- Unusually hot ocean temperatures in 1998 stressed corals worldwide, causing them to expel the microalgae in their tissues that normally nourish them and give them color, according to the source.
- More than 20 percent of the world's reefs turned white over the following year during what the source describes as the first global coral bleaching event.
