Cyclones primarily form due to ___________ Cooling of ocean waters Rainfall processes Warm ocean energy Wind circulation only 2. The loss of Arctic sea ice is considered a climate tipping element because it ____________ Stabilizes ocean currents Amplifies warming through reduced albedo and increased heat absorption Increases precipitation Reduces CO₂ emissions 3. Which statement best explains why methane is both potent and short-lived? No chemical reactivity Low reactivity and low emissions High reactivity but weak radiative forcing Strong radiative forcing but rapid atmospheric removal 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 emission rate Its albedo 5. 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 6. Climate tipping points are best characterized by __________ Gradual change in threshold Reversibility beyond threshold Irreversibility once a critical threshold is crossed Seasonal variability in threshold 7.
