Climate-related displacement is already a global reality. Every year, the lives of millions of people are affected when they are displaced by the impacts of weather and climate hazards. Some of the largest disasters make the international headlines, but most disasters do not even make the national news.
Sand and dust storms are common meteorological hazards in arid and semi-arid regions. They are usually caused by thunderstorms – or strong pressure gradients associated with cyclones – which increase wind speed over a wide area. These strong winds lift large amounts of sand and dust from bare, dry soils into the atmosphere, transporting them hundreds to thousands of kilometres away. Some 40% of aerosols in the troposphere (the lowest layer of Earth’s atmosphere) are dust particles from wind erosion.
