do simple example - double P
and double double epsilon
what value do you have to change T by for the result to balance?
HINT = T doesn't have to change at all in the example.

Increasing the concentration of CO
2 from 0.028% to 0.038% does not double epsilon for the atmosphere. In fact it makes nearly no difference at all in epsilon for the atmosphere.
