Atmospheric dust levels show 10% decrease over two decades
Satellite imagery has captured massive Saharan dust clouds moving from North Africa across the Atlantic Ocean. One notable image, selected by NASA’s Astronomy Picture of the Day project, was captured by the SeaWiFS instrument, showing a dust mass extending over 1,000 miles (approximately 1,600 kilometers).
Separately, researchers from the University of California, Los Angeles (UCLA) have identified a significant trend in atmospheric dust levels. According to a study published in Science Advances, there was a 10% decrease in the amount of dust reaching the atmosphere between 2003 and 2023. This decline contrasts with the 20th century, where dust levels increased annually until peaking in 1980. Scientists are currently investigating the causes of this decrease and its potential implications for climate change.
