Abstract: "Scientists say that coral reefs are currently undergoing a global bleaching event, with more than 54% of the world’s coral reef areas in the territorial waters of over 50 countries experiencing heat stress. According to one scientist, the percentage of areas dealing with bleaching-level heat stress “has been increasing by roughly 1% per week.” To assess the current bleaching event, scientists drew on satellite-derived sea surface temperature data and in-water measurements. Experts say the current El Niño, a phase in the El Niño–Southern Oscillation (ENSO) climate pattern, in combination with rising global sea temperatures, is responsible for the extensive coral bleaching. Mongabay interviewed scientists most familiar with coral reef bleaching data, and experts attending the 9th Our Ocean Conference in Athens, taking place from April 15-17."
