It floats to the top of the atmosphere and is blown out into space by the solar wind. eleven chicagoAtmospheric escape of hydrogen on Earth is due to charge exchange escape (~60–90%), Jeans escape (~10–40%), and polar wind escape (~10–15%), currently losing about 3 kg/s of hydrogen. The Earth additionally loses approximately 50 g/s of helium primarily through polar wind escape. Escape of other atmospheric constituents is much smaller.

WebApr 12, 2024 · 5. 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.
