The important point here is uncertainty.
While the UN and the IPCC assume that climate feedbacks are positive, ie that the responses within the climate system to increasing carbon dioxide will have the net effect of making any warming worse, the reality is that we just don't know if this is true or not, and here we have an example where the system changes to possibly mitigate against any warming effect.
However, a knowledge of geological history should have prepared people for this. We know that levels of carbon dioxide in the atmosphere have been greater in the past without causing the kind of doomsday outcomes the Greens keep droning on and on about, so we should expect that the dynamic responses of the system will probably tend towards returning it to a reasonable equilibrium.
