Earth Posts Third Warmest August and Summer on Record

Our global temperature continued its upward trend last month. August 2017 marked not only the third warmest August on record but also closed out the planet’s third warmest June to August period, which is known as meteorological summer in the northern hemisphere.

According to the State of the Climate report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for August – over both land and sea surfaces – was 61.59°F, which is 1.49°F above the 20th-century average. Only August 2015 and 2016 were warmer.

This August also marked the 392nd 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.

The three-month period of June, July, and August was also unusually warm. NOAA reports that Earth’s average temperature for the season was 1.46°F above the 20th century average of 60.1°F. That makes it the third warmest such period on record, trailing only the 2016 and 2015 seasons.

While heat dominated most of the planet this summer, some places were particularly warm, including parts of Europe, the Middle East, and the western United States. For the contiguous US as a whole, it was our fifteenth warmest summer on record.

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

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