The 2015 Paris Agreement advances the ambitious goal of trying to keep the global average temperature to less than 1.5°C higher than preindustrial levels, but current national pledges to reduce emissions are insufficient to achieve that target. The Ocean Solutions Initiative examined what steps might be taken to mitigate three major climate-related changes in the ocean—warming, acidification, and sea-level rise—as part of that effort. Gattuso et al. summarize the suggestions, limitations, and trade-offs discussed in the Initiative, finding that global-scale actions have both the greatest potential impact and the largest limitations and risks, whereas more-local efforts are less risky but also less effective. A combination of global and local efforts has the greatest potential benefit.
