Short summary

Emiliania huxleyi and Gephyrocapsa oceanica are the most prolific calcifying phytoplankton in today's oceans. We compare their sensitivity to combined anthropogenic stressors of temperature, light and CO₂. For the future, we project a niche contraction for G. oceanica. Furthermore, there was good correlation of our new metric, the CaCO₃ production potential, with satellite-derived concentrations in the modern ocean, indicating means of assessing overall coccolithophorid success in the future.
