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