The UN's World Meteorological Organization (WMO) identified this slight rise in dust levels, attributing it to increased emissions from various regions, including west-central Africa, the Arabian Peninsula, the Iranian Plateau, and northwestern China.
"The impact of human activities on sand and dust storms is becoming more pronounced," stated WMO chief Petteri Taalas in the global weather agency's Airborne Dust Bulletin. The annual WMO report stated, "The global average of annual mean dust surface concentrations in 2022 was slightly higher than that in 2021."
In 2022, the global average was 13.8 micrograms (one-millionth of a gram) per cubic meter, compared to 13.5 in 2021. The peak estimated annual mean dust surface concentration was found in the Bodele region in Chad.
