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.

Since temperature is related to air pressure. As the sun heats the ground or ocean, warning them, the air near the ground or ocean warms and becomes less dense. As this happen â¦ s the air begins rising, which lowers the air pressure at the Earth's surface.  In detecting atmospheric pressure, a barometer measures the weight of the column of air that stretches directly above it from the Earth's surface to the top of the atmosphere.hen the temperature is higher the air pressure lowers and the weight of the air is lower. When air is warmer the molecules spera â¦ te and there are less molecules that can cause pressure. 3 people found this useful.
