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.

Difference between Temperature and Humidity. â¢ Temperature is a measure of heat whereas humidity is a measure of the amount of water vapor present in air. â¢ Temperature of air is governed by solar radiation and higher solar energy means higher temperature of air.here is another concept called relative humidity which is a percentage of the actual amount of water vapor present in air to what air can hold at that temperature in theory. Hygrometers are used to measure humidity present in air. Let us see how humidity affects us in summers.
