Climate change is altering oceanic conditions in a complex manner, and the concurrent amendment of multiple properties will modify environmental stress for primary producers. So far, global modelling studies have focused largely on how alteration of individual properties will affect marine life. Here, we use global modelling simulations in conjunction with rotated factor analysis to express model projections in terms of regional trends in concomitant changes to biologically influential multi-stressors. Factor analysis demonstrates that regionally distinct patterns of complex oceanic change are evident globally. Preliminary regional assessments using published evidence of phytoplankton responses to complex change reveal a wide range of future responses to interactive multi-stressors with <20–300% shifts in phytoplankton physiological rates, and many unexplored potential interactions. In a future ocean, provinces will encounter different permutations of change that will probably alter the dominance of key phytoplankton groups and modify regional productivity, ecosystem structure and biogeochemistry. Consideration of regionally distinct multi-stressor patterns can help guide laboratory and field studies as well as the interpretation of interactive multi-stressors in global models.

Phytoplankton growth and the interaction of light and temperature: A synthesis at the species and community level (2016, background): “Phytoplankton are very sensitive to environmental change (Doney et al. 2012), and both temperature and irradiance are among the key environmental drivers whose distribution is predicted to continue changing in the future (De Stasio et al. 1996; Boyd et al. 2015).”
Interactive effects of acidification, hypoxia, and thermal stress on growth, respiration, and survival of four North Atlantic bivalves (2018, background): “…found that the addition of a third stressor significantly changed interactive effects in two-thirds of studies, doubling the number of synergistic interactions (Crain et al. 2008) and indicating that synergies may be common in ecosystems where multiple stressors are present (Boyd et al. 2015).”
