• Emerging phytoplankton climate responses include: (1) range expansion of warm-water at the expense of coldwater species; (2) changes in abundance and seasonal bloom window; (3) increased cellular toxin content of harmful algal bloom species; and (4) secondary effects for marine food webs, when individual zooplankton and fish grazers are differentially impacted by climate change.
• Developing predictive capability has been frustrated by: contradictory species and especially strain-specific responses; lack of insights into evolutionary adaptation and how harmful algal species interact with the broader phytoplankton and zooplankton grazer communities; and scarcity of sustained biological data streams. Unexplored factor interactions may underpin differing climate responses by different geographic ocean provinces.
• To progress phytoplankton climate science, we need better science including agreement on ‘best practices’ experimental protocols, use of biological reference organisms and climate ‘hot-spot’ observer sites. We also need better data streams through more investment in global observation systems and improved ocean sensor capabilities. Finally, we need better integrated and coordinated research communities in order to define management options and better forecast risks to human health and seafood security.
