Levels of carbon dioxide are maintained when the amount of carbon dioxide being absorbed by the oceans and plant life equals the amount of carbon dioxide created by all natural and man made sources. When these sources exceed the ability to absorb, the levels go up.
The major threat to this equilibrium is, of course, the burning of fossil fuels (coal, oil and natural gas), which releases carbon dioxide hidden away for millions of years.
Carbon dioxide levels will level out only when we stop burning fossil fuels (coal, oil and natural gas), and after the great forests of the world grow again. Photosynthesis from growing plants is the only way to remove the extra carbon dioxide that we have put into the air.
Carbon dioxide is decreased.
Ground level carbon dioxide is a pollutant. It reaches to atmosphere by westerly's.
Carbon dioxide (CO2) is a gas that mixes very easily, so there are no regional variations. So the carbon dioxide level in Bangladesh is the same as it is all round the world.The carbon dioxide levels for 2012 are 392 ppm (parts per million).
There is no known way that humans can economically remove carbon dioxide from the atmosphere; all we can really do is reduce our emissions of carbon dioxide and slow down the rate at which atmospheric carbon dioxide levels are increasing. The surface waters of the ocean do absorb some carbon dioxide from the atmosphere as atmospheric carbon dioxide level increase, but there is little interchange betwen the warm upper ocean and the deep layers. However over a period of several thousand years, there is sufficient interchange to absorb large volumes of carbon dioxide, allowing the atmospheric concentration to return more or less to normal. Afforestation. Planting trees will remove carbon dioxide from the atmosphere.
The oceans help to keep the carbon dioxide level in the atmosphere low by dissolving a large portion of CO2 from the atmosphere. Unfortunately, the increased CO2 in the atmosphere is causing the oceans to become more acidic.

the atmosphere in the Permian had 115 % of modern oxygen level and 3x the amount of carbon dioxide- pre-industrial level.
