Scientists say warming seas could kill off coral reefs in Pacific, Atlantic oceans

Coral reefs are essential to ocean health, but dangerous coral bleaching is occurring more often and more widely due to warmer water, scientists report

Abnormally warm ocean temperatures are creating conditions that threaten to kill coral in the equatorial Pacific, north Pacific and western Atlantic oceans, the National Oceanic and Atmospheric Administration said on Monday.

Coral bleaching occurs when coral is stressed by changes in its environment, causing it to release algae living in its tissue. The coral then turns pale or white and becomes more susceptible to disease. In severe cases, it can die, permanently changing the habitat for fish and shellfish.
