    "description": "Monsoons feed half of humanity, yet textbooks still explain them as giant sea breezes. Simona Bordoni dismantles that picture in this short. She shows the monsoon as a planetary-scale shift of the tropical overturning circulation, explains why rain bands jump rather than drift with the sun, and what this modern theory changes for how monsoons respond to a warming world.",

        "summary": "The old land-sea-contrast story cannot explain monsoon onset's suddenness. Seen as a reorganisation of the Hadley circulation driven by atmospheric energetics, the abrupt jumps, the timing, and the differences between monsoon systems fall into place. The energetic view also gives sharper predictions of how monsoon rains shift as the planet warms."
