    When CO2 is emitted into the atmosphere, about half of it is almost immediately removed and added to the surface ocean and to forests. The remaining half, called the airborne fraction, stays in the atmosphere for many hundreds of years awaiting the very slow transfer to the surface ocean and then into the deep ocean. So even if we stopped emitting CO2 today, it would take centuries on centuries (about 1,000 years), before CO2 concentrations would approach that of preindustrial times.
    One might expect that as CO2 decreases (albeit slowly) from a cessation of CO2 emissions, at least the climate would slowly cool, but it doesn’t. Some of the warming from the increased CO2 has been stored in the ocean, and as CO2 decreases this excess heat is slowly released from the ocean keeping temperatures elevated for a thousand years or so.
    A thousand years is a long time to wait to cool down. Do we really want to keep turning up the hot water?

    There is just one problem. Science shows us that as CO2 increases it has a DIMINISHING effect on the environment.

    What science is that? Bald statement means zilch. No referance, no credibility.

    In other words, you are to stupid to grasp the concept so you ignore it, but hey thanks for playing.

    In other words you don't have a source or are just too lazy to take the minute to post a link. Besides it is just so much more satisfying to call someone you disagree with stupid, right?
