Re: Not even miniscule . . .
<The loss is miniscule compared to the immense ocean of air covering our world, but is significant in terms of what drives space weather around our world.
The above is from the link you posted (Science@NASA is an excellent source!). The impact pressure that releases the gasses from the Earth's atmosphere, though, is very tiny, equivalent to approx. 10 nanopascals (0.00000000000009872 atmospheres), or roughly zero, and the trivial amount of escaping gasses are not worth the worry. These are being replaced daily through the oceans, life (plant & animal) and geothermal activity. Solar CME's have been impacting the Earth's magnetosphere since before life existed.
