    "author": "Martina Klose",
    "description": "Every year billions of tonnes of mineral dust rise from the world's deserts. Martina Klose follows that dust from gusts on a Saharan surface to clouds, radiation, and distant ecosystems. This short explains how particles too small to see brighten and darken the sky, seed ice in clouds, fertilise oceans, and why dust remains one of the loudest open questions in climate models.",

Because emission depends on gusts and surface details that models cannot resolve, dust remains a major source of uncertainty in climate simulations."
