CAN CORAL RE­COVER FROM BLEACH­ING?

BBC Wildlife Magazine - - OUR WILDWORLD -

Not all bleached corals go on to die. In fact, some re­gain their colour within days if con­di­tions im­prove. How­ever, if the bleach­ing is se­vere – as was the global event that oc­curred in 2016, killing off large num­bers of coral – it can take up to 15 years for a reef to fully re­cover. With un­der­wa­ter heat­waves oc­cur­ring more fre­quently due to cli­mate change, sci­en­tists are con­cerned that dam­aged reefs do not have suf­fi­cient time to heal.
