WASHINGTON (AP) -- Even in a record-breaking hot year for Earth, October stood out as absurdly warm.
The U.S. National Oceanic and Atmospheric Administration said that last month globally was 58.86 degrees (14.98 degrees Celsius). That's the hottest October on record by a third of a degree over the old mark, a large margin for weather records.
October's temperature was the most above-normal month in history. It was 1.76 degrees Fahrenheit (0.98 degrees Celsius) above the 20th-century average.
This was the eighth month this year when a heat record was set. That's a record number of broken records in any year. Records go back to 1880.
NOAA climate scientist Jessica Blunden said 2015 will be the hottest year on record. She blamed a potent El Nino on top of accelerating man-made global warming.
