And while there's some (very slow) escape of gas, that depends on the molecular weight of the gas. So while hydrogen & helium escape relatively easy, the principle GHG, carbon dioxide, is heavier than either atmospheric oxygen & nitrogen. So if anything, escape into space would result in a HIGHER GHG concentration. – jamesqf.
WebHelium constitutes about 23 percent of the mass of the universe and is thus second in abundance to hydrogen in the cosmos. Helium is concentrated in stars, where it is synthesized from hydrogen by nuclear fusion. Although helium occurs in Earth’s atmosphere iron, and mineral springs, great volumes of helium are found as a …
WebIn order to escape Earth’s gravity, an object near the top of the atmosphere (at an altitude of 100 km) must travel away from Earth at 11.1 km/s. This speed is called the escape velocity.
