Climate tipping points are best characterized by __________ Reversibility beyond threshold Seasonal variability in threshold Gradual change in threshold Irreversibility once a critical threshold is crossed 2. The characteristic that distinguishes tipping points from linear climate responses is ____________ Predictability Nonlinearity and abrupt transition Gradual change Proportionality 3. Cyclones primarily form due to ___________ Warm ocean energy Rainfall processes Wind circulation only Cooling of ocean waters 4. The resilience of a climate system before reaching a tipping point is best described as ____________ Its radiative forcing Its emission rate Its albedo Its capacity to absorb disturbances without shifting to an alternative state 5. 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 264 tCO₂e 100 tCO₂e 6. Vegetation influences climate primarily through ___________ Wind circulation Carbon and water cycles Atmospheric pressure Soil processing 7.
