Carbon emissions and their ocean impacts
Anthropogenic CO2emissions directly affect atmospheric chemistry but also have a strong influence on the oceans. Gattusoet al.review how the physics, chemistry, and ecology of the oceans might be affected based on two CO2emission trajectories: one business as usual and one with aggressive reductions. Ocean warming, acidification, sea-level rise, and the expansion of oxygen minimum zones will continue to have distinct impacts on marine communities and ecosystems. The path that humanity takes regarding CO2emissions will largely determine the severity of these phenomena.
