March 2017: Earth’s Second Warmest on Record

Our global temperature continued its upward trend last month with March 2017 marking the second warmest March ever recorded on this planet. Only March 2016 was warmer.

According to the state of the climate report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the month – over both land and sea surfaces – was 56.79°F. That is a whopping 1.89°F above the 20th-century average. March was also the 387th 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 in March, some places were particularly warm, including the United States, Europe, and Russia. For the contiguous US, despite the cool conditions in the northeast, it was the 9th warmest March on NOAA’s books.

These soaring temperatures are largely attributed to the long-term trend of human-caused climate change. In fact, March 2017 marked the first time a monthly temperature departure from average surpassed 1.8°F (1.0°C) in the absence of an El Niño event.

Year to date, the first quarter of 2017 was the second warmest such period of any year on record. Global temperature records date back to 1880.
