Scripps research gives tiny phytoplankton a large role in Earth's climate system
... Earth's surface reflection caused by increases or decreases in phytoplankton concentrations may significantly affect the interactions of the planet's climate system with human-produced concentrations of greenhouse gases and aerosols. They also argue that the climatological significance of phytoplankton is inc...Researchers reach milestone in fight against lymphatic filariasis
