Question:
Which two gases together contribute maximally to global warming?
Which two gases together contribute maximally to global warming?
Show Hint
- $CO_2$ → Highest contribution (due to abundance)
- $CH_4$ → High warming potential
- Together → Major drivers of global warming
Updated On: May 13, 2026
- $CO_2 + N_2O$
- $CH_4 + CFCs$
- $CO_2 + CFCs$
- $CO_2 + CH_4$
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Global warming is mainly caused by greenhouse gases that trap heat in the atmosphere. The most significant contributors are:
• Carbon dioxide ($CO_2$)
• Methane ($CH_4$)
Step 1: Analyze major contributors.
• $CO_2$ → Largest contributor due to high concentration
• $CH_4$ → More potent greenhouse gas (per molecule)
Step 2: Compare with other gases.
• $N_2O$ and CFCs → Strong but present in lower concentrations
Step 3: Final conclusion.
Thus, the two gases contributing maximally are: \[ CO_2 \text{ and } CH_4 \]
• Carbon dioxide ($CO_2$)
• Methane ($CH_4$)
Step 1: Analyze major contributors.
• $CO_2$ → Largest contributor due to high concentration
• $CH_4$ → More potent greenhouse gas (per molecule)
Step 2: Compare with other gases.
• $N_2O$ and CFCs → Strong but present in lower concentrations
Step 3: Final conclusion.
Thus, the two gases contributing maximally are: \[ CO_2 \text{ and } CH_4 \]
