Feedback loops are important because they allow organisms and the environment to

• change based on new inputs

• fall apart

• change based on new outputs

• maintain balance

Negative feedback loops try to maintain

• equilibrium

• chaos

• precession

• change

As the Earth warms, upper layers of permafrost melt, producing waterlogged soil above frozen ground. Methane gas is released into the environment. The greenhouse effect is enhanced. The Earth warms, melting more permafrost.

As the Earth warms, ice cover melts, exposing soil or water. Albedo decreases. More energy is absorbed by the Earth’s surface. Global temperature rises. More ice melts.
