Fig. 3: The CO2-eq feedback of phytoplankton in global lakes.
From: Global lake phytoplankton proliferation intensifies climate warming

a The regional pattern of the CO2-eq feedback capacity; (b) the feedback size across a span of 10 degrees of latitude; The data in (a) are the feedback extent (t/d) of phytoplankton in various continental lakes. The CO2-eq is calculated on the 100-year horizon. CO2-eq represents CO2-equivalents.
