The equinox on September 22 marked a seasonal milestone for planet Earth. It signified a rapid progression into autumn for those of us in the Northern Hemisphere and spring for those “down under” in the Southern Hemisphere.
Let’s dive deeper into our monthly analysis to see how the planet fared for the month and the year to date:
Climate by the numbers
The average global temperature set in September 2017 was 1.40 degrees F above the 20th-century average of 59.0 degrees, according to scientists from NOAA’s National Centers for Environmental Information. This average temperature was the fourth highest for September in the 1880-2017 record. This marked the 41st consecutive September and the 393rd consecutive month with temperatures above the 20th-century average.
