Si è aperta lunedì a Varsavia la 19esima conferenza dell’ONU sui cambiamenti climatici, che riunisce per una decina di giorni rappresentanti di oltre 190 paesi.
L’obiettivo è di dare nuovo slancio alla lotta contro il surriscaldamento globale e gettare le basi per un accordo da siglare nel 2015 a Parigi.
Secondo Christiana Figueres, responsabile per le Nazioni Unite del dossier, il tifone che si è appena abbattuto sulle Filippine, devastandone intere aree e provocando migliaia di morti, è un'ulteriore prova di quanto sia necessaria un’intesa internazionale.
Il legame tra cicloni e mutamenti climatici è un punto controverso nella comunità scientifica, la quale si aspetta in genere un aumento degli "episodi violenti" con il rialzo della temperatura degli oceani.
