If so, I don't understand. Black absorbs the sun's rays rather than

Look up how a greenhouse works. It has to do with trapping infrared light
between the earth and the plastic which rapidly heats the air by radiative
heating.
Clear plastic allows light through which can be reflected as infrared.
Black plastic does not.

Strangely, I have pepper mint growing under the clear plastic.
Everything else is dead.

In response to Perse

kzin's response is as good as any. I don't understand the thermodynamics
of the system but I can understand the empirical results.

Old saying, "logic is only as good as its' premise".
