Marine species are outpacing terrestrial species in the race against global warming


Global warming is causing species to search for more temperate environments to which to migrate, but it is marine species that are leading the way by moving up to six times faster towards the poles than their terrestrial congeners, according to the latest results of a Franco-American study mainly involving scientists from the CNRS, Ifremer, the Université Toulouse III—Paul Sabatier and the University of Picardy Jules Verne.

By analysing the speed of change in the distribution range of more than 12,000 animal and plant species, according to isotherm shifts in latitude and altitude, the researchers have shown that under certain conditions, marine species are capable of following the invisible migration of temperatures towards the poles.
