Show answer & explanation
Correct answer: A
This scenario describes a positive feedback loop. As global temperatures rise, wetlands release more methane (a potent greenhouse gas). This additional methane traps more heat in the atmosphere, leading to further temperature increases and even more methane release. This self-reinforcing cycle amplifies the initial change, characteristic of positive feedback mechanisms in climate systems.
