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 2. Cyclones primarily form due to ___________ Warm ocean energy Cooling of ocean waters Wind circulation only Rainfall processes 3. Which statement best explains why methane is both potent and short-lived?

Climate tipping points are best characterized by __________ Gradual change in threshold Irreversibility once a critical threshold is crossed Seasonal variability in threshold Reversibility beyond threshold 5. 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 6. Vegetation influences climate primarily through ___________ Atmospheric pressure Wind circulation Soil processing Carbon and water cycles 7. Snow cover influences climate primarily through ___________ Rainfall processes Albedo effect Wind circulation Atmospheric pressure 8.
