- Black Sunday (April 14, 1935) was the worst dust storm in US history, causing devastation across six states from Nebraska to Texas, turning day into night and leading to crop destruction, livestock deaths, and human fatalities from suffocation or dust pneumonia.
- Modern dust storms remain a health hazard, causing pneumoconiosis, increasing hospitalizations, and exacerbating conditions like asthma; fine particles can enter the bloodstream and brain, raising risks of heart issues and strokes.
- Dust storms can transport dangerous bacteria or fungal spores, linking to diseases like bacterial meningitis in Africa and Valley Fever in the US, with cases rising due to hotter, drier conditions from global heating.
- Recent dust storm activity centers in drought states like New Mexico, Arizona, and Texas, with record numbers of storms in 2025, affecting air quality, grounding flights, and causing power outages.
- Economic costs are substantial, with dust storms costing billions annually in North Africa, the Middle East, and the US, impacting farming, transport, energy, and health, including damage to homes and increased energy costs.
- Global dust storms are increasing due to persistent droughts worsened by global heating and poor land management, affecting 330 million people across 150 countries, with dust transported thousands of miles, as seen from Africa to the Caribbean and Europe.
- The 1930s Dust Bowl resulted from poor farming practices, but current dustiness in the US is driven by global heating, reduced water resources, and invasive plants, with the southwest seeing a significant increase in storms.
- Megadroughts and stronger winds contribute to more frequent and intense dust storms, with wind being crucial for lofting dust into the atmosphere, sometimes forming haboobs from thunderstorm downdrafts.
- As the planet becomes drier, dustiness will increase, but measures like increasing plant cover, paving dirt roads, improving forecasting, and masking can help mitigate impacts, though larger dust storms will persist unless global heating is addressed.
