One classical thermal escape mechanism is Jeans escape. In a quantity of gas, the average velocity of a molecule is determined by temperature, but the velocity of individual molecules change as they collide with one another, gaining and losing kinetic energy. The variation in kinetic energy among the molecules is described by the Maxwell distribution. The kinetic energy and mass of a molecule determine its velocity by .
The more massive the molecule of a gas is, the lower the average velocity of molecules of that gas at a given temperature, and the less likely it is that any of them reach escape velocity.
This is why hydrogen escapes from an atmosphere more easily than does carbon dioxide. Also, if the planet has a higher mass, the escape velocity is greater, and fewer particles will escape. This is why the gas giant planets still retain significant amounts of hydrogen and helium, which have largely escaped from Earth's atmosphere. The distance a planet orbits from a star also plays a part; a close planet has a hotter atmosphere, with a range of velocities shifted into the higher end of the distribution, hence, a greater likelihood of escape. A distant body has a cooler atmosphere, with a range of lower velocities, and less chance of escape. This helps Titan, which is small compared to Earth but further from the Sun, retain its atmosphere.

Greenhouse gases trap and intensify the sun's heat -- much the way the glass of a greenhouse works -- preventing that heat from escaping into the atmosphere.
The 2015Aliso Canyon gas leak, which took four months to control, released more than 120,000 metric tons of methane and other gases into the atmosphere over communities in the San Fernando Valley.

Pulling carbon dioxide directly from the air is a way to clean up historic emissions that have already escaped into the atmosphere, meaning it can potentially help slow and even reverse climate change.
