Discussion
Assertion (A): Internal variability can produce climate fluctuations with no external cause at all.
Reason (R): The coupled ocean atmosphere system has its own modes of oscillation.
Answer: A
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the reason gives the mechanism. The ocean and atmosphere are coupled non-linear fluids with their own modes of oscillation, so the system can move from one state to another with no push from outside - El Nino being the clearest case. This is why detecting a forced trend requires an estimate of the internal variability against which to judge it.
