Consider the following pairs:1. Weakening of the Polar Vortex: Disrup...
1. Weakening of the Polar Vortex: Disruption of atmospheric waves allowing warm air entry - Correctly matched. The weakening of the polar vortex allows warm air to infiltrate the Antarctic region, contributing to the heatwave.
2. Reduced Antarctic Sea Ice: Increased sunlight reflection leading to cooler temperatures - Incorrectly matched. Reduced sea ice actually decreases sunlight reflection (albedo effect), causing more sunlight to be absorbed by the ocean, leading to higher temperatures.
3. Accelerated Warming in Antarctica: Warming rate nearly double the global average - Correctly matched. Antarctica is warming at a rate of 0.22°C to 0.32°C per decade, which is nearly double the global average.
4. Albedo Effect: Reduced ice cover leading to increased sunlight absorption - Correctly matched. The reduction of ice decreases the Earth's albedo, leading to more sunlight absorption by the ocean, resulting in additional warming.
Thus, three pairs are correctly matched.
