Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:Negative feedback effects tend to increase the magnitude of climate change.
Statement II:Positive feedback effects tend to reduce the magnitude of climate change.
ABoth Statement I and Statement II are correct
BBoth Statement I and Statement II are incorrect ✓ Correct
CStatement I is correct but Statement II is incorrect
DStatement I is incorrect but Statement II is correct
Correct answer: (B) Both Statement I and Statement II are incorrect
Explanation
Both feedback claims are stated in reverse, so each is wrong.
Negative feedback actually damps and reduces the magnitude of climate change, not increases it.
Statement 1 is therefore incorrect.
Positive feedback actually amplifies and increases the magnitude of change, not reduces it.
Statement 2 is therefore incorrect as well.
Melting ice lowering surface reflectivity is a classic warming positive feedback.
