What does the Intergovernmental Panel on Climate Change (IPCC) emphasize regarding reductions in greenhouse gas (GHG) emission?1.Gradual and limited reductions are enough.2.Deep, rapid and sustained reductions are essential.Select the correct answer from the codes given below:

1. A

   Both 1 and 2

   Option (a) claims that both statements 1 and 2 are correct according to the IPCC. This is incorrect because statement 1 contradicts the scientific consensus on urgent climate action.

2. B

   Neither 1 nor 2

   Option (b) claims that neither statement is correct, which disregards the accurate assertion made in the second statement regarding necessary emission cuts.

3. C

   Only 1

   Option (c) claims that only statement 1 is correct, endorsing gradual and limited reductions which the IPCC explicitly warns are insufficient to avoid severe climate impacts.

4. D

   Only 2

   is (d) because the Intergovernmental Panel on Climate Change (IPCC) reports consistently emphasize that deep, rapid, and sustained reductions in greenhouse gas emissions are essential to limit global warming to 1.5 degrees Celsius and prevent catastrophic climate disruption.

Summary. Official key is (d) stating that only statement 2 is correct regarding greenhouse gas emission reductions. The IPCC assessment reports highlight that incremental measures are no longer adequate to address the escalating climate crisis. Therefore, statements advocating for gradual reductions are rejected by scientific bodies. Only deep, rapid, and sustained emission cuts can stabilize global temperature rise effectively.
