Give an example of a process that would be considered a positive feedback mechanism during a period of warming on the earth?

If the temperature of the body goes outside of this range‚ there is a system in body called the negative feedback system‚ which is where the systems attempt a normal body temperature. When temperatures go outside of this range in a particular place in the body‚ a stimulus to a receptor sends nerve impulses to a regulating centre in the brain. The brain sends
