Bene, ora siamo pronti a leggere questa news da EurekAlert:<\/p>\n<p><a href=\"https:\/\/www.eurekalert.org\/pub_releases\/2018-06\/uori-rdv062618.php\" target=\"_blank\" rel=\"noopener\">Researchers discover volcanic heat source under glacier<\/a><\/p>\n<p>Dunque, il Pine Island Glacier \u00e8 giunto alla ribalta delle cronaca nel novembre scorso, perch\u00e9 dalla parte terminale del ghiacciaio, quella che giace sul mare, si stacc\u00f2 un iceberg enorme.

La traccia di questo calore \u00e8 un isotopo dell&#8217;Elio, che gli scienziati hanno trovato in abbondanza nell&#8217;acqua di mare dell&#8217;area, definendolo un &#8220;impronta digitale&#8221; dell&#8217;attivit\u00e0 vulcanica.<\/p>\n<p>Tuttavia, si affrettano a scrivere, pur dovendo considerare questo fattore nell&#8217;immaginare il futuro della stabilit\u00e0 del ghiacciaio, ci sono decenni di ricerca che testimoniano gli assalti del cambiamento climatico, per cui, certamente, non \u00e8 per quello che il ghiacciaio si sta sciogliendo.<\/p>\n<p>Quindi, finiamo da dove abbiamo iniziato e ripetiamo:\u00a0&#8220;<em>Non \u00e8 il vulcano a sciogliere il ghiaccio ma il clima che cambia<\/em>&#8220;.<\/p>\n<p>Buona giornata
