Earth's Oxygen Levels Are Declining And Scientists Don't Know Why

  1. let's figure out that missing oxygen problem, shall we, Jenna?

    oxygen used to be about 21% of the atmosphere... that's 210,000 parts per million, right? so a 0.7% decrease would take out 1470 molecules of oxygen per million molecules of air...

    over the industrial era, atmospheric CO2 went from 280 parts per million to 410 parts per million. so that accounts for 130 parts per million of the missing oxygen. however, only 10% of the CO2 we create from oxygen goes into the atmosphere; the rest of it goes into the oceans. so the 90% of our CO2 that's in the oceans accounts for another 1170 parts per million of the missing oxygen...that means there's really only 170 molecules of oxygen per million molecules of air that are unaccounted for...we'll let the confused scientists find the rest of it, ok?
