Sourcing atmospheric CO2

I'm searching for responses to this question:

If global atmospheric CO2 rise is a result of anthropogenic CO2 production, why does the CO2 record exhibit a steady rise to present levels. Why don't atmospheric CO2 levels reflect changing economic climate?

In other words, if CO2 production looks like this:




why does atmospheric CO2 levels look like this:



There are obviously many interactions among CO2 sources and CO2 sinks in the atmosphere, the ocean and the earth. Some of these sinks may "smooth out" the curve of atmospheric CO2.

But doesn't that mean that the effects of "smoothing out" processes are stronger than the effects of anthropogenic CO2?

  1. You're an idiot and a Denier. Climate change, like gravity, is an observed phenomena. Ignoring it doesn't make you right.

    Go back to school, get a PhD in Climatology or atmospheric physics, publish your own research AND THEN YOU MIGHT HAVE A POINT.

    Until then, please, STFU.

    BTW_ desecrating the works of Edward Abbey this way is truly beyond the pale.

  2. Thanks for your constructive criticism, Pangolin.

    Yes, I must admit, I feel like an idiot sometimes, trying to explain the painfully obvious to those who will not see.

    However, in this post, I deny nothing, merely asking a simple question.

    Does Pangolin have an answer?

    Oh, and by the way, I already have a Ph.D. and I have already published.

    As to the works of Ed Abbey, they stand on their own. These scribblings have no effect on the past.

  3. I'll offer some constructive criticism. It seems to me that if you were to examine these graphs using the same time scale (1960-2004), they would reflect the same conclusion: the increase in global carbon emissions and global levels of CO2 appear to mirror each other fairly closely, both increasing at a steady rate. The smoother line of CO2 levels is easily attributable to the multitude of variables involves, while the carbon emissions include very few variables, specifically, four.

    The "sinks," etc. you refer to may have more effects in the overall CO2 levels than anthropogenic contributions, but I don't think that means they would cancel them out. One can spot specific periods in those graphs, especially in the mid 70s, where carbon emissions declined and the rate of atmospheric CO2 slowed, but was still increasing. To me, this suggests a pretty close link.
