I found this article, information released yesterday to the public through
ErekAlert.com and it seems to have quite a valid point with its
research.
I am fully aware that we can never know 100% what will happen to our planet from the effects of pollution, but these scientists seem to theorize about
the saturation point peak and the resulting decrease.
In their models, Mokhov and Eliseev found that although climate–carbon cycle feedback grows initially, it then peaks and eventually decreases to a
point where the feedback ceases. If we succeed in slowing down the rate of emissions, the peak would be reached much later. However, a steep increase
in emissions would bring the peak in coupling between climate and carbon emissions even closer.

It would seem that they believe that after saturation point there would be a resulting decrease, and also that saturation point is inevitable.
Do we sit back and wait, bringing about the decrease sooner or should we still be trying to do something about it?
Please read the full article, it is brief but has more detail to back up the argument.
