Global warming feedback loops

Global warming kills phytoplankton that take up CO2

Global warming will stifle life-giving microscopic plants that live in the surface layer of the oceans, cutting marine food production and accelerating climate change, according to a study published on Wednesday.

Phytoplankton are not only the foundation of the marine food chain, but every day they take more than 100 million metric tons of carbon dioxide out of the atmosphere, scientists from Oregon State University, NASA and four other institutions said.
