Editorial: Future Oceans Under Multiple Stressors: From Global Change to Anthropogenic Impact

The current Research Topic explores futures for our oceans and coastal areas with a strong focus on effects of climate change, but also covering fishing, mass mortality events, and cumulative impacts from multiple stressors and human activities. In the Mediterranean, Moullec et al. use coupled modeling to project climate change scenarios on fish stocks and fisheries, showing an overall increase in fish biomass and catches but with large regional differences. Using a statistical modeling framework, Otto et al. explore the long-term effects of cumulative impacts on a key zooplankton species in the Baltic, showing that multiple pressures were mostly additive, but that the population effects were dampened through density dependence. Changes will not necessarily be negative for all species or habitats. [...]many of the combined effects are either dampened or synergistic, and may in some cases (Olsen et al.; Kadin et al.) show signs of hysteresis (Sguotti et al., 2019).
