Greenhouse effect affected by Earths Gravity?

Click For Summary
SUMMARY

The discussion centers on the relationship between Earth's gravity and the greenhouse effect, specifically how gravity influences atmospheric retention of gases. It establishes that while gravity holds the atmosphere close to Earth, certain molecules can escape if they reach escape velocity, which occurs daily. The participant questions whether the increased kinetic energy of greenhouse gases, due to heat radiation from Earth, leads to a measurable loss of these gases from the atmosphere, potentially counteracting the greenhouse effect. The conclusion is that while the escape of molecules may be minuscule, it is a valid consideration in understanding atmospheric dynamics.

Hey, so I was thinking how the atmosphere is held close to Earth due to gravity and realized that if certain molecules have a certain amount of kinetic energy, they are bound to leave the atmosphere correct? I mean there is an escape velocity that these molecules must need and I'm sure molecules escape the atmosphere daily.

So my question is, is there some kind of counter acting force that occurs to the greenhouse effect due to gravity? From my understanding, the greenhouse effect occurs when heat radiation from the Earth hits green house gases effectively heating up the earth. But what I mean by counter acting force is that since these gases heat up, they seem to have a higher kinetic energy, as they bounce through different molecules, eventually molecules on the outer atmosphere are going to have more kinetic energy due to the transfer of kinetic energy from the collisions and the continuous heat radiation from Earth attributing to this. So these molecules with higher kinetic energy are going to leave the atmosphere, thus reducing the average kinetic energy of the Earth's atmosphere correct? So isn't there some value of molecules that leave the atmosphere due to the increased kinetic energy that lowers the average temperature of the atmosphere? I'm sure this number is minuscule, but it surely must exist right?
