WEB Jan 26, 2017  · In the big picture, 400 ppm is a low-to-middling concentration of CO2 for the planet Earth. Some 500 million years ago, when the number of living things in the oceans exploded and creatures first stepped on land, the ancient atmosphere happened to be rich with about 7,000 ppm of carbon dioxide. WEB For example, an XCO 2 concentration of 400 ppm means that the atmosphere above a certain location contains on average 400 CO 2 molecules in every one million air molecules (excluding water vapour).
