I livelli dei ghiacci nell'Oceano Artico hanno raggiunto il livello più basso di tutti i tempi, battendo così il record dello scorso anno. Il 24 marzo la superficie totale misurata era infatti di 14,52 milioni di chilometri quadrati, ovvero 0,02 in meno rispetto a quanto rilevato solo un mese fa, il 25 febbraio.
“Non ho mai visto un inverno così caldo” ha dichiarato Mark Serreze, direttore National Snow and Ice Data, che ha effettuato le misurazioni in collaborazione con la NASA.
Fa sempre più caldo
La temperatura dell’aria sopra il Mar Glaciale Artico nei mesi di dicembre, gennaio e febbraio è stata dai 2 ai 6 gradi superiore alla media. Una situazione che ha interessato l’intero pianeta: il secondo mese dell’anno è stato globalmente più caldo di 1,35 gradi rispetto alle medie misurate dal 1951 a questa parte.
