In the Caribbean, aid groups are struggling to bring food and water to increasingly desperate residents, as the overall death toll from Hurricane Irma rose to at least 77. French officials said they’ve launched one of the biggest airlifts since World War II in order to bring relief to the island of Saint Martin, where 90 percent of buildings were damaged when Irma made landfall with Category 5 winds. On Saint John, part of the U.S. Virgin Islands, where at least four people have been reported dead, FEMA recovery workers are searching for 30 people missing amid the island’s rubble. The devastation in the Caribbean is so severe, it can be seen from space. Before-and-after satellite photos released by NASA’s Earth Observatory show Barbuda and Saint Barthélemy turned from green to brown after Hurricane Irma stripped vegetation from the islands.
