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