New NASA satellite data find that the vital base of the ocean food web shrinks when the world's seas get hotter. The data show a significant link between warmer water and reduced production of phytoplankton of the world's oceans. 


Would the phytoplankton death and decay reduce dissolved oxygen concentrations in deeper ocean waters? If true, might that explain what caused the extinction of numerous deep-sea benthic foraminifera” (wikipedia) at the PETM? [From Wikipedia, “The end of the Paleocene (55.5/54.8 Ma) was marked by one of the most significant periods of global change during the Cenozoic, a sudden global climate change, the Paleocene-Eocene Thermal Maximum (PETM), which upset oceanic and atmospheric circulation and led to the extinction of numerous deep-sea benthic foraminifera” …]
