All CO2 molecules in the atmosphere are warmed to
local air temperature by collision induced conduction to above this temperature.
When this water condenses this latert heat is given up so if this happens near the surface
then local air temperatures will increase slightly.
It seems that CO2 can absorb all it meets (within its limited spectra) but can not emit much
because local air temperatures are far, far too low for the CO2 molecule to reach the required kinetic energy level to emit a photon.
Observations from the National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellites (GOES) measure
the local air temperature in kelvins (degrees Kelvin) at different layers of the atmosphere.
The aspect of the paper that has attracted the most attention is the claim that the retreat of the Kilimanjaro summit glaciers can be explained by precipitation reduction, without any compelling need to invoke a warming trend in
local air temperature.
Even in winter, rooftop temperatures can be tens of degrees warmer than
local air temperatures.
Craig: One way that the ocean can transfer heat to the atmosphere even though
the local air temperature is warmer than the water temperature is through evaporation.
Thermostatic radiator valves (TRVs) detect
the local air temperature in the room and switch the radiator off if necessary.
