Rising temperatures and declining marine biodiversity


According to a study conducted by scientists french and Australian, the explosion in marine biodiversity, there are 460 million years, is due to a drop in ocean temperature.

Scientists at the laboratory CNRS-Insu Paléoenvironnements paléobiosphère and Lyon, in partnership with the University of Canberra, were able to determine the temperature of ocean waters in Ordovician through measures of oxygen isotopes in fossils of conodonts. It seems that this time there was a significant greenhouse effect, leading to sea temperature of 45 ° C and that the lower temperatures then allowed to marine biodiversity explode. The reverse could happen
