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