“Coral bleaching” occurs when coral polyps lose their symbiotic algae, the zooxanthellae. Without their zooxanthellae, the living tissues are nearly transparent, hence the name coral bleaching. Many different kinds of factors can cause coral bleaching for example water that is too cold or too hot, too much or too little light, or the dilution of seawater by lots of fresh water can all cause coral bleaching. The biggest cause of bleaching however today is attributed to rising temperatures A lot of research on the cause of bleaching has focused on water temperature.
However, a team of Australian researchers hypothesized that other factors might be important too. Specifically, they tested the hypothesis that high carbon dioxide levels, which make ocean waters more acidic, might also promote bleaching.
