The ocean absorbs carbon dioxide from the atmosphere wherever air meets water wind causes waves and turbulence, giving more opportunity for the water to absorb the carbon dioxide fish and other animals in the ocean breathe oxygen and give off carbon dioxide (co 2 ), just like land animals. In the short term, the ocean absorbs atmospheric carbon dioxide into the mixed layer, a thin layer of water with nearly uniform temperature, salinity, and dissolved gases wind-driven turbulence maintains the mixed layer by stirring the water near the ocean’s surface.
Too much carbon dioxide may have caused earth’s worst mass extinction what is far more likely to affect the carbon content of the atmosphere is human activity the last time carbon.
The carbon dioxide greenhouse effect in the 19th century, scientists realized that gases in the atmosphere cause a greenhouse effect which affects the planet's temperature these scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. The co2 that nature emits (from the ocean and vegetation) is balanced by natural absorptions (again by the ocean and vegetation) therefore human emissions upset the natural balance, rising co2 to levels not seen in at least 800,000 years in fact, human emit 26 gigatonnes of co2 per year while co2 in the atmosphere is rising by only 15 gigatonnes per year - much of human co2 emissions is.
When the ocean–atmosphere system comes back to equilibrium, the concentration of carbon dioxide in the air will be 10 times greater than it is today, and the earth will be 22 degrees warmer. Without the greenhouse effect, the earth's temperature would be about −18 °c (-04 °f) compared to earth's actual surface temperature of approximately 14 °c (572 °f)  carbon dioxide is believed to have played an important effect in regulating earth's temperature throughout its 47 billion year history. The amount of carbon dioxide that the ocean can take from the atmosphere is controlled by both natural cycles and human activity atmosphere the global oceans are connected by deep currents (blue lines) and surface currents (red) stratification might wind up having competing effects on the overall carbon cycle, with saturation slowing.
Credit: nasa giss water vapor and clouds are the major contributors to earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide. Carbon dioxide and climate but the climatic effects due to carbon dioxide are almost entirely independent of the amount of these other two gases tons of carbon dioxide in the earth's.
The carbon dioxide greenhouse effect in 1938, gs callendar argued that the level of carbon dioxide was climbing and raising global temperature, but most scientists found his arguments implausible one possible answer was a change in the composition of the earth's atmosphere beginning with work by joseph fourier in the 1820s. The worst mass extinction in earth’s history may have been caused by huge amounts of carbon dioxide that accumulated in the atmosphere and the ocean after colossal volcanic eruptions in siberia. Eventually, the land and oceans will take up most of the extra carbon dioxide, but as much as 20 percent may remain in the atmosphere for many thousands of years the changes in the carbon cycle impact each reservoir excess carbon in the atmosphere warms the planet and helps plants on land grow more.
Human co2 is a tiny % of co2 emissions “the oceans contain 37,400 billion tons (gt) of suspended carbon, land biomass has 2000-3000 gt the atpmosphere contains 720 billion tons of co2 and humans contribute only 6 gt additional load on this balance. About a quarter to a third of all carbon dioxide emissions from our cars and factories are absorbed by the earth’s oceans much of it becomes “fixed” and stored in ocean plants like seagrass ocean plants absorb carbon just like forests and field grasses do.
