A new report by the United Nations’ World Meteorological Organization (WMO) has found that sand and dust storms are leading to “premature deaths” due to climate change, with more than 330 million people in 150 countries affected.

On Saturday, the UN General Assembly (UNGA) marked the International Day of Combating Sand and Dust Storms and its designation of 2025 – 2034 as the UN Decade on Combating Sand and Dust Storms.

The storms “are fast becoming one of the most overlooked yet far-reaching global challenges of our time”, said Assembly President Philemon Yang. “They are driven by climate change, land degradation and unsustainable practices.”

The secretary-general of WMO, Celeste Saulo, said on Thursday that sand and dust storms do not just mean “dirty windows and hazy skies. They harm the health and quality of life of millions of people and cost many millions of dollars through disruption to air and ground transport, on agriculture and on solar energy production.”
