September GISTemp: Hottest on record (just, barely)

Sou

Initially I thought there'd been a continuous run of 12 hottest months however June 16 was revised down, so there's an interruption in the series. It's still by far the hottest 12 months on record (October 15 to September 16), and not just because of the El Nino.

From the blog article:

According to GISS NASA, the average global surface temperature anomaly for September was 0.91 °C, which is just 0.01 °C higher than the previous hottest September in 2014.
The average for the eight months to the end of September is 1.03 °C, which is 0.23 °C higher than the previous hottest January to September period in 2015, which with the latest data had an anomaly of 0.80 °C.

There are lots of charts. Here's the one tracking whether it will be another record hot year - almost certainly it will:
