Hurricanes may be unlikely saviours of coral reefs
Hurricanes Katrina and Rita may have been unlikely saviours for the coral reefs under their paths, say researchers. They have found evidence that the cooling effect hurricanes have on sea temperatures may help corals recover from the bleaching caused by warming oceans.
..."It is a controversial debate at the moment, but if the frequency of hurricanes increases with global warming, then the negative effects that are expected for coral bleaching [due to ocean warming] could be mitigated by the cooling that the hurricanes bring about"...
