The oceans absorb much CO2 in a process thatâs called hydration. The relation between temperature and CO2 is that CO2 increases lag temperature increases by 800 which is due to sea temperatures. The ability of sea water to absorb CO2 is dependent upon the water temperature.he oceans absorb much CO2 in a process thatâs called hydration.

So while carbon dioxide contributes less to the overall greenhouse effect than water vapor, scientists have found that carbon dioxide is the gas that sets the temperature. Carbon dioxide controls the amount of water vapor in the atmosphere and thus the size of the greenhouse effect.ising concentrations of carbon dioxide are warming the atmosphere. The increased temperature results in higher evaporation rates and a wetter atmosphere, which leads to a vicious cycle of further warming. (Photograph Â©2011 Patrick Wilken.
