The study investigates the concurrent record-breaking heatwaves and precipitation extremes in 2022, linking them to warming and ice/snow melting in the Earth's three Poles (Arctic, Antarctic, and Tibetan Plateau). The warming amplified Rossby waves and shifted westerly jet streams, intensifying heatwaves in mid-high latitudes and extreme precipitation in Asia. The study highlights the significant role of three Poles warming in driving amplified concurrent extremes, offering valuable insights for global climate predictions and disaster prevention.
