Extended Data Fig. 7: Projected Impacts of Climate Change on Phytoplankton Biomass between pre-industrial (1860) and future (2090-2100) conditions, based on alterations in temperature, nutrient supply, mixing, and ocean circulation anticipated under high warming scenario.
From: Future ocean warming may cause large reductions in Prochlorococcus biomass and productivity
Depth-integrated biomass of different phytoplankton types under pre-industrial conditions and percent difference from a high warming scenario for the period 2090-2100. Two different thermal response functions for Prochlorococcus are used: metabolic (columns 1 and 2) and exponential (columns 3 and 4). Pre-industrial biomass (10-year mean, mgC m2) for various phytoplankton types and total biomass, using the metabolic (column 1) and exponential (column 3) functions for Prochlorococcus. Percent change in biomass between pre-industrial and future conditions under a high warming scenario, using the metabolic (column 2) and exponential (column 4) functions. Positive values indicate an increase in biomass in the future scenario. Increases in biomass for specific phytoplankton types suggest niche shifts, with some groups outcompeting others.
