Short summary
We conducted a microcosm experiment on a natural phytoplankton community under year 2100 predicted CO2 concentrations and temperature. Biomass and photosynthetic rates were significantly increased by elevated CO2 and elevated temperature. In contrast, the combined influence of these two factors had little effect. This suggests coastal phytoplankton productivity may not be influenced by future conditions. However, the combined influence promoted the greatest diversity and increased HAB species.
