Snow cover influences climate primarily through ___________ Atmospheric pressure Albedo effect Rainfall processes Wind circulation 2. 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 265 tCO₂e 100 tCO₂e 264 tCO₂e 3. Cyclones primarily form due to ___________ Warm ocean energy Cooling of ocean waters Rainfall processes Wind circulation only 4. The resilience of a climate system before reaching a tipping point is best described as ____________ Its radiative forcing Its capacity to absorb disturbances without shifting to an alternative state Its albedo Its emission rate 5. The characteristic that distinguishes tipping points from linear climate responses is ____________ Proportionality Predictability Gradual change Nonlinearity and abrupt transition 6. The loss of Arctic sea ice is considered a climate tipping element because it ____________ Amplifies warming through reduced albedo and increased heat absorption Reduces CO₂ emissions Stabilizes ocean currents Increases precipitation 7.

Climate tipping points are best characterized by __________ Gradual change in threshold Seasonal variability in threshold Irreversibility once a critical threshold is crossed Reversibility beyond threshold 9. Vegetation influences climate primarily through ___________ Wind circulation Soil processing Carbon and water cycles Atmospheric pressure 10. Which statement best explains why methane is both potent and short-lived?
