I can't force you to think about this, but please note, in traditional science heat and light from the Sun are two entirely distinct from each other categories and not interchangeable, so, when «heat and light from the Sun» are mentioned together like this, by «heat» is meant the Sun's thermal energy on the move to us, radiant heat, the electromagnetic waves of thermal infrared aka longwave infrared, and by «light» is meant visible.

>> >> >> >> >> >> >> > When RMB says «heat» he is talking about infrared radiation and therefore he is correct.

My argument here is about the fake fisics in the claim «shortwave in longwave out», the standard AGW model which says no Thermal Infrared direct from the Sun has any part in heating land and ocean and which has instead substituted shortwave from the Sun claiming shortwave does this heating when it is absorbed, mainly visible as I've given examples — I'm asking you, all, to prove this claim.

Except now we don't call it «dark light», that was what Herschel called it when he first discovered heat from the Sun was invisible, but we call it thermal infrared because our measuring techniques are much improved since Herschel's day and we can now accurately say that the shortwave infrared is not thermal, it is not hot.

The molecule will first use the heat energy in expansion and on cooling will again condense and sink because heavier, and it will cool when its heat expanded volume flows to colder air which absorbs the heat, the internal kinetic energy of vibration, which if strong enough will pass that heat to another colder (which is why visible light is not a thermal energy, it is not powerful enough to move a molecule of matter into vibration, it takes the bigger heat wave, longwave infrared, aka thermal infrared called that because it is the wavelength of heat)-- that is how convective heating warms the fluid gas air in a room, by circulation, in the rise and fall of molecules as they expand and condense, not by heat energy propelling molecules to hit other molecules..
