The devices are placed above reefs to reduce the sunlight and heat stress that can trigger coral bleaching. The unusual concept has drawn attention online, with many commenting that low-tech, physical shade could be a simple way to buy vulnerable reefs time while broader climate action catches up.","why":"The novel and unexpected idea of using umbrellas underwater to protect coral is striking, and it offers hope amid widespread concern about coral bleaching.","tone":"positive","entities":["coral
