October 2015: Earth's Warmest Month on Record by a Huge Margin By: Jeff Masters , 4:54 PM GMT on November 18, 2015 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 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. As shown in the table below, October 2015's 0.98°C (1.76°F) departure from the 20th Century average beat the next ten runners-up by an unusually large margin, underscoring how unusual and extreme the current surge in global temperatures is. NASA also rated October 2015 as the warmest month in the historical record by a large margin, again defined as the largest positive departure from average (note that in an absolute sense, Earth's warmest month is July, but NOAA and NASA do not keep track of global temperature records in an absolute sense.) October 2015's warmth makes the year-to-date period (January - October) the warmest such period on record, according to both NOAA and NASA. October 2015 was the sixth consecutive month a monthly high temperature record has been set in NOAA's database, and the eighth month of the ten months so far in 2015. The potent El Niño event in the Eastern Pacific that crossed the threshold into the "strong" category in early July continued to intensify into mid-November. Strong El Niño events release a large amount of heat to the atmosphere, typically boosting global temperatures by at least 0.1°C. This extra bump in temperature, when combined with the long-term warming of the planet due to human-caused emissions of heat-trapping gases like carbon dioxide, makes it virtually certain that 2015 will be Earth's second consecutive warmest year on record. The lingering warmth from El Niño is likely to make 2016 a good bet to exceed even 2015's warmth. NOAA's top ten warmest global monthly departures from the 20th Century average: 1) 0.98°C, Oct 2015 2) 0.91°C, Sep 2015 3) 0.89°C, Mar 2015 4) 0.88°C, Feb 2015 4) 0.88°C, Jan 20076) 0.87°C, Aug 2015 6) 0.87°C, Jun 2015 8) 0.86°C, Feb 1998 9) 0.85°C, May 2015 10) 0.85°C, Mar 2010wunderground.com
