Ocean acidification ameliorates harmful effects of warming in primary consumer
Climate change‐induced warming and ocean acidification are considered two imminent threats to marine biodiversity and current ecosystem structures. Here, we have for the first time examined an animal's response to a complete life cycle of exposure to co‐occurring warming (+3°C) and ocean acidif...

Climate change‐induced warming and ocean acidification are considered two imminent threats to marine biodiversity and current ecosystem structures.
