where are the coccolithophores?

This map shows where the well-known species of coccolithophores live, overlaid on particulate inorganic carbon (PIC) measurements retrieved by the MODIS satellite.

How would CO2 mitigation help slow warming impacts on net primary production in the ocean?

Regions where the blue dashed bars are more separate from the red ones are where cutting CO2 emissions would help climate change impacts on the production of marine algae. Regions where they overlap are places where climate change impacts are unavoidable.
