Soil carbon "sequestration" is all the rage now a days, but very rarely does anyone define the time-frame of "sequester". Usually folks are only looking at changes to soil carbon *content*, and assuming those changes are permanent. They are not. Here we show that soil carbon *content* is de-coupled from how long that soil carbon stays in soil (i.e. having more carbon in soils does not necessary mean that carbon sticks around for longer periods of time).
