1. Question
Which of the following is the primary greenhouse gas responsible for global warming?
CorrectAnswer: (b)
Explanation:
• Carbon dioxide (CO₂) is the largest contributor to global warming due to its volume and long atmospheric lifetime.
• Methane and nitrous oxide have higher global warming potentials but are emitted in smaller quantities.
• CFCs contribute to ozone depletion and also have warming effects but are largely phased out under the Montreal Protocol.IncorrectAnswer: (b)

2. Question
Which Indian state is most vulnerable to sea-level rise due to climate change?
CorrectAnswer: (d)
Explanation:
• West Bengal, especially the Sundarbans region, is highly vulnerable to sea-level rise and coastal flooding, threatening mangroves, biodiversity, and millions of people.
• Gujarat and Kerala also face coastal risks but to a lesser extent; Rajasthan is landlocked.IncorrectAnswer: (d)

3. Question
Which of the following climate phenomena are linked to the variability of the Indian monsoon?
1. El Niño Southern Oscillation (ENSO)
2. Indian Ocean Dipole (IOD)
3. Atlantic Multidecadal Oscillation (AMO)
Select the correct combination:CorrectAnswer: (a)
Explanation:
• ENSO and IOD strongly influence the intensity and distribution of the Indian monsoon.
• AMO has some long-term effects on climate but less direct influence on monsoon variability.IncorrectAnswer: (a)
Explanation:
• ENSO and IOD strongly influence the intensity and distribution of the Indian monsoon.
• AMO has some long-term effects on climate but less direct influence on monsoon variability. - Question 4 of 5
4. Question
Which of the following are projected impacts of climate change on India’s agriculture?
1. Reduced crop yields due to heat stress
2. Increased water scarcity for irrigation
3. Increased pest and disease outbreaks
4. Uniform increase in agricultural productivity
Select the correct answer:CorrectAnswer: (a)
Explanation:
• Climate change causes heat stress, irregular rainfall, and water shortages affecting crop productivity.
• Pest and disease prevalence may increase due to changing climate conditions.
• Agricultural productivity is expected to decline or become more variable, not uniformly increase.IncorrectAnswer: (a)
Explanation:
• Climate change causes heat stress, irregular rainfall, and water shortages affecting crop productivity.
• Pest and disease prevalence may increase due to changing climate conditions.
• Agricultural productivity is expected to decline or become more variable, not uniformly increase. - Question 5 of 5
5. Question
The Paris Agreement’s goal to limit global warming to well below 2°C primarily requires countries to:
CorrectAnswer: (b)
Explanation:
• The Paris Agreement focuses on reducing emissions to net-zero around 2050 to limit warming.
• While reducing fossil fuels and deforestation are part of strategies, the agreement sets flexible nationally determined contributions (NDCs), not immediate bans or geoengineering mandates.IncorrectAnswer: (b)
Explanation:
• The Paris Agreement focuses on reducing emissions to net-zero around 2050 to limit warming.
• While reducing fossil fuels and deforestation are part of strategies, the agreement sets flexible nationally determined contributions (NDCs), not immediate bans or geoengineering mandates.
