Snow cover influences climate primarily through ___________ Rainfall processes Wind circulation Albedo effect Atmospheric pressure 2. Cyclones primarily form due to ___________ Wind circulation only Cooling of ocean waters Rainfall processes Warm ocean energy 3. The loss of Arctic sea ice is considered a climate tipping element because it ____________ Amplifies warming through reduced albedo and increased heat absorption Stabilizes ocean currents Increases precipitation Reduces CO₂ emissions 4. If total emissions are 560 tCO₂e and are entirely due to methane (CH₄) (GWP₁₀₀ ≈ 28), what is the corresponding CH₄ emission? 20 t 15 t 25 t 10 t 5. Climate tipping points are best characterized by __________ Irreversibility once a critical threshold is crossed Gradual change in threshold Reversibility beyond threshold Seasonal variability in threshold 6. The resilience of a climate system before reaching a tipping point is best described as ____________ Its radiative forcing Its emission rate Its capacity to absorb disturbances without shifting to an alternative state Its albedo 7. The characteristic that distinguishes tipping points from linear climate responses is ____________ Gradual change Predictability Nonlinearity and abrupt transition Proportionality 8. 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)? 200 tCO₂e 264 tCO₂e 100 tCO₂e 265 tCO₂e 9. Which statement best explains why methane is both potent and short-lived?
