The average global temperatures last year were the warmest on record, two United States agencies announced on Wednesday, officially confirming what had long been anticipated.

NASA and the National Oceanic and Atmospheric Administration (NOAA) both announced that Earth’s average temperatures in 2015 were the highest they’ve been since 1880, which is as far as records date back.

The agencies conducted separate analyses, but both reached the same conclusion.

The NOAA said global temperatures were 1.62 degrees Fahrenheit above the 20th-century average and beat last year’s record by .29 degrees.

It didn’t surprise the agency that 2015 set a new record, since it reported that record-high temperatures were recorded in 10 out of the 12 months of the year.

NASA calculated the temperatures in other ways, and had slightly different values than the NOAA, but agreed that 2015 was the warmest year since 1880.

The NOAA said an unseasonably warm December set some records of its own.

Average global temperatures during that month were 2 degrees above the 20th-century average. Not only was it the warmest December on record, but it was the only time since 1880 that any month has seen temperatures that far above its historic averages.

Though global temperatures reached new highs, not everywhere saw record warmth.

The United States, for example, experienced its second-warmest year on record, the NOAA said earlier this month. The nation’s average temperatures, while still well above average, were just shy of the all-time high established in 2012.

But record-high averages were recorded in parts of Russia, Europe, South America, and the Indian, Atlantic and Pacific Ocean, the NOAA said Wednesday.

The latter is currently the site of one of the strongest El Nino weather patterns on record, which is known for producing extreme weather throughout the world. NASA officials said the phenomenon, paired with human-induced climate change, contributed to the new records.

“Last year’s temperatures had an assist from El Niño, but it is the cumulative effect of the long-term trend that has resulted in the record warming that we are seeing,” Gavin Schmidt, the director of NASA’s Goddard Institute for Space Studies, said in a statement.

Despite the overall increases, the NOAA said some isolated areas witnessed cooler-than-average temperatures, including a swath of ocean near Greenland that posted record cold levels.
