A real greenhouse primarily restricts heat escape by preventing convection while the «greenhouse effect» heats the Earth because «greenhouse gases» (GHG) absorb
outgoing radiative energy and re-emit some of it back towards Earth.
I get upset when I see «The greenhouse effect heats the earth because greenhouse gases absorb
outgoing radiative energy and re-emit some of it back towards earth.»
The greenhouse effect heats the earth because greenhouse gases absorb
outgoing radiative energy and re-emit some of it back towards earth.
So it seems to me that the simple way of communicating a complex problem has led to several fallacies becoming fixed in the discussions of the real problem; (1) the Earth is a black body, (2) with no materials either surrounding the systems or in the systems, (3) in radiative energy transport equilibrium, (4) response is chaotic solely based on extremely rough appeal to temporal - based chaotic response, (5) but at the same time exhibits trends, (6) but at the same time averages of chaotic response are not chaotic, (7) the mathematical model is a boundary value problem yet it is solved in the time domain, (8) absolutely all that matters is the incoming radiative energy at the TOA and
the outgoing radiative energy at the Earth's surface, (9) all the physical phenomena and processes that are occurring between the TOA and the surface along with all the materials within the subsystems can be ignored, (10) including all other activities of human kind save for our contributions of CO2 to the atmosphere, (11) neglecting to mention that if these were true there would be no problem yet we continue to expend time and money working on the problem.
As a second - ascent giant brightens, the star's outer gas layers become unstable, and it may begin to «valve»
its outgoing radiative energy by pulsating which also changes its brightness.

Earth's
energy balance In response to a positive
radiative forcing F (see Appendix A), such as characterizes the present - day anthropogenic perturbation (Forsteret al., 2007), the planet must increase its net
energy loss to space in order to re-establish
energy balance (with net
energy loss being the difference between the
outgoing long - wave (LW) radiation and net incoming shortwave (SW) radiation at the top - of - atmosphere (TOA)-RRB-.
«
Radiative forcing is a measure of the influence a factor has in altering the balance of incoming and
outgoing energy in the Earth - atmosphere system and is an index of the importance of the factor as a potential climate change mechanism.
«Effect» is here defined in terms of
radiative forcing (RF), which is (loosely) the change in the amount of incoming (to Earth) versus
outgoing (to space) radiation /
energy, measured in watts per square metre (w / m2).
They also performed a number of
radiative computations to examine the spectral features of the incoming and
outgoing radiation and determined the role of clouds and various greenhouse gases in the overall
radiative energy flows.
