Our global temperature continued its upward trend last month with November 2016 marking not only the fifth warmest November on record but also closing out the second warmest meteorological autumn ever recorded for the entire planet.
According to a report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for November – over both land and sea surfaces – was 56.51°F. That is 1.31°F above the 20th-century average and only 0.41°F shy of the record that was set last year.
The three-month period of September, October, and November – known as the meteorological autumn in the northern hemisphere – was also one for the record books. With the season posting an average temperature that was 1.39°F above the 20th century average, it was the Earth’s second warmest September to November period on record.
While heat dominated most of the planet these past three months, some places were particularly warm. Here in the contiguous US, the autumn of 2016 was our warmest on record. Nearly every state experienced above average temperatures and eight were record warm – Colorado, Iowa, Kansas, Michigan, Minnesota, New Mexico, Texas, and Wisconsin.
These soaring temperatures are attributed to the long-term trend of human-caused climate change. Whereas El Niño gave global temperatures a boost earlier in the year, it dissipated in June. In fact, its cooler counterpart, La Niña, prevailed across the tropical Pacific Ocean this November.
Year to date, the first eleven months of 2016 were the warmest of any year on record. It is now almost certain that 2016 will surpass 2015 as the Earth’s warmest year ever recorded. Global temperature records date back to 1880.
