Short summary

Responses of the Arctic microalgae Micromonas pusilla to different pCO₂ levels were investigated at two temperatures. We observed that warming and ocean acidification (OA) synergistically increased growth rates. Furthermore, elevated temperature shifted the pCO₂ optimum of biomass production to higher levels. This seem to be caused by more efficient photosynthesis under warmer and more acidic conditions. Our findings explain the dominance of picoeukaryotes frequently observed in OA experiments.
