The resilience of a climate system before reaching a tipping point is best described as ____________ Its radiative forcing Its emission rate Its capacity to absorb disturbances without shifting to an alternative state Its albedo 2. If total emissions are 560 tCO₂e and are entirely due to methane (CH₄) (GWP₁₀₀ ≈ 28), what is the corresponding CH₄ emission? 15 t 25 t 20 t 10 t 3. The loss of Arctic sea ice is considered a climate tipping element because it ____________ Amplifies warming through reduced albedo and increased heat absorption Stabilizes ocean currents Increases precipitation Reduces CO₂ emissions 4. The characteristic that distinguishes tipping points from linear climate responses is ____________ Nonlinearity and abrupt transition Proportionality Predictability Gradual change 5. Which statement best explains why methane is both potent and short-lived?
