For the first time ever, scientists have found corals that were thought to have been killed by heat stress have recovered: a glimmer of hope for the world's climate change-threatened reefs. This was discovered by a team led by Diego
Kersting at the Columbretes islands near Spain. It concerned the species Cladacora caespitosa, which stands out as the only reef-building Madreporaria species in the Mediterranean
and adjacent Atlantic (picture left by Veronique Lamare) In some areas of the Adriatic Mediterranean sea, these corals may even occupy significant zones. The question, however, is the implication of this finding for other types of
corals in the tropical oceans.
