Global record of “ghost” nannofossils reveals plankton resilience to high CO_{2} and warming
Predictions of how marine calcifying organisms will respond to climate change rely heavily on the fossil record of nannoplankton. Declines in calcium carbonate (CaCO_{3}) and nannofossil abundance through several past global warming events have been interpreted as biocalcification crises caused by o...
