of time — from the celestial

of colonial forces or to deny the
simple truth
of human mortality.

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.
