world's reefs, written by Amber Dance and read by Kerry Smith. Anne Cohen dropped into the ocean

off the coast of the Phoenix Islands, expecting to find desolation. It was 2018 and a powerful

El Nino weather system two years earlier had

warmed the waters around the mid-Pacific atoll by nearly three degrees Celsius. Coral reefs simmered

in which almost 70% of corals had expired.
