Yup....so many of the greenie weenies and Agenda 21 puppets like Noot (who are so very smart)do not realize that the average total of the earth's atmosphere is only 0.038% of the entire volume. Multiply that the entire mass (kg) of the entire atmosphere, including water vapor, and one will find that mankind is adding very little weight w/ regards to the total amount of C02 in the air. Our oceans hold a far far greater amount than any thing man produces.
Heck Mt Penitubo released more C02 in it's last major eruption than all the Co2 produced by all the earth's gas powered autos did that year.
Besides, plants love Co2 and welcom it.
