Short summary
Understanding rates of environmental change is critical to human and ecological health but is difficult when the processes are too slow or too small to observe directly. To overcome this limitation, we can use natural radioactive elements as virtual "clocks" to measure change. Here we describe a large number of measurements that have been used to develop soils as clocks or chronometers of change to atmospheric carbon and mercury (Hg) cycles.
