It means, in essence, that outgoing long wave radiation, which would otherwise escape back into Space, is absorbed by atmospheric CO2 and converted into vibrational bending and stretching of the bonds in the molecules, this results in thermal energy. The main absorption band for CO2 is centred around 15μm, which is tapped out, or saturated, at the centre so the heating occurs at the edges, or wings, of the graph. The CO2 absorption spectrum shows it absorbs LWIR at three different narrow wave lengths, sometimes called finger frequencies. Two of those wave lengths happen at temperatures too hot to exist in the atmosphere, the remaining wave length is 15um.
Absorption of surface IR by CO2 does not warm the Earth. It is also not a force. There is no forcing. The surface is COOLED by emitting IR light. It's just another way for the surface to cool by heating the atmosphere.
Please note that radiative forcing is a logarithmic function, meaning that quadrupling concentration only results in a doubling in forcing. This means that the forcing effect attenuates with higher concentrations. Think of it as a greenhouse where the windows are painted black, the first coat shuts out most of the light whilst subsequent coats have less and less of an effect.
There is no 'forcing'. CO2 is not a force.
This is well known amongst climate scientists
Climate 'scientists' deny science and mathematics. Science does not use consensus. Science is never 'settled'. There are no proofs in science. It is an open functional system. No theory is ever proven. No theory is possible to exist at all based on a void argument fallacy. Define 'climate change'.
and is not in the least controversial.
Then why is there so much controversy?
In Thermodynamics, Temperature is the average kinetic energy of the particles in a body (solid or gas). A fact that our fine feathered friends seem incapable of understanding.
Lie. I accept that definition of temperature. Always have. Irrelevance fallacy.
The temperature increase for an initial doubling from 280ppm, the start of the Industrial Revolution, to 560ppm is around 1.2C.
It is not possible to measure the temperature of the Earth. It is not possible to measure the global concentration of CO2 in the atmosphere. You don't have enough instrumentation.
Math error: Failure to provide raw unbiased dataset. Failure to select by randN. Failure to normalize by paired randR. Failure to declare variance. Failure to calculate margin of error.
Argument from randU fallacy.
That is pretty much accepted by all climate scientists,
Like I said. Climate 'scientists' deny math, just as you do.
the real argument is centred around feedbacks.
From The Manual:
Feedback: noun
A feedback is a specific type of forcing employed by Climate that overcomes the physical limitations of the 1st and 2nd Laws of Thermodynamics by creating additional usable energy. Feedbacks come in various subcategories, e.g. thermal, climate, hydrostatic, radiative, etc.. This falls under
Settled Science.
They will also say that increased temperatures results in more clouds and that is not modelled by the current crop of CMIP5 climate models.
By 'models', you mean computer programs. Models don't predict anything.
Computer programs only spit out the numbers they are told to spit out. A model in a computer program is the 'noun' the program works on 'the verb'. Models themselves are randU. They simply come out of someones head. The programs that run on them also simply come out of someone's head. Neither are capable of prediction. They are random numbers of type randU.
A randU is the 'predictable' random number. They all come out of someones head. When that someone tries to use them as data or as a predicate, that is a fallacy, known as an argument from randU fallacy.
Models are not a proof. They are worth nothing more than Holy Entrails.
