The most effective long-term climate change mitigation strategy is ___________ Increasing atmospheric aerosols Sustained reduction of carbon dioxide (CO₂) emissions Methane reduction alone Nitrous oxide control only 2. Deforestation is considered a “double impact” on climate change because it ___________ Influences only hydrological processes Affects only soil properties without atmospheric consequences Increases atmospheric oxygen concentrations Releases stored carbon and simultaneously reduces carbon sink capacity 3. The effectiveness of climate mitigation strategies is primarily determined by ___________ Nature of emission sources and greenhouse gas characteristics Ambient temperature conditions only Economic cost alone Technological availability only 4. Methane (CH₄) is prioritized for near-term climate mitigation primarily because of its ___________ Low emission contribution globally Very long atmospheric lifetime High short-term radiative forcing and warming impact Low radiative efficiency 5. The largest anthropogenic source of carbon dioxide (CO₂) emissions globally is ___________ Volcanic eruptions Combustion of fossil fuels Oceanic outgassing Plant respiration 6. The factor that most strongly influences comparisons of Global Warming Potential (GWP) among greenhouse gases is the ___________ Relative humidity of the atmosphere Wind speed affecting dispersion Soil type influencing emissions Selected time horizon over which warming is evaluated 7. Methane (CH₄) is more potent as a greenhouse gas but less abundant in the atmosphere than ___________ Ozone (O₃) Carbon dioxide (CO₂) Nitrous oxide (N₂O) Oxygen (O₂) 8. Which of the following best represents a biogeochemical tipping point? AMOC slowdown Wind circulation change Ice sheet collapse Permafrost carbon release 9. Improved manure management practices primarily reduce emissions of ___________ Oxygen released Nitrogen Methane and nitrous oxide Carbon dioxide 10. Fossil fuel extraction activities contribute to greenhouse gas emissions primarily through ___________ Methane leakage from oil and natural gas systems Nitrogen emissions from geological formations Carbon dioxide emissions only during extraction Release of oxygen during drilling processes Loading … Question 1 of 10Climate Change MCQs Set 29 (200+ Questions with Answers) Climate Change MCQs Set 29 (200+ Questions with Answers) 1.
