The atmosphere is the source of carbon dioxide, which is utilised by plants in photosynthesis reduced to form carbon compounds. The total mass of carbon currently in the atmosphere is about 7 x 1017 g, ie, 700000 million tonnes Oceans regulate the CO2 content in the atmosphere and thus play a very important role. Sea water contains 50 times more CO2 than air, ie, about 70 % of total global carbon is found in oceans. This is in the form of carbonates and bicarbonates.
Which one of the flowing is the correct percentage of the two (out of the total of 4 ) green-house gases that contribute to the total global warming?
