Given below are two statements :

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.

In the light of the above statements, choose the most appropriate answer from the options given below:

The correct answer is Both statement I and Statement II are incorrect.
Key PointsStatement I: Negative feedback effects tend to increase the magnitude of climate change.

• This statement is incorrect.
• Negative feedbacks are processes in the climate system that act to counteract or dampen the effects of a change in the climate.
• For example, if the Earth's temperature increases due to increased greenhouse gases, negative feedbacks such as increased cloud cover or increased plant growth can help to reduce the warming.
  Therefore, negative feedback effects tend to decrease the magnitude of climate change, not increase it.

Statement II: Positive feedback effects tend to reduce the magnitude of climate change.

• This statement is also incorrect.
• Positive feedbacks are processes in the climate system that act to amplify or reinforce the effects of a change in the climate.
• For example, if the Earth's temperature increases due to increased greenhouse gases, positive feedbacks such as melting permafrost or decreased ice cover can further increase the warming.
• Therefore, positive feedback effects tend to increase the magnitude of climate change, not reduce it.

Overall, both statements are incorrect
