Climate tipping points are best characterized by __________ Irreversibility once a critical threshold is crossed Reversibility beyond threshold Seasonal variability in threshold Gradual change in threshold 2. The resilience of a climate system before reaching a tipping point is best described as ____________ Its albedo Its radiative forcing Its emission rate Its capacity to absorb disturbances without shifting to an alternative state 3. Snow cover influences climate primarily through ___________ Wind circulation Albedo effect Atmospheric pressure Rainfall processes 4. The loss of Arctic sea ice is considered a climate tipping element because it ____________ Stabilizes ocean currents Amplifies warming through reduced albedo and increased heat absorption Reduces CO₂ emissions Increases precipitation 5. Which statement best explains why methane is both potent and short-lived? Strong radiative forcing but rapid atmospheric removal No chemical reactivity Low reactivity and low emissions High reactivity but weak radiative forcing 6. The characteristic that distinguishes tipping points from linear climate responses is ____________ Gradual change Proportionality Predictability Nonlinearity and abrupt transition 7. Replacing emissions of 1 tonne of N₂O with 1 tonne of CO₂ results in a reduction of how many tonnes of CO₂-equivalent (GWP₁₀₀ basis)? 100 tCO₂e 265 tCO₂e 200 tCO₂e 264 tCO₂e 8. If total emissions are 560 tCO₂e and are entirely due to methane (CH₄) (GWP₁₀₀ ≈ 28), what is the corresponding CH₄ emission? 25 t 20 t 10 t 15 t 9. Cyclones primarily form due to ___________ Cooling of ocean waters Rainfall processes Warm ocean energy Wind circulation only 10. Vegetation influences climate primarily through ___________ Soil processing Wind circulation Atmospheric pressure Carbon and water cycles Loading … Question 1 of 10Climate Change MCQs Set-23 (200+ Questions with Answers) Climate Change MCQs Set-23 (200+ Questions with Answers) 1.
