January 2017: Earth’s Third Warmest January on Record

Our global temperature continued its upward trend last month with January 2017 marking the third warmest January ever recorded on this planet. Only the Januarys of 2016 and 2007 were warmer.

According to a report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the month – over both land and sea surfaces – was 55.18°F. That is 1.58°F above the 20th-century average.

January was also the 385th consecutive month with a global temperature above its long-term norm. That means the last time any month posted a below average reading was December 1984.

While heat dominated most of the planet this January, some places were particularly warm, including the eastern half of the United States and most of Canada. For the contiguous US as a whole, it was our 18th warmest January on NOAA’s books.

Coming on the heels of 2016 – Earth’s third consecutive warmest year on record – these soaring temperatures are largely attributed to the long-term trend of human-caused climate change. Whereas El Niño gave global temperatures a boost in the early part of last year, it dissipated in the spring. ENSO-neutral conditions prevailed in January.

Global temperature records date back to 1880.
