Because Mars has a surface gravitational force 4/10ths that of Earth, it's atmosphere is subject
to what planetary scientists call atmosperic "sputtering":
That is?...The loss of gaseous molecules and atoms (especially, light ones) that escape from the planet's upper atmosphere due to their high
molecular/atomic velocities (the kinetic energy obtained by absorbing solar radiation).
OK! Presently, the average martian daytime surface temperatures would be
close to 200 Kelvin...
Suppose you create a "greenhouse effect" on Mars, what then?
You raise the average daytime surface
tempratures to MAYBE 280 Kelvin,
to be arbitrary (273 Kelvin: frezing point of H20 at STP).
The difference between 280 Kelvin
and 200 Kelvin, spelled out in the
amount of kinetic energy gained
and absorbed by the overlaying layers of atmospheric gases is (280/200)^1/2...That would mean
an increase in martian atmospheric "sputtering" by [roughly] 20 percent.

This is something I do remember from physics.
