Contrary to conventional wisdom, sulphur production by tiny marine algae decreased during glacial periods, and is more closely linked to climate than previously thought, according to the latest research by scientists in Japan. A clearer understanding of the link between the climate and marine phytoplankton, the microscopic single-celled algae that live in the surface waters of the ocean, can help scientists incorporate these impacts in future climate models....
