<div>Under the business-as-usual greenhouse gas-emissions trajectory that the planet is currently following, future high ocean warming will be accompanied by high levels of ocean acidification and changes in cloud cover. Therefore, now is a prescient time to resolve the effect of ocean acidification on thermal and light-induced coral bleaching. In this study, we exposed the coral Pocillopora damicornis to two levels of ocean acidification combined with two levels of irradiance for 8 weeks, and these factors combined with two levels of ocean warming for one week. Temperature stress was applied only in the last week, because we wanted to provide corals with a long exposure to ocean acidification, but an equally long period of temperature stress would likely have resulted in high morality. We hypothesised that:<br></div>
