Plankton Can Make Clouds To Block UV
NotWallaceStevens writes "This article on Science Daily describes how plankton can create clouds in response to seasonal variations in UV radiation from the sun by producing a chemical called dimethylsulfoniopropionate (DMSP). This was a long term study based on data going back to the 1950s collected in the Sargasso Sea. One of the researches theorizes that the process could slow global warming."
What global warming?
