Climate extremes are primarily increasing due to ___________ Energy imbalance in the Earth’s system Increased rainfall Cooling of the climate system Wind circulation changes only 2. The concept of “tipping point cascades” in the climate system refers to ___________ Random, high-amplitude climate variability One climate tipping element triggering another through interconnected, self-reinforcing feedbacks Independent climate processes reaching thresholds simultaneously Seasonal climate cycles that are becoming more frequent 3. If emissions decrease from 40 GtCO₂ to 30 GtCO₂, what is the percentage reduction? 10% 30% 20% 25% 4. Climate equilibrium is achieved when __________ Rainfall ceases CO₂ concentrations stabilize Wind circulation stops Incoming solar radiation equals outgoing longwave radiation 5.
