The oxygen quantity is dropping, as expected (it shows the CO2 increase is from combustion, not volcanic outgassing). The 'source' link has lots of primary references if you want. But the oxygen decrease is small in absolute terms, so suffocation is certainly not on the cards!

Time to lock it folks.
