Temperature affects the early life history stages of corals more than near future ocean acidification
International audience Climate change is projected to increase ocean temperatures by at least 2 C, and levels of pH by similar to 0.2 units (ocean acidification, OA) by the end of this century. While the effects of these stressors on marine organisms have been relatively well explored in isolation,...

International audience Climate change is projected to increase ocean temperatures by at least 2 C, and levels of pH by similar to 0.2 units (ocean acidification, OA) by the end of this century. While the effects of these stressors on marine organisms have been relatively well explored in isolation, possible interactions between temperature and OA have yet to be thoroughly investigated.
