Aha; there you go making assumptions.

Try to remember in future that when dealing with your superiors it is
always a good idea to ask questions.

There will be a very small amount of sunlight reflected off the moon
that then reflects off the Earth.

Far from being peantic you are incorrect. The sun shine on Japan for
example shines "at night" in New York. Then there is the small matter
of the various twilights. At the moment too, the sun is still shining
all day and night in the north polar regions.

Here is the pedantic bit:

The sunlight I was referring to is insolation. The point is that the
heat balance is the zero not the actual light itself. To be more
pedantic one must also analyse the meaning of the word "light". In
it's broadest spectrum one may describe the light in question as heat
from the sun. In my opinion there is no difference other that category
of frequency in any of the heat radiated from the sun.

If this light from the sun does not leave the earth both night and day
then one might allow there is something to be said for global warming.

There isn't.
