The ISCCP group produces an independent estimate of the albedo, from performing a full radiative flux calculation that takes into account observations of all radiative forcings and
produces top of the atmosphere, surface, and in - atmosphere fluxes (data, figure right).

A proton with energy
of 100 GeV interact at the
top of the
atmosphere and
produces a cascade
of secondary particles who ionize molecules when traveling through the air.
If the
atmosphere consisted
of Oxygen / Nitrogen only, its thermal conductivity would be very low, solar heating would be much the same, and the insulation effect (and the gravitational lapse rate) would
produce a substantial temperature differential from the surface to the
top of the
atmosphere without any radiative absorption.
Overlain on
top of this natural behavior is the small, and often shaky, observing systems, both
atmosphere and ocean where the shifting places and times and technologies must also
produce a change even if none actually occurred.
However, the observed energy imbalance at the
top -
of -
atmosphere for this recent decade indicates that a net energy flux into the climate system
of about 1 W m − 2 (refs 2, 3) should be
producing warming somewhere in the system4, 5.
Heat picked up at the surface is thus rapidly vertically mixed and transported by all three mechanisms — conduction, convection and radiation — acting at different length scales and with considerable and non-ignorable chaotic and self - organized emergent mesoscale structure — to
produce an
atmosphere that, as you note, ends up somewhere between the DALR and isothermal most
of the time, although inversions (warmer on
top) or with a gradient even larger than the DALR happen all the time, and are unstable or transiently metastable states with some lifetime and break apart and perhaps reform somewhere else as the conditions that favor them recur.
The first is the original «invisible something barrier» at the
top of the
atmosphere, TOA, like the glass
of a greenhouse, preventing the longwave infrared from the Sun from entering, but allowing the mainly visible light to reach the surface and directly heat it and the second is that the Sun
produces insignificant amounts
of longwave infrared and none
of this gets through TOA.
However, most
of the methane
produced from dissociating marine hydrates will be consumed by anaerobic processes in the
top few metres
of sulphate - rich near - sea - floor sediments and all
of the rest will be dissolved and oxidized in sea water and will not be released to the
atmosphere as methane, although the dissolved CO2 will equilibrate with
atmosphere after a few centuries.
