Climate change is warming the oceans, depleting its dissolved oxygen (O2), lowering its pH, and altering species distributions, phenology, and interactions (1). Understanding how these changes affect species fitness remains a challenge for at least two fundamental reasons. First, the role of climate in shaping habitat is mediated by numerous physiological and ecological traits that are not systematically measured and are difficult to disentangle. Second, the observational records needed to detect climate-driven ecosystem changes rarely span the decadal periods of intrinsic ocean variability (2). Attributing past species responses to multiple climate stressors is essential to projecting future climate impacts on marine ecosystems.
