The California EBUS is arguably the best-studied of the four ecosystems in terms of robust projections of climate change, although even here, there is limited evidence and low agreement among projections. For example, trends in outputs from high-resolution, downscaled models in the California EBUS generally reflect those from underlying coarser-scale ESMs, but projections for physical variables are more convergent among modelling approaches than are those for biogeochemical variables  . Models agree on general warming in the California EBUS, with concomitant declines in oxygen content  . But implications for the future spatial distribution of species, including for some fisheries resources (Howard
