Ever wondered about running out of oxygen? I have.
Whether diving in the deep blue, or scaling upwards to the highest elevations you may have felt the effects of diminishing levels of oxygen supply.
Now some interesting information comes out of the University of California, Script's Institute of Oceanography and the son of the famous scientist, Charles David Keeling, who developed the "Keeling Curve" which depicts the rise of carbon dioxide in the atmosphere.
According to studies conducted by Ralph Keeling, an atmospheric geochemist also from Scripps, has shown that there is a direct relationship between levels of oxygen and carbon dioxide in our atmosphere.
As carbon dioxide levels increase oxygen decreases. Fear not though as Ralph's numbers show that if current trends continue, we will still have about 50,000 years breathing time left!
However, this new information does show that there is more to global warming than just a simple rise in levels of carbon dioxide. The general assumption that the ocean and plants would simply continue to absorb CO2 and replace it with oxygen is no longer something to take for granted.
