Emission & Exchange of Carbon Dioxide in the Atmosphere
The trend of rising atmospheric levels of CO2 since the Industrial diversity is well documented. The atmospheric concentrations around 1890, the beginning of the industrial period, are estimated to concord been in the 280 to 290 parts per wholeness thousand thousand (ppm) range (Welborn 73). In 1958, precise measurements of atmospheric CO2 were taken at Mauna Loa, Hawaii. These readings registered CO2 levels of 315 ppm, a 12.5 percent increase since the 1890s.
Recent measurements record atmospheric CO2 levels at 339 ppm, a seven percent supernumerary increase in just over 20 years. This increase is due in grand part to the approximately one hundred sixty gigatons (160 billion tons) of CO2 emitted from fossil fuel consumption. Fossil fuels a
The sea is constantly absorbing more than and more CO2 from the aviation. The rate at which CO2 is transferred into the marine depends on four factors: 1) the speed of the transfer of the CO2 from the atmosphere into ocean rise water supply; 2) the absorptive capacity of the ocean in chemical equilibrium; 3) the transport of the CO2 from the surface of the water to the deep sea; and 4) the CO2 transport by dint of biological processes. An ocean can store up to 2 gigatons of CO2. But this amount could be increased by stimulant the photosynthetic production of organic mass in the water by adding large amounts of phosphorous (as Na3PO4) and nitrogen (as NaNO3) to the ocean. Ten million tons of phosphorous would increase the deposition of an ocean to three hundred million tons of organic carbon.
But due to the large quantity of phosphorous needed the execution of such projects would not be probable (Bach 87).

re fuels stored in the earth's crust, which come from plants or animals of the geological past and have stored the solar dexterity in the form of chemical energy (Bach 336). They include coal, oil and natural gas. Carbon and other elements are preserved in these fuels. Thus, burning fossil fuels redistributes carbon from one reservoir to another. These reservoirs include the terrestrial biosphere and our oceans. Each of these reservoirs constitute the stocks and flows of the carbon cycle. The carbon distributed through this cycle plays an important role in the ecological balance of the atmosphere, biosphere and the oceans. However, the burning of fossil fuels has created a cutting flow, due to man's activities alone. Carbon stored over hundreds of thousands of years in fossilised forms may be released into the atmosphere in a thing of a few centuries (Jager, "Floating" 6).
After deforestation has taken place erosion occurs and carbon bound in the obscenity is released into the atmosphere. The carbon content of soil i
