USA It has been known for awhile now that Saharan dust often travels across the Atlantic Ocean and lands on several Caribbean Islands. Recently, Thomas Cahill, a professor at the University of California at Davis, found that Saharan dust travels beyond the Caribbean. Besides reducing visibility, these dust particles are chemically alkaline, which may dilute sulfuric acid, a main component of acid rain.
Research continues into the global transport of Saharan dust and other global transport connections.
