What the foundation claim of AGW boils down to — «
Adding radiative gases to the atmosphere will reduce the atmospheres radiative cooling ability.»
For an atmosphere with a pressure gradient in which the gases are free to move,
adding radiative gases to the atmosphere will only speed up convective circulation and tropospheric cooling.
Adding radiative gases to the atmosphere will not reduce the atmospheres radiative cooling ability.
Not exact matches
The elevation of the atmospheric temperature is due to a shift in the
radiative equilibrium, i.e. more back radiation absorbed by
added gases, selective to IR radiation.
Where you then have a talik, from this combination of geological and
radiative forces, and then there is plenty of free
gas underneath that can migrate out easily through pathways once there are such tears, and then you
add on top of all that that it is a seismically active zone, one can easily see how global warming could greatly amplify the effects of an earthquake at that fault zone.
Yup, but by definition as we
add greenhouse
gasses, we depart from equilibrium, so the processes do not cancel and there is a net flow of energy from
radiative to kinetic.
Add to this that our understanding of the
radiative effects of GH
gases is based on masses of detailed data and is applied in many fields - Astronomy, Defence, Satellite observations of all types, Meteorology, even designing Micro-wave ovens - oh, and Climate Science.
Scientists keep track of natural forcings, but the observed warming of the planet over the second half of the 20th century can only be explained by
adding in anthropogenic
radiative forcings, namely increases in greenhouse
gases such as carbon dioxide.
Add CO2 to a
gas without changing its temperature, and watch its
radiative emission increasing in the CO2 bands.
However, it is much easier to figure out what happens when you
add more
radiative gases to an atmosphere that already has them: And, the answer is that it increases the IR opacity of the atmosphere, which increases the altitude of the effective radiating level and hence means the emission is occurring from a lower - temperature layer, leading to a reduction of emission that is eventually remedied by the atmosphere heating up so that
radiative balance at the top - of - the - atmosphere is restored.
Houghton (2004: 259) explains that when converting from carbon dioxide only concentrations to carbon dioxide equivalent concentrations, the amount that needs to be
added varies with different concentrations of greenhouse
gases as the relationship between
radiative forcing and concentration is non-linear.
The index is defined as the cumulative
radiative forcing between the present
add some chosen time horizon caused by a unit mass of
gas emitted now, expressed relative to that for some reference
gas (here CO2 is used).
Adding insult to injury now at this point (the sadist in me I guess) the ballyhooed insulating effect of greenhouse
gases now serves to insulate the surface against the LWIR eminating from the newly condensed vapors and makes the path of least resistance
radiative transfer out to the cold dark cosmic void.
