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.

Carbon dioxide causes about 20 percent of Earthâs greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent. The rest is caused by small particles (aerosols) and minor greenhouse gases like methane.Water vapor concentrations in the air are controlled by Earthâs temperature.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.
