Positive Feedback Mechanism
A feedback loop where a change produces effects that amplify the original change, destabilizing systems.
Real World
The 2019–2020 Australian bushfires released an estimated 830 million tonnes of CO₂, which reduced vegetation cover, lowered carbon absorption, and increased the likelihood of future fires — a classic positive feedback.
Exam Focus
Always contrast positive feedback with negative feedback — explain that positive amplifies change while negative dampens it.
