The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.

Des débris et déchets marins menacent le littoral isolé de l'Antarctique et ses écosystèmes marins uniques. Car sur ces déchets peuvent se greffer des espèces étrangères à l'Antarctique.

This Southern Ocean warming and its associated impacts are effectively irreversible on human time scales, because it takes millennia for heat trapped deep in the ocean to be released back into the atmosphere. This means changes happening now will be felt for generations to come – and those changes are only set to get worse, unless we can stop carbon dioxide emissions and achieve net zero.
