Reprint of: “Impacts of natural and anthropogenic climate variations on North Pacific plankton in an Earth System Model”

- A plankton model with variable stoichiometry has been used in a coupled climate study.
- Natural climate variations modify North Pacific plankton biomass by 10-30% while a warming scenario decreases primary production up to 50%.
- DOC production and the microbial foodweb will be favored in a warmer North Pacific.
- Positive phases of natural fluctuations counteract the impacts of global warming.
- Natural and anthropogenic impacts are distinguishable only in the second part of the 21st century.
