400 PPM: Carbon Dioxide in the Atmosphere Reaches Prehistoric LevelsDavid Biello
So, the reason we have large quantities of water vapour in the atmosphere in the first place is due to this effective temperature independence of carbon dioxide. Thus, throughout the various ice ages and interglacial periods the Earth has gone through, it has largely ...

The number ofparts per million(ppm) tells you how much of a specific substance is in a larger mixture. In other words, it's a measure ofconcentrationand is widely-used in fields like chemistry and even as a measurement for things like the amount of carbon dioxide in the atmosphere. Under...
The daily mean concentration of carbon dioxide (CO) in the atmosphere at Mauna Loa, Hawaii, hit 400.03 parts per million (ppm) on 9 May, marking the first time the concentration there has topped 400 ppm since measurements began at Mauna Loa in 1958, the U.S. National Oceanic and Atmosph...

The concentration C in ppm is also equal to the solute mass msolute in milligrams (mg) divided by the water solution volume Vsolution in liters (l):C(ppm) = msolute (mg) / Vsolution (l)Concentration of CO2The concentration of carbon dioxide (CO2) in the atmosphere is about 388ppm....
could be sediments, gases, metals or contaminates in the total mixture. The solution is most often a mixture of liquids or gases. One instance this could be used is if you have to find the parts per thousand (ppt) when given parts per million (ppm) of carbon dioxide in the atmosphere...
The unit ppm is used in several branches in different ways. In air pollution literature ppm applied to a gas, always means parts per million by volume or by mole. In combination with oxygen in carbon dioxide, carbon is found in the Earth's atmosphere; approximately each ppm corresponds to ...
