L'Antartide è vicina ad un punto critico: lo rivela la mappa dei cambiamenti nelle temperature dell'Oceano, circostante il Polo sud, avvenuti negli ultimi 45 milioni di anni. I dati indicano che un ulteriore scioglimento dei ghiacci potrebbe causare un catastrofico aumento nel livello del mare, anche di 50 metri.
La mappa, ottenuta combinando i dati relativi a microfossili di singole molecole con l'Intelligenza Artificiale, conferma inoltre le recenti previsioni relative ai 16 punti sorvegliati speciali del pianeta, che includono la scomparsa delle piattaforme di ghiaccio antartiche tra i 5 eventi più vicini al punto di non ritorno a causa dell'aumento delle temperature. Lo studio, guidato da Università Victoria di Wellington, in Nuova Zelanda, e Università britannica di Birmingham, è stato pubblicato sulla rivista Nature Geoscience.
