Une étude menée par deux chercheurs de l'université de Leicester explique que le réchauffement des océans menacerait le phytoplancton, premier producteur d'oxygène de la planète.

Diatoms These single-celled algae are protected by a cell wall made of silica, which forms their characteristic geometric shapes. Thanks to this wall, diatoms are well represented in the fossil record going back to the Cretaceous. photographie de Malcolm Park/Getty

Coccolithophores The beautifully patterned calcified plates of coccolithophores mean they fossilised easily and so are commonly found in limestones and chalks. The fossil record tells us that they first became abundant in the Jurassic but suffered a mass extinction in the late Cretaceous. photographie de Steve Gschmeissner/Science Photo Library
