Question

Fact: The Arctic latitudes are warming, which has released methane (a greenhouse gas) from thawing Arctic permafrost. This has increased the rate of warming in the Arctic. Systems analysis would label this as ________.
a) an open system
b) a closed system
c) a negative feedback loop
d) a positive feedback loop
e) an equilibrium condition

Answer 1

C. A negative feedback loop

Answer 2

Answer:

C. A negative feedback loop.

Explanation:

• As we know the melting of Arctic ice caps and polar regions due to global warming impact, and the release of methane a harmful natural gas in the environment from the Arctic system has created a negative impact upon the ecological system impacting badly and hence destroying it.

• The occurrence of a negative feedback is a way of earth saying that its resource cannot no longer bear the pressure and hence a balance needs to be made within this system, so system analysis predicts show this negative feedback as a disturbance being created.
