The diagram consists of a set of words and arrows. Causal loop diagrams are accompanied by a narrative which describes the causally closed situation the CLD describes. Closed loops, or causal feedback loops, in the diagram are very important features of CLDs because they may help identify non-obvious vicious circles and virtuous circles.
Thus, a positive feedback loop is formed, which continues until the negative feedbacks bring the system to equilibrium. [ 7 ] : 969 Increases in atmospheric water vapor have been detected from satellites , and calculations based on these observations place this feedback strength at 1.85 ± 0.32 m 2 /K.

Audio feedback (also known as acoustic feedback, simply as feedback, or the Larsen effect) is a special kind of positive feedback which occurs when a sound loop exists between an audio input (for example, a microphone or guitar pickup) and an audio output (for example, a loudly-amplified loudspeaker).
When the body temperature is too high or too low, the blood vessels will change size accordingly to bring the body’s temperature back to normal. In this diagram, the tube-shaped objects represent blood vessels and the red and blue objects represent thermometers. The middle blood vessel is sized for a blood vessel at normal body temperature.
Any system can be drawn as a diagram set up with circles of causality – including actions, feedbacks and delays. [1] Reinforcing feedback (or amplifying feedback) accelerates the given trend of a process. If the trend is ascending, the reinforcing (positive) feedback will accelerate the growth. If the trend is descending, it will accelerate ...
The causal loop diagram of the new product introduction may look as follows: Causal loop diagram of New product adoption model. There are two feedback loops in this diagram. The positive reinforcement (labeled R) loop on the right indicates that the more people have already adopted the new product, the stronger the word-of-mouth impact. There ...
A positive feedback loop speeds up a process. Meadows indicates that in most cases, it is preferable to slow down a positive loop, rather than speeding up a negative one. The eutrophication of a lake is a typical feedback loop that goes wild. In a eutrophic lake (which means well-nourished), much life, including fish, can be supported.
