September 2015: Earth's warmest month in recorded history, says NOAA
September 2015 had the largest departure of temperature from average of any month among all 1629 months in the record that began in January 1880, said NOAA's National Centers for Environmental Information (NCEI) on Wednesday. (Note that since July and August are typically the warmest months globally in absolute terms, September was not Earth's warmest month in that regard.)
