摘要：Coral reefs are the world’s most diverse marine ecosystems that provide resources and services that beneft millions of people globally. Yet, coral reefs have recently experienced an increase in the frequency and intensity of thermal-stress events that are causing coral bleaching . Coral bleaching is a result of the breakdown of the symbiosis between corals and their symbiotic microalgae, causing the loss of pigments and symbionts, giving corals a pale, bleached appearance . Bleaching can be temporary or fatal for corals, depending on the species, the geographic location, historical conditions, and on local and regional infuences . Indeed, marine heat waves are the greatest threat to corals worldwide . Here we compile a Global Coral-Bleaching Database (GCBD) that encompasses 34,846 coral bleaching records from 14,405 sites in 93 countries, from 1980–2020 . The GCBD provides vital information on the presence or absence of coral bleaching along with site exposure, distance to land, mean turbidity, cyclone frequency, and a suite of sea-surface temperature metrics at the times of survey.
