    According to NASA, October 2015 averaged 1.04 degrees Celsius above the 1951-1980 mean, making October 2015 the warmest October on record by a large margin globally. The previous record for October was +0.86 C. set in October 2014. The highest anomaly during the strongest El Nino of 1997-98 was +0.88 C. El Nino's typically have a warming influence on the overall global temperature.

    Even more impressive is the fact that the global land/ocean temperature anomaly for October 2014 (+1.04 C.) was the highest anomaly for any month of the year going all the way back to 1880 when records began. The previous highest anomaly was +0.97 C. set in January 2007.

    Based on this new data, I would say that there is a 99.9 percent chance that 2015 will end up as the warmest year on record globally (NASA & NOAA surface databases), sending 2014 into second place.
