“November 2015 was Earth’s warmest November on record by a huge margin, according to data released by NOAA’s National Centers for Environmental Information (NCEI) on Thursday. November 2015 also had the second largest positive departure of temperature from average of any month among all 1631 months in the historical record that began in January 1880; only last month (October 2015) was more extreme.”
