The approximate ratio of oxygen (O2) to carbon dioxide (CO2) in Earth's atmosphere is 525:1 by volume, or 20.95% O2 to 0.04% CO2. This means for every molecule of CO2, there are roughly 525 molecules of O2. By mole fraction, the atmosphere is approximately 78.08% nitrogen, 20.95% oxygen, and 0.04% carbon dioxide.JohnnyYou » 09 Jul 2025, 5:26 pm » wrote: ↑ Oxygen is 21000 ppm of the atmosphere. Varying that has a lot of stuff to consider behind it.
I remember being fully taught the coal and oil would be gone by 2025 in elementary school. No one foresaw fracking the gas out of the underworld. The graph above (if you can read one) is a pretty strong argument for anthopogenic sources.
And we haven't even touched the methane cycle yet. Farts Count!
Are you catching on yet?
Or are you always this slow .....?????
