negative feedback
A sequence of interactions that damps or reduces the response to an initial perturbation.
For example, consider a surface that is subjected to an increase in incoming radiation. This change in the energy balance produces an increase in temperature which, by virtue of the Stefan– Boltzmann law, results in an increase in the radiation emitted by the surface. Thus, the interaction by temperature and radiation acts to partially counteract the original perturbation.
