Positive feedback loops do not go on forever; they are ultimately stopped by negative feedback loops once the process they were used for is complete. A positive feedback causes instability for a relatively short period. Systems in Water and Carbon Cycles A negative feedback decreases the amount of change by reducing some of the inputs, returning the system to stability. This leads to the growth of ice sheets, which are reflective, meaning more solar radiation is reflected away from the earth leading to further cooling of the earth. Without additional sediment, it will eventually be overwhelmed by the increase in sea level and drown in place. Consider a barrier island system that is subjected to a rise in sea level.

Feedback is most powerful when it is timely (sorry annual performance review ). As you have just learned, sea level can fluctuate across a range of scales, from water level change due to tides to longer term changes driven by climate and the storage or release of ocean water in glaciers and ice sheets.
