Saharan Dust Storms Blanket Athens as Global Frequency and Severity Increase

Athens, Greece was enveloped in an apocalyptic orange haze on Tuesday as strong winds carried particles from the Sahara Desert across the Mediterranean Sea. The dust storm caused a deterioration in air quality, spiked temperatures, and fanned unseasonal early wildfires in southern Greece. Authorities warned that the high concentrations of dust and sand particles can reduce sunlight and visibility while increasing levels of fine pollution, posing health risks especially for those with underlying respiratory conditions.

Kostas Lagouvardos, research director at the National Observatory of Athens, described the sand cloud as more concentrated than previous episodes, calling it the "worst such case in years." The Greek Health Ministry urged people to avoid outdoor exercise and keep doors and windows closed due to the dangerous desert dust particles in the atmosphere that can penetrate deep into the lungs. Many people needed emergency medical care for respiratory issues.

The dust storm created remarkable scenes around Athens' iconic Acropolis and other parts of the city, with the skies becoming an eerie deep red hue on April 23rd. While the dust was expected to gradually dissipate starting Wednesday as winds ease, the event highlighted a concerning global trend of increasing frequency and severity of dust storms that is prompting scientists to investigate.

Why this matters: The intensifying dust storms originating from the Sahara Desert are having substantial transboundary impacts, affecting various aspects of the environment, climate, well-being, agriculture, and socioeconomic well-being across multiple regions. Understanding the underlying causes and developing tools to combat this growing threat is crucial as scientists warn of a potentially dustier future for the planet.

The Sahara Desert releases an estimated 60 to 200 million tonnes of mineral particles per year, with the smallest particles capable of traveling thousands of kilometers and potentially reaching all of Europe. Similar dust events have recently smothered parts of Greece, Switzerland, southern France, and Cyprus. A powerful sandstorm also hit eastern Libya, disrupting air traffic and shutting down airports, public administration, and schools in the region.

Experts point to factors such as deforestation, overgrazing, soil erosion, and climate change as potential contributors to the increasing sandstorms. "Dust storms may become more frequent and severe due to human-induced factors like desertification, deforestation, and increased urbanization," warned scientists studying the trend. The dust storms have also contributed to worsening drought conditions and raising concerns about an especially challenging upcoming wildfire season in
