Methane (CH₄) mitigation policies can produce rapid climate benefits primarily because methane has a ___________ Low global warming potential Short atmospheric lifetime High emission rate Low radiative forcing 2. Why is CO₂ assigned a GWP of 1? It is most abundant It has the shortest lifetime It has no warming effect It serves as the baseline reference gas 3. Precision agriculture can mitigate high global warming potential (GWP) emissions primarily by ________ Reducing crop yield Increasing fertilizer use Increasing methane emissions Optimizing nitrogen application to reduce N₂O emissions 4. Which factor directly determines the accumulation of Growing Degree Days (GDD) in crop growth analysis? Temperature above the base (threshold) temperature Crop growth habit (C3, C4, CAM) Frost-free days Root depth and type 5. Carbon budgets are primarily determined based on __________ Rainfall Cumulative CO₂ emissions Annual emissions Temperature 6. Which combination is correctly matched? DTR – annual variation Q₁₀ – temperature sensitivity of biological processes ATR – daily variation GDD – rainfall index 7. Which factor primarily influences surface albedo? Surface characteristics Wind speed Latitude only Atmospheric pressure 8. Which gas has the highest GWP over 100 years among common GHGs? N₂O CO₂ O₂ CH₄ 9. Which agricultural approach is most effective in reducing the carbon footprint while maintaining productivity? More irrigation More fertilizer application Precision nutrient and water management Afforestation 10. A climate mitigation strategy focusing only on CO₂ may be insufficient because:__________ CO₂ concentration is low in the atmosphere Methane is absent in the troposphere Ozone dominates in the stratosphere Non-CO₂ gases also contribute significantly Loading … Question 1 of 10 Climate Change MCQs Set 6 (200+ Questions with Answers)
