Mashable: “The planet has not been only record warm this year, it’s been so unusually mild that the temperature records themselves have set records of their own. This is the case with October 2015, according to new preliminary NASA data released Tuesday.”

“The information shows that October 2015 was by far the warmest October on record, dating back to 1880. Not only that, but October also had the largest temperature departure from average of any month on record.”

“Importantly, this was also the first time that a single month exceeded the 1-degree Celsius temperature anomaly, surpassing the 0.97 degree Celsius temperature anomaly in January 2007. This is a symbolic milestone, but one that will be broken more frequently as the climate continues to warm due to increasing amounts of greenhouse gases in the air because of human activities.”

“According to NASA, the January through October period ranks as the warmest such period in its 136 years of record-keeping, with a temperature anomaly of 0.82 degrees Celsius, or 1.45 degrees Fahrenheit. This beats global average temperature anomalies for the same period last year, which was 0.76 degrees Celsius, or 1.37 degrees Fahrenheit above average.”
