Q1. Explain the concept of radiative forcing and examine the role of CO2 in contributing to global warming compared to other greenhouse gases. (10 M)
Difficulty Level: Medium
Reference: IE
Why the Question? CO2 is one of the most important GHGs in the atmosphere and is the primary driver of anthropogenic climate change. Key Demand of the Question Define radiative forcing (RF) and its relevance to global warming. Compare CO2’s contribution to RF with other greenhouse gases. Highlight why CO2 is the primary driver despite other gases being more potent. Structure of the Answer Introduction Briefly mention CO2 as a major contributor. Body Explain radiative forcing and how greenhouse gases trap heat. Discuss CO2’s role in contributing to RF through its abundance and longevity. Provide a comparative analysis with other gases like CH4 and HFCs in terms of potency, atmospheric abundance, and persistence. Conclusion Summarize the dominance of CO2 in driving global warming due to its sustained presence and cumulative emissions, stressing the need for mitigation.
