April 2017: Earth’s Second Warmest on Record

Our global temperature continued its upward trend last month with April 2017 marking the second warmest April ever recorded on this planet. Only April 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 58.32°F. That is a staggering 1.62°F above the 20th-century average. April was also the 388th 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 April, some places were particularly warm, including Asia, Alaska, and the eastern United States. For the contiguous US as a whole, it was the 11th warmest April on NOAA’s books.

These soaring temperatures are largely attributed to the long-term trend of human-caused climate change. ENSO-neutral conditions prevailed in April, which means there was neither an El Niño nor a La Niña to influence global weather patterns.

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