Last December, Nigeria broke a centuries old promise.
 

Usually, by the second week of the month, the air turns crisp and white with Saharan dust. We reach for shea butter or vaseline for our cracked lips and pull heavy sweaters from the back of the wardrobe. But in 2025, the cold never came. Instead, the sun stayed fierce, the humidity clung to our skin, and the fans never stopped spinning.
 

Science tells us that the Northeast Trade Winds, the messengers of Harmattan, were bullied into silence. Warmer Atlantic waters kept the air moist, creating a literal wall of humidity that the dry Saharan breeze could not penetrate.
 

For many, it was a relief to skip the dusty coughs and the ashy skin. But for science and technology, it was a loud and silent alarm. Climate change is not just about melting glaciers in the Arctic; it is about the Christmas morning in Lagos or Kano where the breeze stayed warm. Nature is changing its script, and the missing sweater in our closet is the most chilling evidence we have.
