Coccolithophores are single-celled algae and protists that are found throughout the surface euphotic zones of the world’s oceans. They contain chlorophyll, conduct photosynthesis and possess special plates or scales known as coccoliths, which they create via the process of calcification. This summary briefly reviews the results of several studies investigating how coccolithophores may be affected by ocean acidification in a CO2-enriched world of the future. As indicated below, the findings of these several works challenge the alarmist view of ocean acidification espoused by the IPCC and others. Instead of experiencing great harm in response to future declines in oceanic pH predicted for the future, coccolithophores will likely adapt and possible even thrive under such changes.
