Lo scorso anno è stato di gran lunga il più caldo dal 1880, ovvero da quando si hanno a disposizione i dati climatici terrestri. La notizia, finora presumibile ma mai ufficiale, è stata certificata dalla NASA e dall’Agenzia federale degli Stati Uniti per la meteorologia (NOAA).
La temperatura media globale sulla terraferma e sulla superficie oceanica è stata di 0,9 gradi centigradi superiore alla media del XX secolo. È la cifra più alta mai registrata negli ultimi 136 anni, e supera il record del 2014 di 0,16 gradi. La temperatura sulla superficie terrestre è stata più alta di 1,33 gradi rispetto alla media; quella della superficie marina ha registrato +0,74 gradi sopra la media.
La colonnina di mercurio ha toccato il picco anche lo scorso dicembre, che con 1,11 gradi sopra la media è stato il più caldo di sempre. Nel corso del 2015 sono stati 10 i mesi che hanno segnato un primato delle temperature, con le sole eccezioni di gennaio e aprile.
