      Gusting winds carried Saharan dust over the Mediterranean Sea in   
      mid-November 2022.   
      
      On November 17, the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on board NASA’s Terra satellite acquired a true-color image of   
      the start of a dust storm, with camel-colored sand and dust blown into   
      a swirling pattern between Libya (south) and Greece. Subsequent MODIS   
      images show that clouds of dust have continued to pulse over northern   
      Libya and the Mediterranean through November 19. While the exact source   
      of the dust isn’t clear, it appears to primarily rise from sand seas in   
      northern Libya.   
      
      Libya, a country about two-and-a-half times the size of the U.S. state   
      of Texas, is one of the driest countries in the world. According to the   
      United Nations Office for Coordination of Human Affairs, as of 2021,   
      the country is more than ninety-five percent desert, with most of the   
      land barren with flat to undulating plains. Only about one percent of   
      the land is arable, and the country is forced to import about 75   
      percent of the food needed to meet local needs. OCHA notes that the   
      Great Man-Made River project, which provides 60 per cent of all fresh   
      water used in Libya, draws water from non-renewable aquifers that   
      cannot be recharged by rain. The country is susceptible to floods,   
      sandstorms, dust storm and desertification. The UN notes that Libya is   
      a country living in “fragile circumstances” and it is one of the areas   
      severely vulnerable to the effects of climate change.
