Fossil fuel extraction activities contribute to greenhouse gas emissions primarily through ___________ Carbon dioxide emissions only during extraction Nitrogen emissions from geological formations Methane leakage from oil and natural gas systems Release of oxygen during drilling processes 2. Methane (CH₄) is more potent as a greenhouse gas but less abundant in the atmosphere than ___________ Nitrous oxide (N₂O) Oxygen (O₂) Carbon dioxide (CO₂) Ozone (O₃) 3. Which of the following best represents a biogeochemical tipping point? Ice sheet collapse Wind circulation change Permafrost carbon release AMOC slowdown 4. The largest anthropogenic source of carbon dioxide (CO₂) emissions globally is ___________ Combustion of fossil fuels Volcanic eruptions Plant respiration Oceanic outgassing 5. The most effective long-term climate change mitigation strategy is ___________ Nitrous oxide control only Sustained reduction of carbon dioxide (CO₂) emissions Increasing atmospheric aerosols Methane reduction alone 6. The effectiveness of climate mitigation strategies is primarily determined by ___________ Technological availability only Nature of emission sources and greenhouse gas characteristics Economic cost alone Ambient temperature conditions only 7. The factor that most strongly influences comparisons of Global Warming Potential (GWP) among greenhouse gases is the ___________ Soil type influencing emissions Relative humidity of the atmosphere Wind speed affecting dispersion Selected time horizon over which warming is evaluated 8. 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 9. Methane (CH₄) is prioritized for near-term climate mitigation primarily because of its ___________ Low radiative efficiency Low emission contribution globally High short-term radiative forcing and warming impact Very long atmospheric lifetime 10.
