Hottest September on Record Ends the Hottest Summer on Record

In the wake of the hottest month on record (July) and the hottest summer on record, the fall season began with the hottest month of September ever recorded. According to Copernicus Climate Change Service, September was not only the hottest month in the 140 years we have kept records, it was also the 417th consecutive month with above-average global temperatures. We have not seen below-average temperatures in 35 years. The four warmest decades on record have all occurred in the last 40 years. Eight of the ten warmest years have occurred in the last decade and the five warmest years in recorded history have all occurred in the past five years. This year is on track to be another record-breaker.
