Biochemical remodelling of phytoplankton cell composition under climate change

Nature Climate Change, Published online: 31 March 2026; doi:10.1038/s41558-026-02598-wThe authors simulate phytoplankton macromolecular composition—proteins, carbohydrates and lipids—under present and future scenarios. They show increased protein allocation in subtropical phytoplankton but declines in high-latitude populations under warming, with implications for marine food webs.
