did you mean
re-emits the energy as thermal heat (short wave radiation)?
Yes, my bad.
ok , the IR photons were absorbed by the atoms in the
CO2 molecules.
when the ground heats up through IR , Visible , UV radiation
and then later emits heat (thermal heat) , do you think
that the ground would cool by the amount of heat that the
ground emits?
Yes the ground cools as it emits the heat. Of course during the day there is more incoming UV and visible radiation than there is IR radiation. So during the day the ground warms up. At night when the incoming radiation goes away the ground cools. Of course then some of the IR radiation is trapped by the CO2 (and other greenhouse gases) so that it warms the air, which then transfers some of the heat back into the ground.
The rest of your message seems to still be ignoring the fact that there is much more UV and visible radiation coming in from the Sun during the day than there is IR. So the reduction of energy that doesn't reach the ground due to IR absorption is a very small fraction of the total energy that does reach the ground in the other wavelengths.
