Climate change pressures are anticipated to substantially influence marine planktonic systems globally, and it is conceivable that harmful algal blooms may increase in frequency and severity. However, this coupling of climate with HAB outbreaks is based on few and sometimes conflicting data, frustrating hopes for developing consensus forecasts of HABs in the future ocean. Moreover, it is not clear that many of our current research strategies are best suited to inform on the essential fundamental linkages. We report here the outcome of a 4-day workshop aimed at summarizing key aspects of what currently is known and not known about the general environmental conditions that favor initiation and maintenance of different types of HAB events. Using the anticipated changes in ocean acidification, nutrient flux, temperature, light, and grazing in the future ocean, we review the known and unknown consequences of climate change on these factors that can impact the intensity, type and duration of future HABs. The goal is to provide a starting point to identify a list of keystone research directions and infrastructure that would best serve to begin testing the purported coupling of HABs and climate change.
