Clive Wilkinson identified four overlapping levels of coral bleaching.
• Catastrophic bleaching adversely affecting
95 per cent of shallow water corals.• severe bleaching accounting for
50-70 per cent death of corals.
• moderate bleaching resulting into
20-50 per cent coral mortality but with quick recovery.
• insignificant bleaching or no bleaching.
