Our global temperature continued its upward trend last month with September 2018 tying 2017 as the fourth warmest September ever recorded on this planet.
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 60.4°F, which is 1.40°F above the 20th-century average. September also marked the 405th 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 September, some places were particularly warm, including much of Europe, Russia, the Middle East, and both the eastern and southwestern regions of the United States. For the contiguous US as a whole, September 2018 marked the fourth warmest September on record.
These soaring temperatures are largely attributed to the long-term trend of human-caused climate change. ENSO-neutral conditions prevailed in September, which means there was neither a warm El Niño nor a cool La Niña in the Pacific to influence global weather patterns.
Year to date, the first nine months of 2018 were the fourth warmest such period of any year on record. Global temperature records date back to 1880.
