Atmospheric Oxygen Levels Fall As Carbon Dioxide Rises Published: Dec 14, 2007 The ongoing study [Scripps Institute], which accumulated and interpreted data from NOAA monitoring stations all over the world, has been running from 1989 to the present. Since the beginning of the industrial revolution we have removed .095% of the oxygen in our atmosphere. True, that is only a tenth of one percent of the total supply, but oxygen makes up only 20% of the atmosphere. I looked up safety rules regarding oxygen concentrations and according to OSHA rules on atmospheres in closed environments, "if the oxygen level in such an environment falls below 19.5% it is oxygen deficient, putting occupants of the confined space at risk of losing consciousness and death." ... The sequestration of carbon dioxide by pumping it under the ground would only dispose of the carbon dioxide with unknown consequences, but would do nothing to stop the depletion of oxygen from the atmosphere. Dr. Keeling agreed that carbon sequestration would do nothing to stop oxygen depletion but reassured me that "... the O2 loss is too small to be much of a concern." blogcritics.org/scitech/article/atmospheric-oxygen-levels-fall-as-carbon/#ixzz0osSsSfH0

Stunned scientists warn world could run out of breathable air Professor Ralph Keeling of Scripps Institute is worried. In fact, he's very worried. According to the data Keeling has meticulously collected since 1989 the world is running out of breathable air—and the rate that it's losing oxygen is now on the verge of accelerating. Monitoring oxygen levels around the world is Keeling's job. He's very good at his job. And the data confirms that Earth's oxygen supply is dwindling. www.helium.com/items/1965918-keeling-curve-co2-and-loss-of-atmospheric-oxygen

Why were prehistoric insects so huge? - Sep 03, 2012 When the giant insects were around – 350-50 million years ago – during Earth’s Carboniferous and early Permian period – our planet was warmer, moister, and contained more oxygen. Back then, the atmosphere contained over 30 percent oxygen, compared to today’s air, which is made up of 21 percent oxygen earthsky.org/earth/why-were-prehistoric-insects-so-hugeThe color has some apocalypse believers suggesting that OC Fisher is an early sign of the end of the world, but Texas Parks and Wildlife Inland Fisheries officials say the bloody look is the result of Chromatiaceae bacteria, which thrive in oxygen-deprived water. www.livescience.com/15346-texas-lake-blood-red.html
