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.

It's methane. While methane is a more potent greenhouse gas than CO2, there is over 200 times more CO2 in the atmosphere. Eg-CO2 levels are 380 ppm (parts per million) while methane levels are 1.75ppm.Hence the amount of warming methane contributes is calculated at 28% of the warming CO2 contributes. Here is a graph of the various forcings that influence climate (methane is CH4, right above CO2).g-CO2 levels are 380 ppm (parts per million) while methane levels are 1.75ppm.
