ABSTRACT Aim Global elevated atmosphere CO 2 concentration‐induced acidification poses a great threat to aquatic organisms worldwide. However, a comprehensive understanding of the response variability to acidification is still lacking, especially in the context of concurrent global warming. Addressing the response patterns of aquatic biota to acidification under the context of warming can facilitate the identification and prediction of probable consequences of global climate change. Location Global. Time Period 1996–2024. Major Taxa Studied Aquatic biota. Methods We performed a meta‐analysis by synthesising 221 studies containing 3669 observations to summarise the effects of CO 2 on multiple aquatic biota, including primary producers, consumers, and decomposers. We further examined the effects of different ecosystems, experimental venue, CO 2 concentration, and ambient experimental temperature on the response magnitude. Results Acidification had significant positive effect on primary producers and decomposers, yet significant negative effect on consumers. We found that invertebrates were the most negatively affected of all organisms, and the marine ecosystems are suffering more severity of acidification than freshwater ecosystems. We further found that the response magnitude showed a significant dose effect, indicating that reducing greenhouse gas emissions would minimise the impact of acidification. In addition, we found that higher temperatures enhanced the sensitivity of p...
