The latest scientific scare is upon us: Oxygen Depletion. Using
computer models, scientists have determined that
oxygen-depleted zones are expanding. They conclude that it might be due to global warming.
Obviously, if it might be due to global warming, then, logically, it might not be due to global warming.
If they are using computer models to predict the expanding zones, their computer models are just that: computer models. Nothing more. The computer model is only as good as the information fed into it, the program that is written for it and the software designer's parameters.
But because they are claiming that it might be due to global warming, they should be able to get more financing to get more data and make more
observations.
One thing you might note, as with all scare-mongering, is that there are no numbers. How much less oxygen is there in the oxygen-depleted zones? I suspect because the numbers are so small, that they may be insignificant. Now, my understanding of the measurement of a gas, such as air, is that there are a number of factors necessary in order to determine the percentage of gas. One of the factors is temperature and another is barometric pressure. What this means is that if you have a higher or lower temperature at sea level, the amount of oxygen will vary. If you take measurements at different air pressures, the amount will vary.
I'm suspecting that they made a formula to "correct" the readings they were getting at various barometric pressures and temperatures, and then extrapolated to "prove" that the oxygen depletion was expanding.
As P.T. Barnum said, "There's a sucker born every minute, and two to take him."
