White Death: Coral Kill

“Horrible.” That’s how University of Houston biologist Gerard Wellington describes the state of Easter Island’s corals. Wellington’s team found that while some types of coral survived, nearly 90 percent of the more vulnerable branching coral had been bleached. Sea temperatures as little as 1.8 degrees F (-16.8 degrees C) above normal led the coral to expel its brightly colored symbiotic algae, killing the coral. The water had been warmed by unusual Pacific Ocean currents, possibly related to global warming.
