Which statement best explains why methane is both potent and short-lived? Strong radiative forcing but rapid atmospheric removal Low reactivity and low emissions High reactivity but weak radiative forcing No chemical reactivity 2. The loss of Arctic sea ice is considered a climate tipping element because it ____________ Reduces CO₂ emissions Increases precipitation Stabilizes ocean currents Amplifies warming through reduced albedo and increased heat absorption 3.

Snow cover influences climate primarily through ___________ Atmospheric pressure Albedo effect Rainfall processes Wind circulation 5. The resilience of a climate system before reaching a tipping point is best described as ____________ Its emission rate Its radiative forcing Its capacity to absorb disturbances without shifting to an alternative state Its albedo 6. 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)? 264 tCO₂e 100 tCO₂e 200 tCO₂e 265 tCO₂e 7. Cyclones primarily form due to ___________ Wind circulation only Rainfall processes Warm ocean energy Cooling of ocean waters 8. The characteristic that distinguishes tipping points from linear climate responses is ____________ Gradual change Nonlinearity and abrupt transition Proportionality Predictability 9. Vegetation influences climate primarily through ___________ Soil processing Atmospheric pressure Carbon and water cycles Wind circulation 10.
