2014 was the hottest year in 135 years of record-keeping, the National Oceanic and Atmospheric Administration and NASA announced on Friday.
The year’s average combined global land and ocean surface temperature was 58.24 degrees Fahrenheit, according to NOAA. This is 1.24 F above the 20th-century average. Global average land temperatures were 1.80 F above average, while ocean surface temperatures were 1.03 F above average, the agency said. Land temperatures alone were only the fourth-warmest on record, but ocean temperatures were the warmest, which helped to make 2014 the warmest year overall.
