Earth’s surface temperature has surged high into uncharted territory, thanks to a record-strength El Niño event combined with the long-term rise in temperatures due to human-caused global warming: October 2015 was Earth’s warmest month on record by a huge margin, according to data released by NOAA's National Centers for Environmental Information (NCEI) on Wednesday. October 2015 was the second consecutive month with a new all-time warmest month record: September 2015 previously held the record for the largest positive departure of temperature from average of any month among all 1630 months in the historical record that began in January 1880.
