It is official: No year on record has ever been as hot as 2015 since reporting began in 1880, as last year smashed the temperature record just set in 2014.

Officials from the National Oceanic Atmospheric Administration (NOAA) and NASA's Goddard Institute for Space Studies released their annual reports Wednesday.

Data shows the average global temperature in 2015 was 14.79 degrees Celsius (58.62 degrees Fahrenheit). This was 0.90°C (1.62°F) higher than the 20th-century CE average, making it the highest among all 136 years on record.

Although 2015 is now the hottest on record, it was the fourth time in 11 years that Earth broke annual marks for high temperatures.
