    Alarmismcan be good but it is nonetheless alarmism. Coral bleaches due to stress, it also recovers. (With time. So exploitation needs to stop.)

    Not necessarily. Bleaching can precipitate a one-way phase-shift to algae-dominated systems, particularly when associated with other stressors.

    Well, I can guarantee bleaching happened in the past several times. Check the molecular locks of specialised reef organisms such as butterflyfishes and damselfishes: throughout that period of time, reefs must have recovered.

    Reefs can recover, but not always, like Giant Panda said. If a reef does recover it takes time, several years. Constant bleaching events will destroy the reefs and they won't be able to recover.

    I have to say that what may or may not have happened repeatedly in the past doesn't actually have any bearing on what may happen in the future.
