Climate Change Global Warming

Step 1: Understanding the Concept:
The question asks to arrange greenhouse gases in ascending order (least to most) of their total contribution to the enhanced greenhouse effect (global warming). This contribution depends on both the gas's atmospheric concentration and its Global Warming Potential (GWP) per molecule.

Step 3: Detailed Explanation:
The overall contribution of each gas to global warming is a product of its abundance and warming efficiency. Based on current data from sources like the IPCC, the approximate contributions are:

This corresponds to the sequence (C), (B), (A), (D).

Step 4: Final Answer:
The correct ascending order of contribution to global warming is (C) CFCs, (B) N $_2$ O, (A) CH $_4$ , (D) CO $_2$ .
