When viruses infect phytoplankton, it can change the clouds
(World News Science)

Microscopic plant-like organisms called phytoplankton are known to support the diversity of life in the ocean. Scientists in Israel now report that one species, Emiliania huxleyi, and a virus closely associated with it, might be responsible for changes in cloud properties as well. When infected, E. huxleyi releases its chalky shell into the air, where it acts as an aerosol reflecting sunlight and even affecting cloud creation and movement. The research appears August 15 in the journal iScience. ......
