The Earthâs atmosphere is 78 percent nitrogen, 21 percent oxygen and 1 percent other gases, including about 0.04 percent carbon dioxide.And yes, Earthâs CO2 concentration stood at 400 parts per million in May 2015.Earthâs CO2 levels have been increasing in recent decades due to human activities and also natural factors, and some estimates say as little as 3 or 4 percent of carbon dioxide in the atmosphere is due to humans.nd yes, Earthâs CO2 concentration stood at 400 parts per million in May 2015.

The 2.3 X 1012 (2,300 billion) tons of carbon dioxide in the earth's present atmosphere constitute some .03 per cent of its total mass. The quantity of carbon dioxide in the atmosphere is determined by the amounts supplied and withdrawn from three other great reservoirs: oceans, rocks and living organisms. The oceans contain some 1.3 X 1014 tons of carbon dioxideâabout 50 times as much as the air. Some of the gas is dissolved in the water, but most of it is present in carbonate compounds. The oceans exchange about 200 billion tons of carbon dioxide with the atmosphere each year.
