Vegetation influences climate primarily through ___________ Atmospheric pressure Wind circulation Carbon and water cycles Soil processing 2. If total emissions are 560 tCO₂e and are entirely due to methane (CH₄) (GWP₁₀₀ ≈ 28), what is the corresponding CH₄ emission? 10 t 25 t 15 t 20 t 3. Cyclones primarily form due to ___________ Warm ocean energy Wind circulation only Cooling of ocean waters Rainfall processes 4. The characteristic that distinguishes tipping points from linear climate responses is ____________ Proportionality Nonlinearity and abrupt transition Gradual change Predictability 5. Climate tipping points are best characterized by __________ Seasonal variability in threshold Gradual change in threshold Irreversibility once a critical threshold is crossed Reversibility beyond threshold 6. The resilience of a climate system before reaching a tipping point is best described as ____________ Its capacity to absorb disturbances without shifting to an alternative state Its emission rate Its albedo Its radiative forcing 7.
